Isolation valve leak

[sidsmith]

One of the isolation valves underneath my boiler has developed a leak, and the pressure drops regularly due to this

What's the best way to change it - drain down the primary system - and what type of valve can I fit - will a 22mm ball-o-fix compression swap be ok? Probably need to alter pipework slightly if new valve longer or shorter?

Thanks for your help all

Common fault on these boilers.

ok - worcester in general or just the junior?!

why do they leak?!

will the way i asked be ok to fit a new one or do i need a specific isoaltion valve replacement from them? i was going to pop down to screwfix and pick up a 22mm compression ball-o-fix ....?

I would recommend fitting an original part.

Don't restrict the flow.
