Standing water on a pool cover is one of the fastest ways to damage it. The weight causes structural stress, the stagnant water breeds algae and mosquitoes, and in freezing temperatures it can pull the cover into the pool or freeze it into an unusable solid sheet. A cover pump solves all of this — but you need the right one for your situation.
Manual pumps require you to plug them in when water appears and unplug when the cover is dry. They're less expensive ($30–$70) and slightly more powerful than automatic units, but they depend entirely on someone remembering to run them. For residential clients who check their pool frequently, manual pumps work fine.
Automatic pumps have a float switch that activates when water depth reaches a threshold (usually 1/4–1/2 inch) and shuts off when the water is gone. They protect the cover continuously without intervention. For clients who travel, for commercial pools, or for spring pool opening season, automatic pumps justify the $70–$150 price premium.
| Pump | Type | Flow Rate | Price | Best For |
|---|---|---|---|---|
| Wayne WAPC250 1/4HP | Automatic | 2,750 GPH | ~$95 | Most residential covers |
| Little Giant APCP-1700 | Automatic | 1,700 GPH | ~$75 | Budget automatic option |
| Danner 02430 | Manual | 1,500 GPH | ~$35 | Cost-conscious homeowners |
| Coverstar A1700A | Automatic | 1,700 GPH | ~$110 | Solid construction, reliable |
| Superior Pump 91250 | Manual | 1,800 GPH | ~$45 | Value manual pick |
Wayne's 1/4 HP automatic cover pump is the most recommended unit for residential pool covers across the industry. The float switch activates at 1/2 inch of water and shuts off cleanly at dry. At 2,750 GPH, it clears water faster than most alternatives, meaning it runs for shorter cycles and experiences less wear. The 25-foot power cord and 25-foot discharge hose reach most discharge points without extension. At $95, it's the right investment for any inground pool with a winter cover.
At $75, the Little Giant APCP-1700 offers automatic operation at a lower price than Wayne. The 1,700 GPH flow rate is adequate for most residential covers. The float switch is reliable, and the unit has good dry-run protection. One downside: the included hose is shorter (18 feet), which may require purchasing an extension for covers that discharge away from the pool.
When servicing pools during winter close months, check cover pump operation as part of every visit. Confirm the float switch activates by adding a small amount of water near the pump and watching it engage. A pump that has failed during winter can allow cover collapse, which can be expensive damage to discover at spring opening.
Center the pump on the lowest point of the cover where water naturally pools. Most covers sag slightly in the middle — this is the right spot. Ensure the discharge hose drains downhill and doesn't create a loop that could create back-pressure. Run the hose to a lawn area, garden bed, or storm drain at least 10 feet from the pool to prevent the pumped water from seeping back under the cover or into pool groundwater.
Never allow a cover pump to discharge where the water can freeze and block the hose. A frozen discharge hose causes the pump to run against closed head, which overheats the motor. Check discharge paths after every freezing event during winter.
At end of season or when the cover is removed for pool opening, drain the pump completely, dry it, and store it indoors. Water left in the pump housing during freezing temperatures cracks the housing and destroys the impeller. Most pump failures are storage failures, not use failures. A pump stored properly should last 3–5 seasons.

A standard sump pump can work in an emergency but it may be too powerful for thin cover materials and the hard base may damage a soft cover. Dedicated cover pumps are designed with softer bases and appropriate flow rates for cover use.
Quality automatic pumps have automatic dry-run protection that shuts the motor off when no water is detected. Always confirm your pump has this feature before leaving it unattended for extended periods.
Most cover pump discharge hoses are routed to a nearby lawn, garden bed, or storm drain. Avoid discharging into a sanitary sewer without checking local regulations. The water from a pool cover contains contaminants and is not suitable for drinkable water sources.
Use a cover pump with a filter screen or strainer basket. Alternatively, place the pump in a mesh bag or use a leaf net over the pump intake. Clear the screen or basket whenever you check the pump during heavy debris season.
