the other day I noticed I had a weeping CH pump isolating valve, it was dripping from the wide pump port. So I dropped a cup under it, and today set about fixing it.
Wind down the isolators, and get my large water pump pliers on the leaky side and with the first twist...
b*****
Water now peeing out of both sides of pump
Isolator not isolating
Emergency drain down required
Will the valves come off the pump? will they my willy. So off with the pump and isolators in one fell swoop (been here before - I designed a bit of "play" in the pipe work so they can sprung out)
So for the last 4 hours I have been trying to get isolators off the pump, one came off eventually but the other simply refuses to budge. Its been wacked, heated, oiled, nearly wrecked the workmate in the process, but it wont budge short of being cut off.
So I am now off to screwfix for a new pump, isolators, and fernox inhibiter. Currently we have no hot water and no ch.
