When we bought our Santorin the surveyor found the pump not to be working properly. In our early ignorance we had the pump removed and replaced with a Jabsco. Since joining the forum we have taken the advice never to change anything Henri installed! The pump (Jabsco) didn't last very long. An earlier post on this topic suggested the Whale Gulper 320. This works well. I have two as it takes less than two minutes to swap should I need to.
I have a Jabsco sump pump and have found it unreliable . The motor works fine , I have replaced everything and it still fails to pump water from the bilge every time. I have replaced the joker and flap valves and I have a check valve , but I think over time the pump slowly loses its prime and becomes air bound , when not used for some time. I have thought about buying a new one and hope it works better . I have looked everywhere and cannot find it . I assume all SMs have the same pump , can someone tell me where I can purchase a new one. Has anyone replaced it with something more reliable ?
