Thanks oilhead & boilerdoktor,
oilhead:
- Actually I think that the previous owners would have said if they had a noise, obviously not before we'd bought the place but once all money is transferred and we've moved in why not? I had a long chat with him and he was very helpful with ideas and advice but swears they never had any noticeable noise - they did have carpets and we have restored the boards but it is sooo loud there is no way that they wouldnt' have heard it, though it might not have bothered them so much. Will never know for sure of course!
- No leaks on the pipework added as part of the install.
- I think that they tried turning down the stop tap (at least they tried various ways of reducing pressure to see if it stopped the noise - including turning the mains right down). Turning the mains right down stopped the noise for about an hour, then it was back albeit quieter but still very noticeable and the pressure was no use for a shower where it had been set to so not a workable aproach. Anytime the mains has been turned off or down the noise stops briefly and then returns.
- Cold pipe has a pressure reducing valve but I believe from other posts and a visit from another plumber that this is in the wrong place as the cold tees off before the PRV position.
@boilerdoktor:
Thanks for this advice, three really good leads for things to follow up on. I've just had the same advice from a few others about an expansion vessel (no water meter but not sure about the non return valve so will get this checked).
Hugely appreciate the input, advice and help so thank you...
