Good Morning,
We've relatively recently moved house and have very noisy radiators upstairs, to the point that they'll happily wake us up.
Had a plumber out to look at the issue today who said something along the lines of "I'm a very experienced plumber and I've never heard anything like this before". I'd done some diagnostics before calling them out and noticed that the TRV's are on the return pipes rather than inlets.
The moment I mentioned this to him he seemed to decide that all the TRV's upstairs should be replaced and that "might" solve the problem. Suffice to say I'm not bowled over with confidence at the level of diagnosis that was performed.
I've read previously about single direction TRV's causing a hammering type noise when on the return pipes. The noise appears to occur when either of the two radiators (out of four upstairs + towel rail) have the TRV head anything other than closed (including removed entirely so presumably fully open). The noise only stops when both valves are fully closed.
Are we barking totally up the wrong tree here? I appreciate that replacing the TRV's is a fairly cheap job, at least in terms of parts, but as I said, I've not got much confidence in the level of diagnosis that was conducted!
Opinions welcome
