A few months ago I had a problem with the diverter valve in my boiler (an old but well-maintained Worcester Bosch). The plumber came to repair the boiler but after taking a sample of not more than a few drops from the valve in the boiler decided that the system had sludge and would not proceed until I had had a power flush.
In the end, I decided to replace the boiler and, in the process, did have a power flush. The company that did the power flush told me that the system was clean to start with. Who do you believe?
