Noisy old boiler?
My son has an old wall hung boiler.
It is fully pumped and it works fine.
Trouble is that when the boiler lights, it is ok, but when it is shutting off, having made the thermostat etc, it emits a noisy groaning noise, from either a gas or water valve( we are not sure) Can we stop this without too much trouble/ expense?
