Step three, inhibitor dosing, radiator rebalancing and final performance tests, backed by 14 years' experience and a 12-month workmanship guarantee.

Power Flushing Done Right

How It Works

01

System Survey

We inspect the boiler, pump, radiators and pipework to locate sludge build-up and assess access for flushing.

02

Controlled Flush

Using professional power-flushing equipment we circulate high-flow water and cleaners to dislodge and remove debris.

03

Inhibit and Test

We fit corrosion inhibitor, rebalance radiators, run performance tests and provide a completion report with recommendations.

Extend boiler and radiator life

Local, reliable service

Based in Shevington and serving a 20-mile radius, SDW offers fast response, 14 years' experience and a 12-month workmanship guarantee.

What power flushing does, in plain terms, is strip out the black iron oxide, sludge and limescale that builds up in heating systems, especially in older properties and systems with cast-iron radiators. That sludge restricts flow, causes cold spots and forces the boiler and pump to work harder, shortening component life and increasing call-outs.

How SDW delivers it. We start with a diagnostic survey, then connect our high-flow flushing unit and use controlled water flow with cleaning agents to flush debris to drain. After clearing the system we add a long-life inhibitor, rebalance radiators and run a full performance check. Work is completed by Gas Safe Registered engineers, backed by 14 years' local experience and a 12-month workmanship guarantee. To arrange a survey call 07582 732842 or email sdw82@hotmail.co.uk.

Frequently Asked Questions

Most power flushes are completed in one day for typical domestic systems, but time depends on system size, level of sludge and access. We give a clear time estimate after the initial survey and keep the property tidy throughout the job.
