    I have a system boiler and have recently had some building work completed which required the mains and the kitchen supplies to be moved. The plumber that carried out the work advised that he has replaced like for like with the pipe work so that should no cause any issue.

    Of late the pressure/flow from our taps has been pitiful as well as from both showers and the bath. It is also effecting the toilet cistern filling and if any 2 outlets are being used at the same time the water coming out is minimal at best.

    I have a water softener which i have isolated but this has had no effect. I had a plumber visit a few days ago who recharged the expansion vessel as the pressure had dropped. This is now back up to 3 bar (as prescribed by the cylinder instructions) but a strange vibration has now been caused when using some but not all taps and it sounds like a loud fog horn that carries on after the tap has been shut off.

    I have contacted the plumber again who is due to come out, he has said that maybe the flow balancer has become clogged and should be cleaned out or may even now be faulty.

    The only tap that works properly is the kitchen cold water supply which has high flow and pressure, i assume this comes straight from the mains inlet under the sink. We have had great flow and pressure prior to this issue. Does anyone have any other thoughts that could be causing the drop in flow/pressure.

    Thanks

    sounds like it could be dirt in a strainer etc if all the other cold taps and toilets are off the balanced cold

    but i would go round and clean any mesh / strainer that you could find / he can find etc

    but he shouldnt of let any dirt into the system in the first place

    As Shaun says if you have a balanced cold supply from a combination valve and unvented hotwater then it could quite possibly be the mesh strainer partily blocked . Kop

    Had a similar problem recently and it turned out to be the pressure reducing valve.
