3 Things to Know About Pump Size for a Flat Pool Cover

A 1/4 HP pump is usually enough Flat pool covers don’t hold much standing water, so a 1/4 horsepower pump clears them in a reasonable time without being overkill.

A 1/3 HP pump works if you need more speed It handles longer hose runs or slightly faster drainage, but 1/6 HP is too slow for anything but the smallest wading pools.

Avoid extremes in pump size A tiny pump takes all day, and a 1 HP pump is overkill for a cover that barely holds an inch of water. Match the pump to your hose length and how often you use it.
