Hi Forum, not posted on here for years!!! Now back with a question.
I have an Ideal Classic RS Sealed System boiler. It is about 13 years old.
Recently the pressure has been dropping on the gauge. This is due to the air valve on the Expansion vessel being a little leaky. Nothing dramatic but it looses pressure over time and needs constant pumping up. The diaphram seems OK as no water comes out of the valve. No drips from pressure pipe.
I tried to replace the valve insert as per a car or bike tyre but it would not come all the way out. Now the valve is more leaky than ever
It seems like it should unscrew but not all the way.
Any ideas? It seems a shame to replace a perfectly good expan vessel at £70 for the sake of a part that cost 70 pence.
Thanks In Anticipation
