Anyone had a power flush? Was it successful? Any down sides? Extra leaks?
Was it expensive and did it take a whole day or a few hours?

Just had a new pump fitted and a power flush was recommended. Our central heating system was installed 40 or so years ago. The boiler was replaced 7 years ago and is regulalarly serviced.

We have used the same company for the last 20 years.

@menopausal bitch
Yes. Thanks that’s absolutely true. I should have described the cold patch better. Ii would be at the bottom of the radiator and rise in the centre a bit like a hillock. That’s the buildup of ‘sludge’.
