FAQ
Our expert staff answers customer's most asked questions.
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.
What are the ideal chemical ranges for my pool?
Achieving a balanced pool involves maintaining a pH range of 7.2–7.8, total alkalinity between 80–120 ppm, calcium hardness at 180–220 ppm, and cyanuric acid (stabilizer) within 30–50 ppm. Chlorine levels should consistently fall within the 1–3 ppm range, by may need to be increased as CYA levels go above 60 PPM.
How frequently should I clean my filter cartridges?
The cleaning frequency is contingent on your filter's size. As a general guideline, initiate the cleaning process when the filter pressure exceeds the initial pressure by 10 psi. This ensures optimal filtration efficiency.
