The Rule 800 GPH Legacy Shower Drain Replacement Pump is a direct 12V replacement built specifically for legacy 97A and 98A shower drain boxes, not for general bilge duty.
For standard bilge requirements, Rule points to its 20DA part number instead, so it’s worth confirming the application before ordering rather than assuming this pump works as a general-purpose bilge replacement.
It connects to 19mm (3/4-inch) bore hose, stands 95mm high on a 60mm base, and moves up to 50 liters per minute (11 gallons per minute) against a maximum recommended discharge head of 2 meters, protected by a 5-amp fuse. Browse more shower sump systems.
