Hello all,
Ive read alot of the forum today and cant quite see a scenario similar to mine so wondered if you would be kind enough to give your thoughts to this one...
We recently had a Worcester Bosch greenstar (combi) boiler installed. (ground floor) and it feeds the whole house via mains pressure alone which is fine.
We had a problem about a 2 months ago with a leak from the shower mixing value. So I had to dig into the upper landing wall to get to the hidden value. I ended up replacing both elbow values as it turned out that the threads of the ones that were fitted were not cut right so when we moved from a gravity one to a combi the increased pressure took advantage of the poor fitting.
I managed to replace them and it was working fine for 2 weeks. So last weekend I spent all day fitting new plasterboard, lining paper, dado rail to cover up the value again. and now, yes you guess it, the shower isnt working.
Its a concealed mixer, not too disimilar to this one http://www.plumbworld.co.uk/1674-16358
It had two elbow joints with a kind of filter thing which is loose and sits in the joint. like a 10p piece, black ring with metal gauze.
If I turn it to full hot then nothing at all comes out. Once I start to move to towards to cold then the mixer allows cold through. When we turn the shower on the boiler is not interested, it doesn’t fire up.
All other hot water / heating in the house is fine; bath taps, bathroom sink etc..
Its like something has shut off. There isnt even a dribble so I'm ruling out a build up of gunk?
There is no override value elsewhere that we might have tripped.
Can valve just shut off like that?
I guess I'm going to have to dig into my landing wall again but even if I do that Im not sure what to do once i'm back in there!
any help appreciated
