Frequently Asked Questions

How long should I run my pool pump in summer?

Summer generally needs longer daily run times than winter, since warmer water encourages algae and bacteria growth faster — many pool professionals suggest running long enough to turn over the full pool volume at least once a day, more in peak heat.

How do I prime a pool pump for the first time?

Fill the pump strainer basket with water, ensure the lid is sealed, open any air-relief valve, and switch the pump on — it should draw water within a minute or two. If it doesn’t prime, check for suction-side air leaks first.

Can I circulate pool water without a pump?

Not effectively for filtration or chemical distribution — a pump is what drives water through the filter and around the pool. Without one, water quickly stagnates and chemicals stop distributing evenly.

How long should a pool pump motor last?

Many pump motors last around 8-15 years with reasonable care, though this varies with usage hours, water chemistry, and build quality — unusual noise or reduced flow are early warning signs worth investigating.
