4 Things to Know About Running Your Pool Pump in Hot Weather

Run the pump 8 to 12 hours a day Most pools need one full water turnover per day. In hot weather, algae grows faster, so 8 hours is usually enough for a properly sized pump, and 12 if your pump is undersized or you have heavy sun exposure.

Do not run it 24/7 Running the pump constantly wastes electricity and wears it out. But do not skimp either—a green pool is far more work than letting the pump run an extra hour.

Check your pool size and pump flow rate Confirm that your pump can turn over the full pool volume in 8 to 12 hours. For most residential setups, that range covers it.

Run it during the hottest part of the day Circulating water when the sun is strongest stops algae from getting a foothold. This saves you from having to shock the pool later.
