    New Pump Advice Please.

No floor drain. 1 1/2 piping. Orig pump .75 hp. Last 15 yrs using old 1 hp ITT Marlow found at yard sale. Impeller needs rebuild but thinking of just replacing due to efficiency/parts availability.
    Any suggestions?

    I would go with a small two speed. Here are a few of my favorites that would work well with your setup:

    Pentair SF-N2-3/4A (115v)
    Pentair SF-N2-1A (230v)
    Hayward Super Pump SP2607X102S (230v)

    18'x36' 20k plaster, MaxFlo SP2303VSP, Aqualogic PS8 SWCG, 420 sq-ft Cartridge, Solar, 6 jet spa, 1 HP jet pump, 400k BTU NG Heater

    Energy costs. Low speed uses about 75% less energy than high speed or a single speed pump. However, it has about half the flow rate so you need to run it twice as long but you still net a 50% reduction in energy use.

    I find that I'm running my pump way less than my old single speed. I bought a dual speed 1 hp and I only use high speed when manually cleaning.

    I also bought a timer and I run low speed 10 hrs a day

    I have a 15k L pool

    No problems with Algee yet

    I do swim every day.
    Approx 74,000 liter inground vinyl pool 12x32, laser 225 sand filter, Hayward 2 speed pump + old pool heater.
