Hi all,
looking for some advice. My pressure on the system rises to 3 bars every time the heating kicks in. then the release valve goes and dumps water outside (a very small trickle). there is no similar effect from the hot water however.
I have just disconnected the filling loop and each time the boiler loses all pressure (as well as spraying my walls! there is a tap fitted to the cold mains end of the loop but seeming nothing to keep the boiler end of things pressurized on removal of the loop (from what i read i am not sure this is normal)
i therefore cannot test if the continual rise in pressure when i activate the central heating is due to a faulty filling loop valve (this has recently begun to drip water at a very slow rate too)
or is it something more sinister like the expansion vessel? i know this may similarly generate the same symptoms. as it only happens maybe 30-40 seconds after the heating comes on i wondered if this was more likely the cause?
My boiler instructions state that replacing this requires the removal of the boiler from the wall and full disconnection of gas and water(that sounds extremely expensive before the cost of parts)
would hate to call some one out to find it was a £4 tap i could of bought from a diy shop!
any advice as to which is more likely?
Thanks
