We have recently had a new Combi Boiler installed and it is losinig pressure.
The system has been installed for about a month now and the engineer had to come out to repressurise the system a couple of weeks after the install because the system was losing pressure, however the pressure has now dropped again and is currently at approx. 0.5 Bar when cold.
My question is this. Can worn out fiber washes on our house taps (between taps and piping) cause this drop in pressure?
In particular I have noticed one hot water tap where if I feel around the fixings below the tap there is a small amount of water present.
Any help is appreciated.
Thanks in advance
