My shower pump serves a shower two rooms away with an overhead run of about 8 metres. It has reed switches on hot and cold gravity supplies and starts up every time, but lately it wouldn't stop running when I turned off the shower. I descaled the shower head and this seems to have just about cured it - it runs maybe 1 or 2 seconds then turns off without needing any other action.
Given that the flow gets shut off at the mixer tap and not the shower head, why would descaling help?
Any ideas?
