      <description>One of the most common questions we hear from Devon homeowners: who pays for clearing a blocked drain? The answer depends on where the blockage is — and it&apos;s not always obvious.</description>
      <content:encoded><![CDATA[One of the most common questions we get from homeowners in Tavistock, Okehampton, and Launceston is this: if a drain blocks, who is responsible for clearing it — me or South West Water?

The answer depends on exactly where the blockage is located. Get it wrong and you could end up paying for clearance on a drain that South West Water should have fixed, or waiting for a utility company to respond when the problem is actually yours to deal with.

## The Simple Rule

**Within your property boundary:** The private lateral drain — the pipe that runs from your property to the shared sewer — is your responsibility. If the blockage is within your boundary, you arrange and pay for clearance.

**On the shared sewer:** Since October 2011, South West Water took over responsibility for private sewers in the South West. A shared sewer is any pipe serving two or more properties. If the blockage is on a shared sewer, South West Water should deal with it.

## The 2011 Transfer — What Changed for Devon Homeowners

Before October 2011, private sewer pipes serving more than one property were often the joint responsibility of the households connected to them — a confusing and frequently disputed arrangement. The Water Industry Act 2010 changed this, transferring ownership of those shared private sewers to water companies.

For Devon homeowners, this means that most shared sewer pipes running between properties and through gardens — the sections beyond your property boundary that connect to the main public sewer — are now South West Water's problem to fix. Many homeowners in older Devon properties are still unaware of this and pay for clearance on pipes that South West Water should be maintaining.

## Where It Gets Complicated

In older Devon properties — particularly Victorian terraces in Tavistock, Okehampton, and Launceston — the boundary between private lateral and shared sewer is not always obvious. The drainage layout may not be documented, drainage runs may have been modified over the decades, and pipe routes in rural properties are often unknown.

The safest way to resolve this is to have a [CCTV drain survey](/services/cctv-drain-survey/) carried out. The camera shows exactly where the blockage is and helps identify whether the pipe at that point is private or shared. We carry out CCTV surveys across the full service area.

## How to Check If Your Drain Is Private or Shared

A few quick checks before calling anyone:

**Step 1: Look at your property.** If you are in a terraced row or semi-detached house, there is almost certainly a shared drain serving your row. The section within your garden boundary is private; beyond it is likely shared.

**Step 2: Check for an inspection chamber.** Most properties have at least one inspection chamber (a drain cover) in the garden or driveway. If it is inside your boundary, the pipe at that point is yours. If the nearest chamber is outside your boundary — in the pavement, alleyway, or road — you may be on a shared sewer.

**Step 3: Request drainage maps.** South West Water can provide drainage maps for your address. These show the registered public sewers. What they do not always show is the section transferred in 2011 — those older private sewers that became SWW's responsibility. This is where it gets genuinely ambiguous.

If you are uncertain, a [CCTV drain survey](/services/cctv-drain-survey/) is the quickest and most definitive way to know.

## What South West Water Will and Won't Do

South West Water will investigate and clear blockages on shared sewers they are responsible for, but response times for non-emergency callouts can be several days or longer. If a [blocked drain](/services/blocked-drains/) is backing up into your property or creating a health hazard, you may decide to get it cleared privately first and then seek reimbursement — though this is not guaranteed.

South West Water will NOT deal with:
- Blockages on your private lateral drain
- Drainage within your property (soil stacks, internal pipes)
- Soakaway or septic tank issues (these are always the property owner's responsibility)

## Rural Devon Properties: Septic Tanks and Private Drainage

For properties with septic tanks or private drainage systems — common in rural Devon, particularly on Dartmoor and in the Tamar Valley — there is no shared sewer at all. All drainage maintenance is entirely the property owner's responsibility. This includes the septic tank itself, soakaway, and all drainage runs.

Septic tank drainage problems present differently from mains sewer blockages. Signs include slow drainage from all outlets simultaneously, gurgling noises from ground-floor drains, wet or soggy ground over the soakaway, and in serious cases sewage surfacing in the garden. If you are seeing any of these, the soakaway is saturated or the septic tank needs emptying — not a straightforward drain clearance job.

A property with a septic tank in an area like Dartmoor or the Tamar Valley has no South West Water involvement at all. If you are buying a rural Devon property, check the drainage type before exchange. Properties described as having a 'private drainage system' mean septic tank or cesspit — the full maintenance cost is yours.

## What a CCTV Drain Survey Actually Shows

A [CCTV drain survey](/services/cctv-drain-survey/) involves pushing a waterproof camera through your drain pipes to inspect them from the inside. The engineer can see:

- The location and nature of any blockage
- Root intrusion from garden trees (very common in Devon properties with mature hedgerow trees and ashes)
- Displaced or broken joints (common in clay pipe drainage in older Devon properties)
- The pipe material and condition
- Where the pipe exits your property boundary and connects to the shared system

The survey footage is recorded, and you receive a written report showing the camera findings with a map reference for the blockage location. If the problem is within South West Water's section, the report gives you evidence to present to them.

## Cost Guide: Private Drain Clearance in Devon

For a standard [blocked drain](/services/blocked-drains/) within your property boundary, expect to pay in the range of £80–£180 depending on access and method. High-pressure jetting costs more than rodding but is more effective for recurring blockages and grease build-up. A CCTV survey typically costs £120–£250 and is worth doing on any recurring blockage or before buying an older property.

If the blockage is on a shared sewer, South West Water must deal with it at no cost to you. If you have it cleared privately first and then discover it was their responsibility, seeking reimbursement is possible but not automatic — you will need evidence of the blockage location.

## Our Advice

If you are not sure who is responsible for a blocked drain at your Devon property, the quickest answer is usually to have the drain inspected first. We can [clear the blockage](/services/blocked-drains/), run a CCTV survey to show you exactly what is going on, and advise on liability. If it turns out to be South West Water's responsibility, we will tell you exactly what to report to them and how.

      <title>Drain Jetting vs Drain Rodding — Which Is Right for Your Devon Property?</title>
      <link>https://tavistockplumber.co.uk/blog/drain-jetting-vs-drain-rodding-devon/</link>
      <guid isPermaLink="true">https://tavistockplumber.co.uk/blog/drain-jetting-vs-drain-rodding-devon/</guid>
      <description>Two methods. Very different results. Here&apos;s what the difference between drain rodding and high-pressure jetting means in practice for Devon homeowners.</description>
      <content:encoded><![CDATA[When a drain blocks, there are two main clearance methods: drain rodding and high-pressure jetting. The one you use matters — and using the wrong method can mean the problem comes back within weeks.

## Drain Rodding

Drain rods are flexible fibreglass rods screwed together end-to-end and pushed manually into the drain from an inspection point. The engineer uses a rotating motion to break up or push the blockage along the pipe.

**When rodding works well:**
- Soft blockages — toilet paper, leaves, accumulated silt
- Blockages close to an accessible inspection point
- Older clay pipe drainage where the pipe may not be in good condition (high-pressure jetting can cause further damage in badly deteriorated pipes)
- Simple one-off blockages with no history of recurrence

**Limitations:**
- Cannot scour grease and fat from pipe walls
- Will not remove root intrusion — breaks it up temporarily but doesn't eliminate it
- Does not clean the pipe, only clears the immediate blockage
- Suitable for blockages within 10-15 metres of an access point

## High-Pressure Drain Jetting

A jetting machine forces water at pressures up to 4,000 PSI through a flexible hose and specialist nozzle. Different nozzles are used for different blockage types:

- **Rotating nozzles** scour grease and scale from pipe walls, leaving the pipe clean rather than just passable
- **Root-cutting nozzles** have hardened steel blades that cut through root intrusion and flush the debris out
- **Forward-cutting (penetrating) nozzles** push ahead of the jet to break up solid compacted blockages before the rotating head clears the walls
- **Warthog nozzles** rotate in a way that gives maximum wall contact, used for heavy grease accumulation in commercial or domestic kitchen drainage

**When [drain jetting](/services/drain-jetting/) is the right choice:**
- Recurring blockages that keep coming back despite rodding
- Grease, fat, and scale build-up in kitchen drain pipes
- Root intrusion in older Devon clay pipe drainage
- Longer drain runs where the blockage is far from the access point
- Preventive maintenance — jetting leaves pipes substantially cleaner than rodding

**Limitations:**
- Not suitable for pipes in very poor condition (should be assessed by CCTV first)
- Requires proper access for the jetting equipment

## When to Get a CCTV Survey Before Either Method

If a [CCTV drain survey](/services/cctv-drain-survey/) shows a partially collapsed pipe section, high-pressure jetting can make the damage worse. In Devon's older housing stock — Victorian clay pipe drainage is common across Tavistock, Okehampton, and Launceston — a recurring blockage in the same section of pipe usually means either root intrusion or displaced joints. A CCTV survey before clearing tells you whether to jet or whether to repair first.

The rule of thumb we use: if a drain has blocked more than twice in twelve months at the same point, run a CCTV survey before the next clearance. The cost of the survey is almost always less than the cost of an emergency clearance later.

## The Rural Devon Context

In older Devon properties — stone farmhouses, Victorian terraces, and properties with clay pipe drainage — drain rodding is often used first for speed, but [high-pressure jetting](/services/drain-jetting/) is almost always the right long-term solution. Rural properties with root intrusion around their pipework (particularly those with mature hedgerow trees, ash, and oak near the drainage run) benefit most from jetting.

Dartmoor properties often have simpler drainage runs but are more likely to have private drainage systems — septic tanks and soakaways. Blockages in private systems require different assessment than mains-connected properties; a CCTV survey is particularly valuable before any clearance attempt in properties where the drainage layout is unknown.

## Devon Case Study: Recurring Blockage in an Okehampton Terraced House

A homeowner in Okehampton had their kitchen drain rodded clear twice in eight months, with the blockage returning each time within six weeks. When we attended, we carried out a CCTV survey before any clearance attempt.

The camera showed a section of clay pipe with root intrusion from a mature ash tree in the rear garden, combined with a build-up of grease on the pipe walls. The roots had created a fine mesh that trapped grease and silt, which gradually built back up after each rodding.

We cleared the blockage with a root-cutting jetting nozzle, followed by a rotating scour nozzle to clean the pipe walls. The root mass was flushed out and the grease layer removed. No further blockages in over nine months.

## Cost Comparison: Rodding vs Jetting in Devon

Drain rodding as a standalone service typically costs £80–£130 depending on access and the nature of the blockage. High-pressure [drain jetting](/services/drain-jetting/) is usually £130–£200 for a standard domestic drain, though commercial kitchen drain jetting costs more due to the scale of grease accumulation. A CCTV survey is typically £120–£250.

For a straightforward first blockage, rodding is a proportionate first step. For any recurring problem, jetting plus a CCTV survey is almost always cheaper over the 12-month period than repeated rodding callouts.

## How to Prevent Recurring Drain Blockages

The most effective prevention steps for Devon homeowners:

- **Kitchen drains:** Pour a kettle of boiling water down the kitchen drain once a week. It is not a substitute for professional clearing, but it slows grease accumulation on pipe walls significantly.
- **External gullies:** Clear leaf debris from external gully covers in autumn. In Devon, where mature hedgerow trees shed heavily in October and November, blocked external gullies are a seasonal problem.
- **Tree proximity:** If you have a large ash, oak, or willow within 10 metres of your drainage run, a CCTV survey every 3-4 years is a reasonable preventive measure. Root infiltration is much cheaper to clear before it becomes a complete blockage.
- **Fat and grease:** Never pour cooking fat, oil, or grease down the kitchen sink. Collect it and dispose of it in your general waste bin.

We carry both rodding equipment and jetting machines on all call-outs, so we can choose the right method after assessing the blockage.

      <title>What Is a Rayburn and Can It Heat Your Devon Home?</title>
      <link>https://tavistockplumber.co.uk/blog/what-is-a-rayburn-devon-heating/</link>
      <guid isPermaLink="true">https://tavistockplumber.co.uk/blog/what-is-a-rayburn-devon-heating/</guid>
      <description>Rayburns are found in Devon farmhouses and rural cottages throughout the Tavistock and Okehampton area. Here&apos;s what you need to know about owning, running, and servicing one.</description>
      <content:encoded><![CDATA[If you have moved to a rural property in Devon — particularly in the Tavistock area, the Tamar Valley, or on the Dartmoor fringe — there is a reasonable chance you have inherited a Rayburn. These range cookers are a fixture of West Devon and east Cornwall farmhouses, and they are quite different from anything you will find in a town property.

## What Is a Rayburn?

A Rayburn is a range cooker manufactured by Aga Rangemaster that provides three functions from a single appliance: cooking, central heating, and domestic hot water. Like an AGA, it runs continuously rather than being turned on and off. It heats up from a central flue and distributes warmth throughout the property via a central heating circuit.

Rayburns can run on oil (most common in Devon), LPG, natural gas, or solid fuel (wood or coal). Oil models — which use a Wallflame or pressure jet burner — are by far the most common in rural Devon where mains gas is not available.

## Fuel Types: Which Is Most Common in Devon?

**Oil Rayburns** are the dominant type across rural Devon and east Cornwall. They burn 28-second heating oil (the same fuel as domestic oil boilers), delivered by tanker and stored in an oil tank, usually at the side of a barn or outbuilding. Oil Rayburns use either a Wallflame burner (an older, quieter design common in models from the 1960s to 1990s) or a pressure jet burner (more common in later models and more efficient but noisier). All oil Rayburn work must be carried out by an OFTEC-registered engineer.

**LPG Rayburns** are found in properties without mains gas or an oil tank, typically using a large LPG cylinder or a small buried tank. LPG is more expensive per kWh than oil but more convenient if the alternative is installing a 1,000-litre oil tank.

**Solid fuel Rayburns** are the oldest type and still found in some historic Devon farmhouses. These burn wood or coal and require daily attention — loading, ash removal, and flue checking. They have no automatic controls. Running costs can be low if you have access to timber, but they are labour-intensive.

## Why Rayburns Are Common in This Area

Much of the housing in the Tavistock area was built before mains gas arrived in Devon — and some rural properties have never had it at all. A Rayburn was, for generations, the practical solution: one appliance that cooks and heats the whole property from a single oil tank in the yard.

The running cost of a Rayburn on oil is higher than a modern condensing boiler, but the warmth they create — particularly the ambient radiant heat in the kitchen — is something many Devon homeowners value. Many rural properties would require significant modification to install a conventional boiler heating system, making the Rayburn the right long-term choice even today.

## Running Costs: Rayburn vs Modern Condensing Boiler

This is the most common question from people inheriting a Rayburn. The honest answer: a Rayburn on oil is more expensive to run than a modern A-rated condensing gas boiler, but often comparable to or cheaper than an older oil boiler system, because the Rayburn provides cooking alongside heating and hot water.

A typical oil Rayburn uses around 3,000–4,500 litres of oil per year for a medium-sized Devon farmhouse. At current prices (around 75–85p per litre in Devon in 2026), that is £2,250–£3,825 annually. A modern condensing oil boiler for the same house would typically use 1,800–2,500 litres for heating and hot water, saving on fuel — but you would still need to run a separate range cooker.

The full comparison depends on how much you value the cooking function, the ambient kitchen warmth, and the simplicity of one appliance versus two. Many Devon homeowners with working, well-serviced Rayburns find the overall economics are reasonable when all three functions are included.

## Annual Servicing

Rayburns require annual servicing. During a [Rayburn service](/services/rayburn-aga-service/), an engineer will:

- Check and clean the burner and combustion chamber
- Inspect the flue and ensure the draw is correct
- Measure combustion efficiency
- Check the heat exchanger for leaks or deterioration
- Test all safety controls
- Advise on any parts showing wear

Without annual servicing, efficiency drops steadily, fuel consumption rises, and the risk of burner failure or flue problems increases. A well-maintained Rayburn will typically last 30-40 years. A neglected one may fail within 15.

## Common Rayburn Faults and What They Mean

**Burner won't light or keeps cutting out.** The most common cause is a dirty or worn burner nozzle. In pressure jet models, the nozzle atomises the oil into a fine spray — when it becomes partly blocked, combustion is incomplete and the boiler locks out. A service resolves this. If locking out becomes frequent between services, the nozzle may need replacing sooner than the annual cycle.

**Reduced heat output.** If the Rayburn feels less hot than usual and fuel consumption has not dropped, the heat exchanger may be accumulating scale or soot deposits. This is resolved during the annual service, but if it develops between services, it usually indicates the combustion settings need adjustment.

**Flue drawing poorly.** In Devon's older farmhouses, flue problems are often caused by debris accumulation (particularly in autumn when birds can nest in unused flues), deteriorated flue liner, or — in unusual cases — the flue being overshaded by a new extension or tree growth that changes the airflow. A heating engineer can assess this.

**Oil smell.** Any oil smell from the Rayburn area should be investigated. It can indicate a leaking oil line, a faulty burner seal, or incomplete combustion. Do not ignore an oil smell.

## When to Replace Rather Than Service

A Rayburn that has been well maintained can serve a Devon property for decades. The signs that replacement is becoming the better option:

- Heat exchanger cracked or leaking (often the most expensive single repair)
- Repeated burner failures in a short period, indicating the burner assembly is worn out
- The Rayburn is pre-1980 and has never been upgraded — older models are significantly less efficient and spare parts are becoming scarce
- You are converting the property to a different heating system (mains gas connection, heat pump) and the Rayburn will no longer be the primary heat source

For replacement, contact the AGA Rangemaster service network or a [heating engineer](/services/heating-engineer/) with Rayburn experience. We can advise on whether to replace like-for-like or transition to a conventional oil boiler system.

## Who Services Rayburns in Tavistock?

This is a genuine gap in the local market. Chamings Plumbing — the main incumbent Tavistock plumber — has a Rayburn page and attracts around 10 visits per month for it. Beyond that, there is very little local provision.

We [service Rayburns and AGAs](/services/rayburn-aga-service/) across the Tavistock area and rural Devon, including remote farms and properties on Dartmoor National Park where access requires forward planning. If you have a Rayburn that is overdue for service, or one that is running inefficiently, request a quote online.]]></content:encoded>

      <title>Signs Your Boiler Needs Replacing — Devon Homeowner&apos;s Guide</title>
      <link>https://tavistockplumber.co.uk/blog/signs-your-boiler-needs-replacing-devon/</link>
      <guid isPermaLink="true">https://tavistockplumber.co.uk/blog/signs-your-boiler-needs-replacing-devon/</guid>
      <description>Boiler repair or full replacement? It&apos;s the question every Devon homeowner faces sooner or later. Here&apos;s how to tell the difference — and when replacing saves money in the long run.</description>
      <content:encoded><![CDATA[At some point, every boiler has to be replaced. The question is when — and whether repair still makes sense at that point. Getting this wrong is expensive either way: paying for a major repair on a boiler that fails again six months later, or replacing a boiler prematurely that had plenty of life left.

Here is how our Gas Safe registered engineers assess whether a Devon boiler is worth repairing.

## Age Is the Starting Point

Most modern condensing boilers have a working life of 10-15 years with annual servicing. Beyond 15 years, the probability of major component failure rises significantly. If your boiler is 12 years old or more, the repair-versus-replace calculation starts to shift.

That said, age is not the only factor. A 15-year-old boiler that has been annually serviced and has never had a significant repair can still have years of life left. A 10-year-old boiler that has been neglected may be near the end.

## The Repair-to-Value Calculation

A rough guideline used across the industry: if the repair cost is more than half the cost of a new boiler installation, replacement is usually more cost-effective. This is particularly relevant when:

- The heat exchanger needs replacing (often the most expensive single repair)
- The boiler needs a gas valve replacement
- Multiple components are failing at the same time

For a new condensing combi boiler installed in a Tavistock or Okehampton property, installed cost is typically £1,500-£2,500 depending on the model and complexity. If a repair quote is above £800-£1,000, the calculation shifts firmly towards replacement.

## Warning Signs That Suggest Replacement

**Frequent breakdowns.** If you have had two or more significant repairs in the last two years, the boiler is telling you something. Parts failures rarely come in isolation — when one component wears out, others are usually close behind.

**Yellow or orange flame.** A healthy gas boiler burns blue. A yellow or orange flame indicates incomplete combustion and the possible production of carbon monoxide. This is a safety issue requiring immediate attention. An engineer may be able to adjust the combustion, but in an older boiler this is often a sign of serious heat exchanger deterioration.

**Carbon monoxide alarm triggering.** If your CO alarm has triggered, get out of the property and call the Gas Safe emergency line. Do not assume a reset solves the problem. A boiler producing CO needs thorough investigation — and in many cases, replacement.

**Constantly losing pressure.** A boiler that needs topping up every few weeks has a leak somewhere. Sometimes this is a simple valve repair. In older boilers, it often indicates a failing pressure vessel or heat exchanger seam — neither of which is cheap to fix.

**Significant rise in energy bills.** Boiler efficiency drops as components age. A condensing boiler that was 90% efficient when new may be running at 75-80% after ten years of use. If your bills have risen without a change in usage, the boiler is a likely cause.

## Reading Your Boiler's Fault Codes

Modern boilers display fault codes when they lock out. These are not always obvious, but they are useful information for the attending engineer. Common codes that suggest wear rather than a simple fix:

- **H1 / F1 / EA fault codes (varies by brand):** typically related to heat exchanger overheat — can indicate scale build-up, poor flow rate, or a failing component
- **Ignition lockout codes (e.g. Vaillant F.75, Worcester E9):** repeated ignition failures suggest either a worn igniter or pump issues
- **Low pressure codes:** if the boiler requires regular filling to maintain pressure, the cause needs investigating, not just topping up

When you call for a [boiler repair](/services/boiler-repair/), noting the fault code before the engineer arrives helps them arrive with the right parts.

## New Boiler Cost Guide for Devon Properties

Installed costs for a replacement boiler in the Devon area (2026):

| Boiler type | Installed cost (approx) | Notes |
|---|---|---|
| Gas combi (mid-range) | £1,760–£2,400 | Most common in Tavistock and Okehampton terraces |
| Gas combi (premium) | £2,400–£3,200 | Longer warranty, better efficiency |
| Oil condensing combi | £2,800–£3,955 | Rural Devon properties without mains gas |
| Oil regular boiler + cylinder | £3,200–£4,500 | Larger rural properties, multiple bathrooms |

These figures include supply, installation, flue adaptation, and commissioning. They do not include power flush (£300–£500 if the system requires it before a new boiler is installed) or significant pipework alterations.

## The Devon Rural Property Consideration

For properties with oil boilers — common across rural Devon, Dartmoor, and the Tamar Valley — the calculations are slightly different. Oil boilers tend to have longer working lives than gas boilers, partly because the servicing regime is more rigorous (OFTEC registration is required for all oil work). An oil boiler in good condition can run for 20+ years.

Modern oil condensing boilers are significantly more efficient than older pressure jet or Wallflame models. If you have a pre-2000 oil boiler, the efficiency uplift from replacement (from around 65-75% to 90%+) can justify replacement on running cost savings alone, even if the boiler is still functioning.

## Landlord Requirements in Devon

Landlords in Devon have a legal obligation to have gas appliances — including boilers — serviced annually by a Gas Safe registered engineer, and to provide tenants with a copy of the Gas Safety Record (CP12 certificate) within 28 days of the check. Failure to do so is a criminal offence.

For a boiler that is failing regularly or approaching end of life, replacement before a tenancy begins is almost always the right commercial decision. Tenant callouts for boiler failures in winter are disruptive, expensive at emergency rates, and in the worst case can lead to local authority intervention if the property becomes uninhabitable.

We carry out annual [boiler services](/services/boiler-service/) and issue Gas Safe certificates on the day across the Tavistock service area.

## What We Recommend

When we attend a boiler fault in Tavistock, Okehampton, Launceston, or surrounding rural Devon, we will always give you an honest assessment. If we believe replacement is more cost-effective than repair, we will say so — and if [boiler repair](/services/boiler-repair/) is the right call, we will say that too.

We do not earn more from recommending replacement over repair. Our interest is in giving you accurate advice so the problem is properly resolved.

      <title>Emergency Plumber in Devon — What to Do Before the Engineer Arrives</title>

      <description>A plumbing emergency in a rural Devon property can feel isolating. Here&apos;s a clear guide to what to do in the first few minutes — before the engineer arrives.</description>
      <content:encoded><![CDATA[A plumbing emergency is stressful enough. In a rural Devon property — where help may take an hour or more to arrive — knowing what to do in the first ten minutes can significantly reduce the damage.

## Burst Pipe

**Step 1: Turn off the water.** Your main stopcock is usually under the kitchen sink, in an airing cupboard, or where the water main enters the property. Turn it clockwise to stop the water. If you cannot find it, there is an external stop tap in a small chamber in the pavement or driveway outside — this can also be turned off with a stop tap key.

**Step 2: Drain the system.** Turn on your cold taps throughout the house to drain any water remaining in the system. This reduces pressure and the amount of water that can escape.

**Step 3: If near electrics, turn off the power.** A pipe burst near a consumer unit, socket, or lighting circuit is a serious hazard. Turn off the main switch at your fuse box.

**Step 4: Contain the water.** Put down towels and buckets. Move electronics, rugs, and other valuable items away from the water.

**Step 5: Document.** Take photos before you start any clean-up — you may need them for a home insurance claim.

## Finding Your Stopcock: Devon Property Types

The location of your main stopcock varies significantly by property type. In Devon's older housing stock:

**Victorian terraces (Tavistock, Okehampton, Launceston town centres):** The stopcock is usually under the kitchen sink or in the downstairs bathroom. In some older terraced properties, it is behind a timber panel in the understairs cupboard or at floor level in the hallway near the front door.

**Stone farmhouses and longhouses (Dartmoor fringe, Tamar Valley):** The water main often enters through the stone floor of a utility room or scullery at the rear. The stopcock may be at a very low level, partially obscured by a fitted unit, or in a separate boiler room or dairy. Some rural properties have the stopcock in an outbuilding near the water meter.

**Modern detached houses (housing estates around Tavistock):** Usually under the kitchen sink, but sometimes in an underfloor void or at the side of the property in a small external housing.

If you cannot find the internal stopcock in an emergency, use the external stop tap. This is a square-ended fitting in a small plastic or metal cover set into the ground at the front of your property boundary, usually near the pavement edge. A stop tap key (available from any hardware shop for around £3) turns it — or improvise with a flat-bladed screwdriver in the slot.

## Frozen Pipes: A Specific Dartmoor and West Devon Risk

Properties on the edge of Dartmoor and in exposed rural Devon locations are at greater risk of frozen pipes than urban areas. Dartmoor is statistically the coldest part of South West England. Exposed pipes in unheated outbuildings, garages, loft spaces, and external walls are particularly vulnerable during cold snaps.

**Signs of a frozen pipe:** No water from a tap, no flow from a shower, or a partial flow with unusual resistance. If you can hear water running (from a dripping overflow or icemaker) but nothing comes out of taps, a frozen pipe is likely.

**What to do:** Do not use boiling water on frozen pipes — the rapid temperature change can crack them. Use a warm (not hot) wet cloth wrapped around the pipe, or a hair dryer on its lowest heat setting. Start from the tap end and work back towards the stopcock. If the pipe is hidden in a wall or floor, this is a job for an [emergency plumber](/services/emergency-plumber/).

**Prevention for next winter:** Lag exposed pipes in loft spaces and outbuildings before November. Maintain at least 13°C (55°F) in the property even when away. Know where your stopcock is before you need it.

## Boiler Breakdown — No Heat or Hot Water

If the boiler has simply cut out, check the following before calling:

- **Pressure:** Most combi boilers need to be between 1 and 1.5 bar at rest. If the gauge reads below 0.5 bar, the boiler may have shut off due to low pressure. Topping up the pressure via the filling loop may restore operation temporarily.
- **Thermostat:** Check that the room thermostat and programmer are set correctly and that there is no battery failure.
- **Gas supply:** Check that other gas appliances in the property are working. If not, contact your gas supplier.
- **Error code:** If the boiler has a fault display, note the error code before calling us — it helps the engineer prepare for the most likely cause.

If the flame has gone out and the boiler will not relight, or if there is a smell of gas, do not attempt to relight it. Leave the property and call the Gas Emergency line (0800 111 999) immediately. Request a [boiler repair](/services/boiler-repair/) once the property is declared safe.

## Gas Smell

If you can smell gas:
1. Do not operate any electrical switches.
2. Open all windows and doors.
3. Leave the property immediately.
4. Call the Gas Emergency Service: 0800 111 999 (free, 24 hours).
5. Do not re-enter the property until it has been declared safe.

## Blocked Drain Causing Overflow

If a [blocked drain](/services/blocked-drains/) is causing sewage or waste water to overflow inside the property, try to identify and stop the source:
- Do not flush toilets or run water into affected drains.
- If the overflow is from a ground floor toilet, check that the soil stack access point (if there is one) is not blocked.
- Keep people and pets away from sewage overflow — it is a health hazard.

## What to Tell the Emergency Plumber When You Call

Having this information ready speeds up the response significantly:

- Your postcode or full address (including village name for rural Devon properties — postcodes can cover large areas)
- Whether the water is still running or has been isolated
- Where the problem is (loft, ground floor, external, etc.)
- What has already been done (stopcock turned off, power isolated, etc.)
- Whether there is any electrical risk

For Dartmoor and rural Tamar Valley properties, mention if the access road has any weight restrictions or if there is a particularly narrow section — our engineers plan their route accordingly.

## What an Emergency Callout Costs

We provide a fixed price before any work starts — no surprises when the invoice arrives. Emergency call-outs attract a higher rate than planned work, which is standard practice. Typical ranges for common emergency jobs in Devon:

- Burst pipe isolation and temporary repair: £150–£250
- Emergency drain clearance (toilet blocked, sewage overflow): £130–£200
- Emergency boiler restart (fault code, frozen condensate): £100–£180
- Major leak investigation and first-fix repair: £180–£350

These figures are for the emergency attendance and first-fix only. Follow-up work (permanent pipe replacement, full drain survey) is quoted separately.

## When to Call Us

All of the above situations qualify for [emergency attendance](/services/emergency-plumber/). We cover the full 20-mile radius from Tavistock and aim to provide an honest estimated arrival time when you contact us. Rural properties on Dartmoor or in the Tamar Valley will have longer arrival times than town-centre addresses — we will always be upfront about this.

Request an emergency attendance online and we will confirm coverage and arrival time immediately.]]></content:encoded>
