Rule 500 GPH Standard Bilge Pump Kit w/Float Switch - 12V

The Rule 500 GPH Standard Bilge Pump Kit with Float Switch is a fully submersible 12V bilge pump engineered for reliable water removal across fishing vessels, cruisers, and recreational boats. Rated at 500 gallons per hour (1,893 liters per hour), this pump handles the steady drainage demands of bilge water accumulation without the complexity of manual operation, making it an essential safety component for any boat that spends serious time on the water.

The complete kit arrives equipped with an automatic float switch that triggers the pump only when water level rises, eliminating constant monitoring during overnight docking or extended idle periods. The pump features a stainless steel shaft for corrosion resistance in saltwater environments, paired with high-abrasion, tin-coated silicone-blocked wiring that withstands the vibration and exposure inherent to marine electrical systems. Ignition protection ensures safe operation in gasoline-powered vessel compartments, while the included back-flow preventer stops water from siphoning back into the bilge when the pump cycles off. Mercury-free switch design meets modern environmental standards without sacrificing switching reliability.

Suitable for both weekend anglers and offshore boaters, this 500 GPH pump handles moderate-volume drainage in boats ranging from center consoles to larger cabin cruisers. The completely submersible design permits installation directly in the lowest point of the bilge, reducing plumbing runs and simplifying maintenance. A 3-year manufacturer warranty backs the durability you'd expect from Rule, a marine pump manufacturer with decades of fleet-service history. Compact dimensions and lightweight construction make replacement or upgrade straightforward for boaters managing their own maintenance.
