Let’s Talk About Rule 3700 G.P.H. “Gold Series” Bilge Pump
The Rule 3700 G.P.H. “Gold Series” Bilge Pump is a heavy-duty submersible pump designed for both commercial and recreational boats. Manufactured by Rule, this pump boasts a high capacity of 3700 gallons per hour, making it a powerful solution for removing water from your vessel. Known for its reliability, the Rule 3700 is a popular choice among boat builders and owners alike.
My own need for a reliable bilge pump arose from a near-disaster a few years back. A sudden squall caught us out on Lake Michigan, and the aging pump in my 28-foot cabin cruiser simply couldn’t keep up with the incoming water. I swore then that I would never again compromise on bilge pump performance.
The Rule 3700 arrived in a sturdy cardboard box, well-protected by molded foam. The initial impression was of a robust, well-constructed piece of equipment. Its black finish and compact design suggested durability and efficiency, while the weight felt substantial but not overly heavy.
Compared to the Attwood Sahara S1200 and the Johnson Pump 2200 GPH, the Rule 3700 stood out for its higher pumping capacity and reputation for long-term reliability. While the others are decent, the Rule felt like a significant step up in terms of overall quality and performance. I chose it specifically for its ability to handle larger volumes of water quickly, providing an extra margin of safety.
My first impression was one of cautious optimism. The pump looked the part, but the real test would be how it performed under pressure.
Real-World Testing: Putting Rule 3700 G.P.H. “Gold Series” Bilge Pump to the Test
First Use Experience
I tested the Rule 3700 in several scenarios, including simulated flooding in my boat’s bilge, and during a particularly rainy weekend on the Puget Sound. It was also used to pump out water from a flooded dinghy after some rather adventurous wave jumping. The pump was fully submerged during each test.
The pump performed flawlessly in all conditions, including handling some debris-laden water without clogging. Its high pumping capacity quickly evacuated the water, giving me confidence in its ability to handle real-world emergencies. Installation was straightforward and the pump operated quietly with minimal vibration.
There were no issues, however, the pump did seem to cycle on and off quite a bit during some tests. I soon realized this was due to the placement of the float switch being too high, it was easily remedied.
Extended Use & Reliability
After six months of regular use, the Rule 3700 continues to perform admirably. There are no signs of wear or tear on the housing or impeller, even after frequent use in saltwater environments. Regular rinsing with fresh water after use has kept it in excellent condition.
Cleaning the snap-lock strainer is quick and easy, which is essential for preventing clogs and maintaining optimal performance. Compared to my previous bilge pump, the Rule 3700 is noticeably more robust and reliable, providing peace of mind during extended trips.
It has been incredibly easy to maintain. A quick spray of fresh water and occasional check is all it needs.
