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.
Do robotic pool cleaners operate effectively in salt water ?
Robotic pool cleaners work effectively in saltwater pools. The SharkVAC is one model that is designed with corrosion-resistant materials and advanced filtration systems that handle saltwater environments without damage.
To insure the life span of the product remove the robotic cleaner from the pool after each cycle.
Do you need an electrician to change a pool light?
Working with an electrician is advisable for pool light replacements, especially if there's a need to repair or update existing wiring or install new wiring for additional lights.
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.
