SHRAEDER VALVE ON EXPANSION VESSEL

[Gregory12004033]

Good morning people.
Well i've found out why the pressure keeps dropping on my Worcester boiler and it turns out that its the shraeder valve thats leaking air on the expansion vessel.
Can anyone tell me if the valve alone can be replaced or has the whole expansion vessel got to be replaced
Many thanks
Greg

Valve can be replaced. Might not be easy to get it out of the vessel if it's in an awkward position though.

Go to a car spares or bike store and buy a new insert together with a valve removal tool. Cheap as chips.

this sort of thing would do it

Are all the valves universal?

Use the short series tyre valve rather than the one with the long spring - the threads are the same.

When you have put your new valve in. drain the water out of the boiler and leave the drain off valve open so that the water can be pushed out of the expansion vessel as you re-pressurise the vessel to no more than 1bar/14.5psi.
