Had a shower pump for the last fifteen years which I replaced a year or so ago because it had given up the ghost but the pipework's the same as it's always been.
Recently when turning off any hot tap anywhere in the house the shower pump will cycle on for ooh as a guess less than half a second. Sort of about the same time as you can say brrrrr. Then it'll go off again. If we turn any hot tap off slowly it doesn't do it but if we turn the tap off as usual then brrrr off it goes.
Plumbing to the shower comes from an essex flange (??) on the top of the tank to feed to the 3bar shower pump. All piping's in 22 mm reducing to 15mm at the thermostatic valves.
So, anyone got any ideas as to what it can be or what I should do?
TIA and a Happy New Year to you all.
