Dear folks
I have got Gas storage water heater (dux prodigy) with noisy one way valve ,,,,,,,my case i have :
one way valve (the one with arrow) plus T head Stop Cock M/M.
I called two plumbers they quoted $400-$450 to replace it I feel (i could be wrong) over priced ?
My question would Duo valve a one way valve and isolation valve from AVG
suffice the noisy one way valve (the one with arrow) and T head Stop Cock M/M ??
Thx
