Our process

Inspect

We assess symptoms and isolate the likely blockage point. Furthermore, we lift the nearest manhole or use CCTV access to confirm the location before any clearance work begins.

Resolve

We clear and clean drains using the right method for the issue. Therefore, you avoid both the under-clearing of repeat call-outs and the over-clearing of unnecessary work.

Prevent

We provide practical recommendations to reduce repeat callouts. As a result, our customers typically see year-on-year reductions in drainage costs after their first visit.

Power Flush — frequently asked questions

What is the difference between a combi boiler and a system boiler?

A combi (combination) boiler provides central heating and hot water on demand from a single unit — no separate cylinder or cold water tank needed. It is ideal for smaller properties with one bathroom. A system boiler works with a separate hot water cylinder but no cold water tank, making it better suited to larger homes with multiple bathrooms. Heat-only (conventional) boilers work with both a cylinder and cold water tanks — common in older Devon properties, particularly those with Rayburn or AGA-style heating.

What does a heating engineer do versus a plumber?

A plumber handles cold and hot water systems — pipes, taps, tanks, and drainage. A heating engineer specialises in central heating systems, boilers, radiators, and underfloor heating. Many plumbers in Devon are dual-qualified, covering both. Our engineers are Gas Safe registered and handle both disciplines, so you do not need to call two separate contractors for boiler and plumbing issues.

What is a power flush and how much does it cost?

A power flush forces a high-pressure chemical solution through your central heating system to remove sludge, scale, and rust. This improves heating efficiency and extends boiler life. Signs you may need one include cold spots on radiators, noisy boilers, and slow-heating rooms. A power flush on a typical 8-10 radiator system in Devon costs approximately £300-£500 and takes 4-6 hours.
