We've recently had a new combi system installed (Worcester Hi-Flow 550cvi), replacing an old cynlinder/tank system, and are now experiencing really loud noises under the floor upstairs when some of the taps in the house are on. The noise happens only with the taps on, and not all taps create it - we hear it with the hot and cold kitchen taps (but not fforrm a filter tap also in kitchen basin) and the hot tap only in the downstairs bathroom. Also happens when the upstaris bathroom sink mixer tap is on - no issues running bath or showers or other upstairs bathroom sink.
It's so loud that we don't use the kitchen tap when someone is asleep - not a long term option! We have also had several leaks over the last three weeks which is very worrying. We hae just moved into this house so we dont' know if the noise existed before (left message wiht previous owners).
The plumber who fitted the new system (great chackatrade ratings) says he has never expereinced this before and does not know what the problem is. He originally decided it was becasue the water pressure was too high form the mains (the water was ridiculously powerful, flying over the basins when taps on full), so he turned it down at the mains - noise disappeared but only for a few hours. After 4 days put the pressure back up. Now he wants to take up the floor upstairs to investigate the pipes but as we've just had the floors sanded and restored we are not keen to do this just as an experiment when he already admits he doens't know what's wrong. I'd really like to get a second opinion at this point or someone who recognises the issue with some good investigative leads not requiring major surgery which we can try first!
Thanks in advance for any help, much appreciated.
