    Cool Two Speed Pump......Recommendations Please

    So the motor of my Hayward SuperPump went out and I'm thinking of switching to a 2 speed pump (to save electricity costs) instead of just swapping out the motor. I currently have a 1 hp Hayward SuperPump and it seems to work just fine (or it did). My lot is flat and the pump pad is roughly 25 feet from the edge of the pool. I have 2 skimmers, 3 returns, and a main drain. I also run a PB4 booster pump for my Letro Legend. After looking online, I found the one linked below. Would this be the proper replacement for me? Seems like a good price and well regarded. I guess I should just stick with a 1 hp, correct?

    Yes, 1hp is plenty. The Superflo is a good pump. It will save you lots of money. It will use about 25% of the electricity on low speed.

    Re: Two Speed Pump......Recommendations Please

    So I just spoke to a guy at a pool store and he said 1 hp isn't enough for a 30k gallon pool. He said 1.5 hp would be the minimum he would recommend. He said it would improve clarity greatly. I told him I've never had issues with clarity or anything else running my current pump. So is this guy just full of it?

    You started that sentence with "So I just spoke to a guy at a pool store " The answer to any question after that is "Yes, they have little to no idea what they are talking about"

    Only you know your pool. As long as your pool was staying clear as glass using an older 1hp, then you will be just fine with the 2 speed option you selected.

    Much appreciated. Is there anything I will need to purchase besides the pump I linked to? I'm guessing I may have to reroute some PVC pipes but I can get that from Home Depot. Anything else I need at all?

    1hp is more than plenty. I would get a set of unions. Make sure you use schedule 40 plumbing from lowes/HD and not vent/waste pipe.

    Well of course the unions on Amazon aren't Prime and I can't get them tomorrow with the pump.....trying to get everything so I can swap out this weekend. Is it likely I can reuse the unions from my SuperPump?

    Home Depot or Lowes or a local plumbing supplier like that should have them.

    Re: Two Speed Pump......Recommendations Please

    I'm curious about what I will need to do with regards to my pool cleaner (Legend with PB4 Booster). Can I just leave the pump on low at all times? My cleaner is currently on a Intermatic timer so that it comes on for an hour or so each day. Am I going to have to put some type of controller on the pump so that it switches to high while the pool cleaner is on?

    You'll have to see if the cleaner operates efficiently with the pump on low. My pressure cleaner did ok with my variable speed pump at fairly low rpm. If not, international makes a 2 speed pump timer that can switch it to high. I got to a point with my cleaner that I just ran it manually when it needed it and quit running it daily on a timer. Now, I have a robot and life is better!

    I think the unions might fit the Pentair pump.
