No, the deck is level with the pool and the pump is mounted probably 30ft from the skimmer. The pump did run dry a few times (leak) and I think that took a toll on it. I wanted to get the Northstar to try and save some electricity and hopefully get more silent operation. Aside from that the housing of the pump gets so hot I can't even touch it. The pool company that installed it says it's normal

I was thinking since my total head is about 50 (filter pressure of 17psix2.31= 39.27 + 10 for an average suction since I can't measure it = 50) If this is correct then I am thinking the HAward 3/4 HP full rated would be adequate since it delivers 70 gpm at 50ft.

The 1/2 HP delivers 50GPM at 50 ft but that may be pushing it with the spa spillover and stair jets. Then again I have no idea what I am talking about

Any opinions?
Thanks,
J.
