Pump went in and on with no problems. The pump does not come with the 3/8 barbed fitting for the pressure release like the original one does so make sure you buy one when ordering. It is in the suggestions but I had no idea what it was for. Now I do. Thanks again!!

Fit perfectly...
Replaced the pump in my hot tub, was easy to swap. Friendly and helpful staff along with great prices. Highly recommended.
The pump works great but it does not come with seals or fittings to fit the drain plugs for the air hoses. The threads are none standard and tough to seal.
