Hi,
I'm new here and would greatly appreciate some advice. We recently had a combi boiler system put in our late 1960s semi - We used to have a gravity system with conventional boiler that was sited in the kitchen on the ground floor but the new combi boiler is now upstairs in the airing cupboard where the old immersion tank used to be and is adjacent to the bathroom. The new installation uses our old rads and a new rad with some new pipework.
We have quarter turn mixer taps on the kitchen sink downstairs and on the bath and bathroom wash hand basin upstairs. Since the installation, all taps - both hot and cold - clunk when we turn the taps off (and sometimes they clunk when they are turned on but to a much lesser extent, except for the hot tap on the kitchen sink which clunks more when turned off than when it is turned on). When the taps on the kitchen sink downstairs clunk shut it causes water hammer and reverberation in the toilet cistern upstairs. When the toilet is flushed and the cistern fills up it clunks shut and causes reverberation in the toilet cistern and water hammer. When any of the bathroom taps - both wash hand basin and bath, hot and cold - are turned off some water comes out of the instant shower situated over the bath and to a lesser extent some water comes out of the shower when the cold tap, but not the hot is turned off on the kitchen sink. We are guessing this is to do with the water pressure.
We called out the installers who told us that everything was down to water pressure and that we should turn down the main stop tap. They are refusing to do anything else even though that hasn't helped. We want to call another plumber out but are we right in thinking that this is going to be a process of trial and error? Where do we start? - With replacing the valve in the cistern with a Torbeck equalibrium valve or a Fluidmaster Quiet Float Valve (400UK074)? - We don't know as yet but we guess that current the valve in the cistern may not have had the restrictor inserted because the toilet was previously tank fed but is now mains fed. Would replacing the main stop tap help? - We read something about jumpers working loose in stop taps. And might a water hammer arrestor help and where should this be put? We don't know what our water pressure is, but could it be that we need to have a 'pressure reducing valve' put in near the main stop tap?
Many thanks for your advice.
