Popped in to the in-laws today to collect the pup, to find water
dripping through a ceiling.
Traced it to an isolation valve in a bathroom, but waht I didn;t
understand was it wasn't the valve to pipe joint that was weeping, but
the actual operating arm - the bit with the slot for the screwdriver -
that was weeping.
Obviously its get the plumbers in and get it replaced - I am not going
to spend hours finding out how to drain someone elses bloody CH system -
but the question is, how are these bits normally sealed? I thought the
balls were an interference fit in the housings, and water couldn't come
out of the pivot.
But the whole ball assembly seemed loose.
As an aside, me and pa-in-law wound some PTFE tape round it, every which
way, and wrapped it in PVC electrical tape, and that's stopped the drips
till the plumber arrives, so there's another bodge to add to yer
