    Help with pump decision ...

    Hello all,

    This is my first post, newbie here. I am replacing a 15 yo. old Hayward Super Pump II that is 2.5 hp. I was considering going to a Pentair super flo 2 speed 1 HP pump.

    I think my pump is oversized to begin with...i have a Hayward 48sq. DE filter and an in ground Spa that waterfalls into the pool.

    Would this new Pentair super flow 2 speed 1HP work? I found one on Amazon warehouse for only $350.

    My other thought would be to take advantage of the electric company rebate and buy a Raypak variable 1.5 hp for $500 and get a $100 rebate. Total $400.

    I lean toward a 2 speed and eliminate the electronics. But is 1 hp good enough?

    Is that pump used to run your spa jets? If so, do not downsize or the jets will get weak.
