Shower Pump start as a result of other taps
Having moved into a new house, I have a strange problem. Sometime on
using a tap (either upstairs or downstairs), the pump starts working. As this is a mira PPT3 which is connected to a mira mixer shower 88, this should only start as a result of turning the shower on. The way to stop the pump to to go to the upstairs bath and run the hot water for a minute until and then slowly turn the tap off the noise stops. Its as if the pump is starting in reverse !! Having looked at the news group my first Idea was a one way valve but could this cause my problems also have come across a surrey(sussex) value on the news group should this solve my problem. Any ideas welcome !! Gary gary.hol t@ talk21 . com |

Any ideas welcome !! Gary gary.hol t@ talk21 . com We had a similar problem with our twin impeller Showerforce pump. Using some of the hot taps would cause the pump to momentarily start and I was concerned that it would shorten the life of the pump. I completely disconnected the hot water flow switch on the pump. The pump now takes a little longer to start (on the cold water flow switch) but this is acceptable. It no longer 'blips' every time a hot tap is used. Best check with Mira that this mod wouldn't cause any harm to the pump, and only do it yourself if you are electrically competent. hth Allan |

The pump keeps on going and will only stop via either the bath or basic
(bathroom upstairs) staps being run for a few mins until the noise stops. I suspect the water contains air !!!! |
