5 Reasons Not to Run Your Pool Pump 24/7 During a Heatwave

It’s unnecessary for water turnover Most pools only need 8–12 hours of pump runtime to turn over the full volume once or twice a day. During a heatwave, 12–14 hours is plenty.

It wastes electricity Running the pump nonstop drives up your electric bill for no real benefit. Bumping runtime to 12–14 hours is enough.

It wears out the pump faster Continuous operation accelerates wear on the pump motor and components, shortening its lifespan.

It can add heat to the water Running the pump during the hot daytime can actually warm the water. Run it during cooler night or early morning hours instead.

Maintenance matters more than extra runtime Checking the skimmer and cleaning the filter does more to prevent stagnation than running the pump an extra eight hours.
