Hello all I know most regulars here will be bored to death with questions like this but despite a search I cannot find any questions/ answers to fit my problem. There is a banging/knocking noise coming from my hot and cold pipes when absolutely nothing is turned on. It has been going on now for a couple of months. It happens randomly and I cannot re-create it by turning anything on or off. I was fitting a new bathroom suite and towel radiator recently so had the supply turned off at the main stopcock and had the CH (combi) drained but the noise was still there. I just can't work this one out. Normally I would blame the neighbours (semi detatched) but the noise sure sounds like it's coming from my pipes. Any suggestions welcome TIA
