Built for the Bilge. Built for the Boat.

Rule started because boaters kept running into the same problem: pumps that quit at the wrong moment, switches that corroded after one season, and utility gear that looked fine on the shelf but fell apart on the water. So we set out to build the kind of marine electrical components that actually hold up — not just to specs, but to real conditions: salt air, vibration, bilge water, and the kind of neglect that comes with a boat sitting all winter.

Every pump, switch, and fitting we make is designed around one question — will this work when you need it to? Not when conditions are ideal, not when the install is perfect, but when you’re taking on water at 11 p.m. and there’s no one to call. That’s the standard we hold ourselves to, and it’s why Rule has been the go-to name in marine pumping for decades.

We don’t make lifestyle gear. We make the stuff that keeps your bilge dry, your wiring clean, and your boat in the water where it belongs. If it’s got our name on it, it’s been built to do its job — quietly, reliably, and without asking for much in return.

Got Questions?

Find straightforward answers to the most common questions about ordering, shipping, returns, and product support.

What shipping options are available?

Standard shipping usually takes 5–7 business days, while expedited options are available at checkout for faster delivery. Orders placed before 2 PM local time on business days are generally processed the same day.

Can an item be returned if it doesn’t fit the intended application?

Yes. Items in original, unused condition can be returned within 30 days of delivery. A return authorization must be requested through the customer support team before sending anything back. Shipping costs for non-defective returns are the responsibility of the buyer.

How do I know which model is right for my setup?

Each product listing includes detailed specs — flow rate, head pressure, voltage requirements, and compatible fittings. Comparing those figures against the specific installation requirements is the most reliable way to select the correct model. The support team can also help clarify if needed.

Are replacement parts available separately?

Yes. Many components — including fittings, floats, and switch assemblies — are available as individual parts. Checking the product page or contacting support with the model number will confirm exactly what’s stocked.

What does the warranty cover, and how is a claim filed?

The warranty covers manufacturing defects in materials and workmanship for the period specified on the product page. It does not cover damage from improper installation, misuse, or normal wear. To file a claim, customers should contact the support team directly with proof of purchase and a description of the issue.

Is it safe to leave a pump running unattended for extended periods

Most models in the line are designed for continuous-duty or automatic operation and are rated for unattended use when installed correctly. Reviewing the installation manual for the specific model is recommended, as operational limits vary. Proper wiring and float switch configuration are critical to safe long-term performance.

The Reviews Are In

Real boats, real conditions — here’s what Rule owners have to say.

Left the boat on the mooring for two weeks during a stretch of heavy rain. Came back to a dry bilge. The auto-sense kicked in exactly when it needed to — didn’t have to touch a thing

Finally replaced the cheap switch that came with my old pump. This one fits cleanly, no mercury, and hasn’t jammed once in two seasons — even with the debris that builds up in my bilge.”

Straightforward installation on a 19-footer. Same wire colors as the old Rule I pulled out, same base footprint — swapped it in under 30 minutes. That kind of consistency matters when you’re working in a tight bilge.
