Johnson Pump Multi-Port Shower Sump Pump (57151)

Johnson Pump Multi-Port Shower Sump Pump (57151)

The Johnson Pump Multi-Port Shower Sump is a compact, fully submersible sump pump designed for marine shower, sink, and condensation drain applications. Multiple inlet ports allow it to handle several drain sources simultaneously shower, sink, and condensation from a single pump unit. An Ultima automatic float switch activates the pump when water reaches the trigger level and shuts it off when the sump is clear, with no manual intervention required.

A built-in inlet screen traps hair and debris before they reach the pump, and the clear see-through lid allows quick visual inspection without disassembly. A built-in check valve prevents backflow. Saltwater-tough construction and Made in USA.

• Marine shower sump installations

Parts Desk Insights

The multi-port sump is the most practical solution when a boats shower compartment also collects sink drainage or condensation rather than running separate pumps for each source, one unit handles all of them. The automatic float switch means it runs only when needed and stops on its own, which is important in an unattended bilge or sump. The clear lid and removable inlet screen make routine maintenance straightforward without pulling the pump. For higher-volume grey water or bilge applications where a diaphragm pump is preferred over a sump design, see the Viking Power 16 or Viking Power 32.
