The OP
Hi All,
This is my first post on the forum, and I'd be very grateful for your thoughts on a problem we have had for a month, and which we have spent several £100s on, with no success.
Despite visits from 3 plumbers/engineers, we cannot get rid of a loud screeching/groaning noise occuring in our plumbing, which seems to emanate from, or near, or Megaflo unvented indirect cylinder. We have almost run out of ideas!
When the noise is loud, the pressure gauge wobbles slightly. But it never exceeds 1.4 bar, even when noise is at loudest.
The pressure relief and pressure reducing valves have been changed, and a shock arrester installed. All to no success. A heatrae sadia engineer said it wasn't the tank (though it really sounds like the noise comes from the megaflo, especially when you put your ear to it). He suggested we have the two zone valves looked at.
Before I spend yet more money- has anyone any ideas?
Many many thanks.
