<h3>Rule Industries: Five Decades of Marine Pumping Excellence</h3> <p>Since 1965, Rule Industries has been a trusted name in marine solutions, setting the industry standard with high-performance submersible bilge pumps. As part of Xylem's portfolio of water technology brands, Rule has built an exceptional reputation among commercial fishermen, recreational boaters, and marine professionals who demand equipment that performs when it matters most. As marine technology developed, Rule stayed ahead, delivering pump systems that became the go-to choice for commercial fishermen and recreational boaters alike.</p> <p>Every boat owner faces the same challenge: water intrusion is inevitable. Whether from rain, splash-over, or slow leaks, managing bilge water is critical to vessel safety and longevity. That's where Rule's engineering expertise becomes essential. Rule pumps have built their reputation in the field—through storms, mechanical failures, and those high-pressure situations where reliable water removal is the difference between a close call and a catastrophe.</p> <h3>Comprehensive Marine Water Management Solutions</h3> <p>Rule's product lineup centers on one core mission: keeping vessels dry and operational in any condition. Their <a href="/6623-rule-industries-electric-bilge-pumps-200350">electric bilge pumps</a> form the foundation of this commitment, offering flow rates from 360 GPH to over 3800 GPH to match any vessel size and water accumulation challenge. These pumps feature marine-grade construction designed to withstand salt spray, temperature extremes, and constant moisture exposure that would quickly destroy lesser equipment.</p> <p>Understanding that automation is key to peace of mind on the water, Rule offers multiple control solutions. Their <a href="/6623-rule-industries-float-switches-200426">float switches</a> provide reliable automatic activation when water levels rise, eliminating the need for constant monitoring. For comprehensive vessel protection, Rule's <a href="/6623-rule-industries-bilge-pump-switches-alarms-200163">bilge pump switches and alarms</a> deliver layered safety systems that alert operators to water intrusion while automatically managing removal. Rule Automatic Bilge Pumps feature built-in sensors that check for water every 2.5 minutes, ensuring continuous protection without manual intervention.</p> <p>Beyond bilge management, Rule provides specialized solutions for other marine applications. Their <a href="/6623-rule-industries-air-pumps-adaptors-200078">air pumps and adaptors</a> support livewell systems critical for fishing operations, while their extensive range of <a href="/6623-rule-industries-plumbing-parts-accessories-200786">plumbing parts and accessories</a> ensures that complete fluid management systems can be built, maintained, and upgraded using Rule components.</p> <h3>Engineering That Stands Up to Marine Environments</h3> <p>Rule's commitment to quality and durability makes their pumps the first choice among do-it-yourselfers and professional installers alike. The brand's pumps undergo rigorous testing to ensure they deliver rated flow rates even under challenging conditions. Their cartridge-style pump designs allow for easy maintenance—when debris clogs the strainer or impeller, the motor cartridge can be quickly removed for cleaning and reinstalled, minimizing downtime.</p> <p>High-quality materials handle salt spray, temperature swings, and constant moisture without breaking down, designed to keep working in conditions that destroy lesser equipment. This durability translates to real-world reliability for boaters who need equipment they can count on when far from shore, facing rough seas, or leaving their vessels unattended.</p> <h3>Why Marine Professionals Choose Rule</h3> <p>Rule's position in the marine industry reflects decades of proven performance. The brand's pumps are specified by boat manufacturers, recommended by marine technicians, and chosen by vessel owners who understand that bilge pump failure isn't just an inconvenience—it's a serious safety risk. From small recreational craft to larger commercial vessels, Rule provides scalable solutions backed by widespread availability through marine dealers and distributors worldwide.</p> <p>Whether you're replacing a worn pump, upgrading to automatic operation, or building a new vessel, Rule Industries delivers the marine pumping technology that keeps boats dry, protected, and ready for whatever conditions they encounter on the water.</p>

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
