A 1 1/2 HP pump could be under powered for the spa if it has more than 4 jets and it might be for the floor cleaner as well. The manufacture of the in-floor cleaner should have given you a design to follow. If you do need more power, then it would be well advised to look at a 2 speed or VS pump.

If your PB complains, tell him you would be willing to go with a single speed pump if he pays the electric bill every month. :-)

You have anther post about a negative edge design. If this is the same builder, and he recommends a singe pump design for a pool with a negative edge, thank him and send him on his way.

I find it hard to believe he has designed others successfully. He also hasn't been educated to understand how beneficial two seed and variable speeds are when it comes t energy savings. If he has been, what else has he been less than forthcoming with?

The pool filter system should be separated from the negative edge. The pool filter system can run a spa but not a spa and the negative edge at the same time. Most negative edges are visible in the yard and looking pretty is important.

Negative edges typically need between 10 and 20 gallons per foot,, depending on the back side of the edge and the effect desired. Spilling straight down does not require the same amount of water as a sheer arcing away from the wall. Negative edges should be driven by their own pump. Which pump to use here will be dictated by the edges design parameters.

For the pool, we need more information about the design. How many spa jets, plumbing size, how dar away will the equipment be, and any other details you can think of will help us to help you.

Thanks, Scott. It is not the same builder however these questions and all of the answers I hear are helping me to decide whether or not the builder I will select has credibility. It's part of my process in selecting a builder. Also I have been reading these postings and learning a lot. What has really surprised me, being a sales professional myself is how little the PB sales people listen to what I want in a pool. I guess it shouldn't surprise me. I asked the last guy if he had the notes from our previous meeting because, as he was explaining the pool he designed, he had missed half the things I had told him I wanted. They were all in his notes.
