Description
Automatic cover pump designed to remove standing water from pool covers, boat covers, and rooftops. The submersible pump activates automatically to start pumping when water reaches the intake and stops when water drops, protecting covers from excess weight and damage. It connects to a standard garden hose and is portable for seasonal or occasional use.

How It Works
A pool pump is the heart of the circulation system. The motor spins an impeller that pulls water from the skimmers and main drains, pushes it through the strainer basket and filter, then sends it through the heater, sanitizer and back to the pool through the returns. Flow (gallons per minute) and head (resistance from pipe, fittings, filter and heater) decide how much water actually moves. Variable speed and multi-speed models let you run lower speeds for everyday filtration, which cuts energy use dramatically because power draw falls far faster than flow.
How to Choose the Right Utility Pump
- Match horsepower and total horsepower (THP) to the plumbing and equipment, not just the old pump label. Oversizing wastes energy and can exceed filter and heater flow limits.
- Confirm voltage (115 V, 230 V or dual), phase and the available breaker. Commercial pumps are often three-phase.
- Check port size, union type and the plumbing height so the new pump lines up with existing pipe.
- Most replacement residential filtration pumps sold in the U.S. must meet DOE dedicated-purpose pool pump efficiency rules, which is why variable speed models dominate.
- For spas and water features, match the flow the jets or feature require.
If you are replacing an existing part, the fastest way to confirm compatibility is to match the brand and model number on the old equipment. Send us the model number or a photo of the label and our team will help confirm the 577301 is the right fit before you order.
Installation and Safety
Pumps should be installed on a level, solid pad, plumbed with the correct size pipe, wired to a properly sized dedicated circuit with GFCI protection where required, and bonded per NEC Article 680. Line-voltage wiring and bonding should be done by a licensed electrician or qualified pool professional. Never run a pump dry; prime the strainer housing before starting.
Maintenance Tips
- Empty the strainer basket weekly and inspect the lid O-ring; lubricate it with silicone-based lubricant.
- Listen for bearing noise, a sign the motor bearings are wearing.
- Check for leaks at the shaft seal; a dripping seal should be replaced quickly before water reaches the motor bearings.
- Keep the motor vents clear of debris, mulch and sprinkler spray.
- Winterize in freezing climates by draining the pump body.

Frequently Asked Questions About the Little Giant 577301
What size pump do I need?
Size to your pool volume, desired turnover, plumbing size and equipment flow limits. Bigger is not better; a correctly sized variable speed pump running slowly usually filters better and costs far less to run.
Can I replace a single speed pump with a variable speed pump?
In most cases yes. Confirm plumbing alignment, voltage and controls. Many variable speed pumps include onboard timers or connect to automation systems.
Why is my pump losing prime?
The usual causes are an air leak on the suction side (lid O-ring, drain plugs, valve stems or unions), a low water level or a clogged basket.
Is this the genuine Little Giant part?
Yes. It is brand new Little Giant equipment (model 577301) covered by the manufacturer warranty. Warranty terms vary by product and application; see the manufacturer documentation or ask our team.
