Hi please can you tell me I have a shower pump, grundfos 96787422 / STC-1.5 C which continually runs.... Is this the flow switch fault?
If so please can I have the details, thank you!
Hello, either one of the floats (in the vertical outlet volute pipe) is stuck in the up postition or the electrical switch is stuck in the on postiton
the flat can be cleaned and made free, the electrical part can be tested for open/closed circuit
there are two types of switch BP438 clip on and BP446 held on with a cable tie.
We hope this info helps.
we have a watermill shower pump type PR50D that has started to pulsate when turned on. Have checked the shower hose, the water feeds and outlets and all seems OK. But it seems like there is no flow through the cold side when powered up. Your suggestions would be welcomed.
Hello, we think this may be a failed impeller or air in the system.
