Question for a plumber

When I run hot water as tank refilling it sounds like a fog horn. It is hot water tank only we are not on gas and not part of central heating as storage radiators for heating. ?

our pipes used to play orchestral tunes and DH thought it was the pipes vibrating. He sorted it out by covering the pipes with insulation (like foam tubes). Not sure if your issue is the same but worth a look - we've been very quiet since (about 9 months ago since it was sorted out)

Might be time to replace the valve feeding the tank. They can do this...

If it's a normal open vented cylinder ( fed from a storage tank above) then it most likely needing a new washer in the ball valve of the storage tank (diaphragm type washer has expanded causing excessive mains pressure through the valve & subsequently the valve vibrates which is where the droning noise comes from. If it's a mains fed unvented hot water cylinder then the noise can be caused by a vibrating spring in the pressure reducing valve
