  • Sp-330d

    I just recently put in this pump (I replaced the same model), it pumps out half the water then shuts off, the old one pumped out all the water. It seems to be working fine, but my issue is it normal for 2 same models to operate so differently? Is there any adjustment on the switch? I am using it for a sump pump.

    Any help is appreciated.

    the pumps work on a diaphram switch which basicly the deeper the water is the more presure is on the diaphram the big problem I have with those types are the older they get the higher the level of the water gets mostly because of debree build up on the diaphram so no the new one is probably working fine and the old one the switch was going bad and here is the link for the pump for all
