Hi Rob
Sorry I haven't been looking for a day or so, yes its the copper pipe over the cistern. The boiler side heating the water and feeding the radiators appears to be working fine. Any ideas? Please
I am at the moment cleaning the boiler system with Fernox ds40 and all seems to be good, but I have been here before. Is there anything I can use to clean the hot water side safely in case there is scale blockage.
the pipe over the tank in the loft keeps running causing the tank to overflow. I have now turned off the water supply to the cylinder which has stopped it. Any ideas?
