    Replacement Potable Water pump-gctid397100

    My potable water pump has had a very small leak when pumping and lately

    It has gotten much worse. It is spraying water from the bottom of the pump when the switch is on. Its probably time to replace it.

    My question is: What would be a suitable replacement for the existing pump? My main concern is finding pump that will have the same size fittings and connections. Those of you that have replaced the pump, what did you replace it with?

    I assume you cannot get the part number/manufacturer off the existing pump?

    I recently replaced my water pump, and I had thought there might be trouble getting one with the same fittings - but I believe they are all standard - 15 mm tubing for your water lines, should all use the same connectors to attach to the pump.

    I replaced my FloJet with the exact same model that was already in the boat, but when I was looking around, they all seemed to have the same openings.

    Aside from the fittings, I think the only consideration that differs from pump to pump is your flow rate and psi. my boat, slightly smaller than yours uses the 4405-143 which delivers 3.3 gpm and shuts off at 35 psi.


      It's no good the way it is. Jerk it out of there and get a new one. Most brands are compatible.

        Pull the pump out and get the same brand, that will pretty much guarantee you can re-use the fittings. They are NOT all the same. Shurflo, Jabsco, Flojet, Aquajet (Johnson) are the major players. 3-4 gpm at 35-40 psi is the standard range. Easily available at West Marine, Camping World, some Walmarts, or any RV supply.
