Johnson Pump 57151 Shower Sump Multiport Pump, 1000 GPH, 12V, Grey

The Johnson Pump 57151 is a compact 12V shower sump pump built for boats that need to clear waste water from more than one fixture at once. Its multiport design accepts a discharge hose plus multiple intake hoses, so a single pump can handle drainage from a shower pan, galley sink, or dish-washing machine tapping into the same sump. The tight-fitting lid on the housing helps minimize odors and splashing inside the boat, which matters in a below-deck installation where the sump sits close to living space. Inside, the pump uses a stainless steel shaft and a lip-type shaft seal, paired with a thermoplastic pump body for corrosion resistance in a wet bilge or shower sump environment. A check valve is built into the outlet side, stopping water that has already been pumped out from flowing back into the sump when the pump cycles off. The unit runs on 12 volts DC and is sized for a 3/4 inch discharge hose, with intake hose fittings that accept 3/4 inch, 1-1/8 inch, and 1-1/2 inch hose depending on which inlet ports are used. This is a direct fit as a replacement or upgrade for an existing Johnson Pump 57151 shower sump multiport pump, and it is finished in grey to match the original housing color.
