Jetted tub didn't work when I bought the house. Warrantee company wanted to go through the wall to repair... UH .. NO... that is why there is an access panel! That would have cost me WAY more than this pump. It was slightly different than the pump I had (slightly taller and just a little offset in front-rear distance), so I had to do some minor PVC work (I took out a small section of PVC and put in 2 x 22.5 degree angles to move the pipe slightly into alignment - maybe this will help you too!). Now my tub has jets. The hardest part of putting it in was the small access, but it can be done. The pump turns on and off via the air hose connection and has a normal 3 prong plug. Arrived on time. Recommend.
