<h3>Rule Industries: The Gold Standard in Marine Water Management</h3><p><strong>Rule Industries</strong> has been synonymous with marine pump reliability since 1965. Founded when inventor Clinton Rule set out to solve the all-too-common problem of a leaky boat, the brand grew from a single innovative product into the world's most recognized name in submersible bilge pumps. Today, Rule operates under the Xylem family of water technology brands, but its identity — and its commitment to keeping vessels dry and boaters safe — remains as focused as ever.</p><p>For over five decades, Rule has set the industry benchmark in marine water management. Whether you're a weekend recreational boater, a tournament angler, or a commercial vessel operator, Rule's engineering philosophy is straightforward: build equipment that performs when it matters most. That reputation has earned Rule a place on the spec sheets of boat builders around the globe, with professionals and DIYers alike reaching for the Rule name when reliability is non-negotiable.</p><h3>Electric Bilge Pumps: Rule's Flagship Product</h3><p>The heart of the Rule lineup is its range of <a href="/6623-rule-industries-electric-bilge-pumps-200350">electric bilge pumps</a>. Available in both manual and automatic configurations, Rule bilge pumps are engineered to remove water from the lowest point of a boat's bilge efficiently and reliably. Automatic models feature water-sensing switches that activate the pump as needed, offering hands-free protection without draining the battery. Heavy-duty models incorporate stainless steel shafts, marine-grade blocked wiring, and ignition protection, while the Gold Series pumps are backed by a five-year guarantee — a testament to Rule's confidence in its own craftsmanship.</p><h3>Livewell &amp; Aerator Pumps for Serious Anglers</h3><p>Rule's expertise in water movement extends naturally into the fishing world. The brand's <a href="/6623-rule-industries-livewell-aerator-pumps-200624">livewell and aerator pumps</a> are engineered to circulate and oxygenate water in livewells and baitwells, keeping catch and live bait healthy throughout a long day on the water. Rule's Oxygenator Systems infuse air at the pump impeller to produce micro-fine bubbles that remain suspended longer, maximizing oxygen transfer to your bait or catch. The Tournament Series models feature a cartridge-style motor design that can be removed and replaced quickly — even mid-trip — keeping downtime to a minimum.</p><h3>Blowers, Plumbing &amp; Accessories</h3><p>Rule rounds out its marine offering with a suite of supporting products that complement its pump lineup. The brand's <a href="/6623-rule-industries-blowers-200176">bilge blowers</a> provide ventilation for engine compartments, bilges, galleys, and heads, featuring corrosion-resistant motor housings, front and rear shaft seals, and USCG 183.410 ignition-protection compliance. For system builders and installers, Rule also offers <a href="/6623-rule-industries-plumbing-parts-accessories-200786">plumbing parts and accessories</a> along with <a href="/6623-rule-industries-nylon-pipe-hose-fittings-200724">nylon pipe and hose fittings</a> — the connective tissue that ties a complete marine plumbing system together. With a catalog spanning over 135 products, Rule gives boaters everything they need to build, maintain, and upgrade their vessel's water management systems from a single trusted source.</p><h3>Why Boaters Trust Rule</h3><ul style="list-style:disc"><li>Over 60 years of continuous marine pump manufacturing since 1965</li><li>Submersible bilge pump designs trusted by boat builders from the factory</li><li>Automatic and manual models to suit every vessel type and size</li><li>Products engineered to meet rigorous commercial and recreational standards</li><li>Part of the Xylem global water technology portfolio</li><li>Wide availability through marine dealers across the US, Canada, Australia, UK, and beyond</li></ul>

Product Details

The Rule Industries RM800B Rule-Mate is an eco-friendly automatic bilge pump that eliminates the need for a separate float switch through innovative solid-state water sensing technology. This 800 GPH, 12-volt pump uses unique "field effect" technology that intelligently detects water while ignoring petroleum-based fluids, preventing false activation from straight motor oil in the bilge.

Key Features:

  • 800 gallons per hour pumping capacity for reliable bilge water removal
  • Solid-state water sensing eliminates mechanical float switch failures
  • Field effect technology prevents false activation from oil contamination
  • Automatic operation for hands-free bilge management
  • 12-volt DC operation for standard marine electrical systems
  • Compact design fits easily in tight bilge spaces
  • Easy installation with included mounting hardware

The Rule-Mate automatic bilge pump provides peace of mind with its intelligent sensing technology and dependable performance. The solid-state sensor is more reliable than traditional float switches, with no moving parts to jam or corrode. Ideal for powerboats, sailboats, and personal watercraft requiring automatic bilge pumping up to 800 GPH.
