Pool cover pumps are measured by the number of gallons of water they pump per hour, which is expressed as GPH. The higher the GPH, the faster the pump removes water and the better it works. Most pumps are capable of pumping out hundreds of gallons per hour. Pumps also come in different varieties, such as some that attach to a garden hose that pump the water out, whereas others work even when submerged in water.

It’s advised to bring your cover pump, including hoses, inside during freezing weather. After the chilly winter weather has passed, you can remove all the water while it’s unfrozen and in liquid form. As the snow melts, if the temperature drops again, it will freeze once more, so you’ll want to get the water off your cover while you can. Most cover pumps are not freeze protected.

Cover pumps are submersible, which will protect your pool cover from accumulating excess water. Automatic pumps will turn on automatically when they detect water and shut off when the water has been removed. For manual pumps, operation requires manual turning on and off.

Automatic pumps are typically more expensive but also more efficient than manual pumps. These pumps can be placed on top of your cover and will detect when water has accumulated and needs to be removed. The pump will then turn itself on to remove the water. The pump also knows when there is no longer any water to collect and will turn off.

Manual pumps require a more hands-on approach and monitoring. As water accumulates, you must pay careful attention to your pump to know when to turn it on and off when the water has been drained.

When choosing a cover pump, consider its flow rate, power source (including cord length), and automation (automatic vs. manual). Other important features may consist of its durability, noise level, ease of use, and whether it’s submersible or not.
