FAQ
Our expert staff answers customer's most asked questions.
How often should I test my pool water?
Regular testing, ideally once a week, ensures that chemical levels are within the recommended range. This practice ensures that your pool is always ready for enjoyment.
How often should I drain my pool?
It is recommended to drain your pool every three years to eliminate accumulated chemicals and dust. This varies depending on many environmental conditions like fill water and the type of chlorination you are using. Our advice is to have your water tested before and after by a local pool professional.
Can upgrading my pool pump to a Variable Speed (VS) pump save on my electricity bill?
Yes, installing a Variable Speed (VS) pump is a wise decision that promises substantial long-term savings on your electric bill. All VS pumps adhere to Department of Energy (DOE) compliance standards and operate much quieter than single or dual-speed pumps. Experience up to 90% energy savings, and consider our suggested VS pump, the Pentair 013075 IntelliPro3 3 HP VS Pump. Learn more about this product by clicking here.
