Easy hook up exactly like the original pump. Bearings were going out in my pump that was replaced under warranty. Now I have pump I can switch out when the bearings go out. I bought spare bearings because the bearings apparently only last about a year if run year round. This pump is identical to the one that was replaced under warranty.

Install was straightforward, just pay attention to your current spas wiring diagram. Had to get an adapter for the wet end

The product itself is great and works as described, but the packaging could’ve been better. The box was a bit flimsy, and there was some slight damage to the exterior. Fortunately, it didn’t affect the functionality.
