Let’s Talk About Rule 3700 Automatic Bilge Pump
The Rule 3700 Automatic Bilge Pump isn’t just another piece of equipment; it’s a critical component for any boat owner serious about safety and reliability. Manufactured by Rule, a name synonymous with marine pumping solutions, this pump boasts a heavy-duty construction designed for both commercial and pleasure boat use. This automatic 12v pump promises a trouble-free operation and the capacity to move a significant amount of water.
My journey to the Rule 3700 Automatic Bilge Pump began with a near-disaster on my old fishing boat. A leaky through-hull fitting, coupled with a failing, undersized bilge pump, had me frantically bailing water by hand during a sudden squall. I needed a reliable, high-capacity solution to prevent a repeat performance.
Upon unboxing the Rule 3700 Automatic Bilge Pump, I was immediately struck by its robust build. The black, heavy-duty plastic casing felt solid and well-constructed. Its weight hinted at the powerful motor inside, and the 1-1/2″ discharge outlet inspired confidence.
Compared to the old 1000 GPH pump I was replacing, the Rule 3700 Automatic Bilge Pump felt like a serious upgrade. I considered a competitor’s model with a similar GPH rating, but Rule’s reputation for longevity and the integrated automatic float switch sealed the deal. The others lacked the proven track record.
My first impression was a mix of relief and anticipation. Relief that I finally had a pump I could trust and anticipation to see how it performed under pressure. This pump needed to deliver, and I was ready to put it to the test.
Real-World Testing: Putting Rule 3700 Automatic Bilge Pump to the Test
First Use Experience
I tested the Rule 3700 Automatic Bilge Pump on my 24-foot center console fishing boat in the often-unforgiving waters of the Gulf of Mexico. Installation was straightforward, thanks to clear instructions and standard fittings. The true test came during a week-long fishing trip notorious for unpredictable weather.
The pump encountered everything from moderate chop to driving rain and even a rogue wave that sent a surprising amount of water over the bow. The Rule 3700 Automatic Bilge Pump handled it all with ease, kicking on automatically and quickly evacuating the water. I noticed the speed with which it emptied the bilge after a particularly heavy downpour.
The automatic function was seamless; I didn’t have to think about it. After a couple of minor adjustments to the float switch position, it worked perfectly. It was reassuring.
There were no issues or surprises during the initial use. The pump operated quietly and efficiently, giving me peace of mind to focus on fishing. My only concern was the relatively high amp draw.
Extended Use & Reliability
After six months of regular use, the Rule 3700 Automatic Bilge Pump continues to perform flawlessly. Even after repeated exposure to saltwater, bilge grime, and the occasional fish scale, it shows no signs of slowing down. It has seen countless hours of use.
Durability has been impressive; the pump casing remains intact, and the float switch operates smoothly. There is no corrosion or cracking. Even the wiring connections are still secure.
Maintenance is simple: a quick rinse with fresh water after each trip keeps it clean. Periodically checking the intake for debris is also crucial, but that’s standard for any bilge pump. I also spray a corrosion protectant on the electrical connections every couple of months.
Compared to my previous pumps, which typically failed after a year or two, the Rule 3700 Automatic Bilge Pump is in a different league. Its reliability and performance have exceeded my expectations, making it a worthwhile investment. It has been a noticeable and substantial improvement over previous pumps.
