It is not a new installation, nearly 5 years old and has only recently started the banging, if remove the electronic bit and turn the valve manually it bangs / hammers but less now mains pressure is lower. Has not done it since turned up the room stat to max. But when turning back to normal temp...
yes and just been playing with thermosatat downstairs which brings it in and out so guess it just regulates flow and it is pressure i need to sort to eliminate banging
may have the wrong terminiology for valve, but it is electronic in the airing cupboard and appears to be regulating flow from main supply to tank via primary inlet to storage tank
Hi, new on here but have a valve which appears to be in the primary feed to the hot water storage tank which opens / closes every 2-3 min's clunking with pressure when closing. I have turned the main pressure down to quiten it a little but would welcome any ideas why does it keep operating so often?
