What Sludge Does to a System

Sludge is rust and debris that settles inside radiators and pipes. It blocks the flow, so the bottom of a radiator stays cold while the top is hot. The boiler then works harder to heat the house, which costs more to run and wears the pump out sooner.

What Happens on the Day

We connect a pumping unit to the system and push cleaning chemicals through it at speed, radiator by radiator. The dirty water goes out to drain until it runs clear. A magnetic filter and inhibitor go in at the end to slow the build up returning.

When a Flush Is Not the Answer

If only one radiator is cold, it may just need balancing or bleeding. If the pipework is badly corroded, flushing can open up pinholes that were already there. We check the system first and say honestly whether a flush will help, because there is no point paying for one that will not.

Frequently Asked Questions

How long does power flushing take in a Godalming home?

Most homes take between four and eight hours, depending on how many radiators there are and how bad the sludge is. Large or heavily blocked systems can run into a second day. We give you a time estimate with the free quote so you can plan around it.

How do I know if my Godalming heating system needs a power flush?

Cold patches at the bottom of radiators, dirty black water when you bleed them, noisy pipes and a boiler that keeps cutting out are the usual signs. If the house takes much longer to warm up than it used to, that points the same way. We test the system before quoting.

Will power flushing damage old pipework in an older Godalming property?

It can if the pipework is already corroded thin, which is why we inspect the system first. On some older properties we recommend a gentler chemical clean instead. You get an honest answer before any money changes hands, not after the flush has started.
