FAQ
Our expert staff answers customer's most asked questions.
Can you change a LED pool light without draining water?
No, typically you don't need to drain the pool to replace an underwater light. Most LED fixtures allow for bulb replacement while submerged, but ensure the power is off before proceeding.
Are there any specific considerations for saltwater pools?
Yes, saltwater pools require pumps that are compatible with saltwater systems. Look for pumps made from corrosion-resistant materials to ensure longevity and efficiency in saltwater environments.
Is it OK to replace a 1 HP pool pump with a 1.5 HP?
Yes, you can replace a 1 HP pump with a 1.5 HP pump, provided the exterior dimensions are the same. However, be cautious about the impeller; while it will fit, it won't pump more water since both motors turn at the same RPM.
