Any advice would be very much appreciated.
In a basement flat after increasing the water pressure (opening up the stop cock). When the washing machine stops or any tap is turned off there is a terrible noise in the pipes. Like a banging noise.
When the pressure is turned down the noise stops. However I need the increased pressure for the shower and taps.I know other flats in the block have their stopcocks fully open.
I read somewhere that the jumpers in the stopcock could be worn, and causing the problem.
Is it a case of having the stopcock changed or can the stopcock be serviced.
I also read that in some cases air chambers are needed around washing machines and dishwashers. knowing nothing about air chambers or plumbing could you advise if this is a big job or if the air chambers can be fitted anywhere else.
The local plumbers merchant said that there could also be air in the system and may need to be bled. I dont understand this as I would of thought the increased pressure would blow the air out.
I have checked that all the fittings are good and no pipes seem loose.
Could you please advise the cheapest and easiest solution.
Many thanks gravy
