FAQ
Our expert staff answers customer's most asked questions.
What style of Pop-up head is right for my pool?
This visual guide below will help you identify the appropriate pop-up head for your specific needs.
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 is the function of the Vaclock, and how do I replace it?
Determine whether your Vaclock is threaded or slipped. If threaded, carefully unscrew it. If there are broken pieces, gently chip them out without damaging the threads. For a Slip Vaclock replacement, cover the top with a towel or rag and use a rubber mallet to tap in the new one.
