Hi,
Have a really annoying problem with a noise in the cold supply. It is just a loud single bang which occurs when either the downstairs toilet is flushed, or when the washing machine or dishwasher are being used.
I can get rid of the problem when I restrict the flow of water through the cold supply stop cock, but this then reduces the water pressure in our shower as we have a combination boiler - so no cold water tanks in the loft or anything like that - just everything fed from the mains.
The toilet, the washing machine and dishwasher all have isolater valves and I have tried to restrict the flow of water by closing those of partially. However this then has the effect of making a loud rushing noise for the water for the pipes which lasts for the whole time that the toilet etc is filling up.
Having searched the forums it seems to be suggested that a pressure reducing valve or a shock arrester could cure this problem. If so do I need to place one on the supply to every item which causes the loud bang.
Thanks for any input.
