Pool Cover Pump Calculator

Estimate how long it will take to clear standing water from your pool cover using a standard utility pump.

Quick Conclusion
Standing water adds massive weight and drowning risk to a pool cover. A standard 350 GPH pump takes approximately 1 hour per inch of water on a standard 16x32 cover. High-capacity 1500 GPH pumps can clear several inches in under an hour.

Technical Comparison

Pump Rating Coverage GPM Flow
350 GPH Standard ~5.8 GPM
1200 GPH High Output ~20.0 GPM
Utility Pump Emergency 30+ GPM

Actionable Steps

Pro-Tip

The "Ice Anchor" Warning: Never attempt to pump slushy or icy water off a cover. The pump can clog instantly, and the weight of the ice is often safer than a partially drained, heavy cover that could collapse. Wait for a full thaw before clearing the cover.
