We recently had a Monsoon twin positive head pump .... first of all - it's great (almost)!
However, we have a problem that when we turn off the shower the pump runs on for anything up to 10 seconds. With the shower turned off, if I wiggle the shower thermostat, then it will stop the pump running.
I first thought it might be a faulty flow sensor on the pump, but this doesn't appear to be the case. Whilst the pump is running on (after the shower is turned off), if I close the valves installed close to the pump then the pump will instantly stop.
Any ideas what's going on and how to fix it?
thanks
