That's why I love VSP as much as the power savings. When I installed my Tristar I went back outside and was upset thinking It quit running but as I got a few feet away I noticed the pressure gauge was at 5psi@monfresh @TadPool Finally got this pump up and running. It has only been a couple weeks but so far very happy with it. The quietest pump I've ever personally seen (others were Hayward Eco Star, a chinese no-name variable speed, Jandy 2 speeds) and plenty of power for my four spa jets. I could barely tell it was on standing next to it at 1500 RPM (like, seriously I thought it hadn't turned on). Very quiet even at 3000 RPM.
