After ordering the part it was shipped out promptly and it was packed very well. Part looks good, not installed yet. l will be ordering from them again for controller boards for the pool equipment. Price could be a little better but overall great company to do business with.

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.
How do I maintain my pool heater?
Regular maintenance is essential for optimal performance. This includes checking the heater's pressure, cleaning filters, and ensuring that the water chemistry is balanced. Consult your heater's manual for specific maintenance guidelines.
Can you add pool automation to an existing pool?
Absolutely, pool automation systems can be easily added to existing pools. You can start with a basic system that controls your filter and pump. Eventually, upgrade to include features like lighting and water features as needed.
