<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 33ALA High Water Bilge Alarm is a complete 12-volt DC monitoring system designed to alert boaters to rising bilge water levels before they become a serious problem. The kit includes a mercury-free Rule-A-Matic Plus float switch and a compact in-dash gauge that delivers both a visual LED indicator and a loud 85 dB audible alarm, ensuring you receive a clear warning even in noisy onboard environments.

Designed for continuous, unattended monitoring, this system is ideal for larger yachts, commercial vessels, and any boat with compartments that aren't under constant observation. The float switch activates the alarm when water levels rise, providing an early warning that allows time to respond before damage occurs. For vessels with multiple compartments, additional Rule float switches can be added to the system to expand coverage.

Key Features:

  • Complete kit includes mercury-free Rule-A-Matic Plus float switch and in-dash gauge
  • 85 dB audible alarm plus bright LED visual alarm indicator
  • Designed for 12-volt DC electrical systems
  • Maximum current draw: 20 amps — use 14 AWG wire
  • Dash gauge requires a 2.125" hole cutout for flush mounting
  • Gauge diameter: 60mm (approximately 2.36")
  • Ignition protected for safe use in enclosed engine compartments
  • Expandable — add additional Rule float switches for multi-compartment monitoring
  • Complies with CFR 182.530, which requires visual and audible alarms in each unmanned space on commercial vessels 26 ft. or more in length
  • 2-year manufacturer warranty

The Rule 33ALA High Water Bilge Alarm is a reliable, regulation-compliant solution for keeping bilge water in check and protecting your vessel from undetected flooding.

Fast shipping time good price

Great prices and great selection

I'm waiting on my refund. I was not happy that I couldn't talk to a real person regarding my return and my repurchase of the correct prop that I needed. So , if I get my total refund without a huge restocking fee(since the prop is new in original packaging and I bought another prop that is the correct size) then I will be extremely satisfied.

Quick delivery and great customer service

I paid a little extra for the fast delivery but it was worth it. I got it quickly and it worked great

All good

Ordering is very easy. Prices are good. Very helpful staff.

Thanks
