hello all, this is my first post and wonder if anyone can help with the above combi boiler problem. The boiler itself seems to work as it should ie hot water and radiators work OK, but after you turn off the hot water tap the boiler makes a rumbling noise for about 20 seconds which then stops. if you are close to the boiler its not very load but upstairs the noise is much louder. The more hot water you draw the longer the noise will last in 20 second cycles.
Ive also noticed that there is a steady drip from the outside pressure release pipe after the hot water has been on and that Ive had to top the system up to 1 bar about every 3 weeks. The pressure on the pressure dial never goes up into the red zone when water has been drawn or the radiators are on.
The only work that has been done on the boiler was a new diverter valve about 6 months ago, cost me a packet and the plumber soaked the carpet below the boiler. I dont think the noise was happening before then but then we had only been in the house a few months and still getting used to everything.
Could anyone please help me with this problem or know someone local to me who could fix the problem for us?
Gus
