First pump I ordered on here from another seller (was cheaper) never even showed up. Ordered this one the second time. Came quickly and real easy to install. Installed on a lifesmart LS100 series 200 gal hot tub. Correct wiring diagram even though it didn’t come with a new ground ring to crimp onto ground wire inside box. No biggie they are under $1. (do yourself a favor and use 2 wire nuts and electrical tape them once they are twisted on. The crimp caps that come with it are sufficient but if you ever have to service it later in you’ll end up having to cut the wires.) as well as perfect match to existing pipes. Lined up with existing bolts that were there for oem pump. Stronger than oem pump as it was only 1hp. This one is 1.5 and pretty dang quiet. Only took about 12 hours to heat water from 67 degrees to 90 degrees. Keep in mind half that time it was in the sun and was around 90 degrees outside.
