Wet room drain pumps - manufacturers?

[markocosic]

Hi all,


Wetroom drain pumps to pump from a low level drain UP to the waste drain.

Anybody make them except Whale/Impey's adapted bilge pumps?

Any long term experience with these with regards maintenance? (lifetime of diaphragms and tricuspid valves; resistance to soap and long hair)


A water powered pump would be neat. (rather than sensing mains flow electrically, then controlling drain pump, just power the pump using the incoming mains pressure...)


Thanks,
