      Hi Jonathon, the replacement 3/4 hp motor for your Hayward Max Flo pool pump is the UST1072 which is an AO. Smith who manufactures Hayward motors. You will also need a Hayward Max Flo seal kit when replacing a motor.

Hi. What pump/filter would you recommend for a small rectangular inground pool with an estimated 6500 gallon water. Thank you!

A  Answered on 11/4/2020 by InyoPools Product Specialist Hector F.

Hello, so there are a few variables to consider when selecting pool equipment. Here are two guides called "How to Size a Pool Pump for Your In-Ground Pool" and "How To Size a Pool Filter" that should help with that.

I have this pump Sp2705x7, it has a 3/4 HP motor, what should I get for a replacement, trying match the existing pump as close as possible to minimize changes to my pvc


A  Answered on 3/3/2020 by InyoPools Product Specialist Lennox H.

Hi, Ted. You can use the Waterway SMF 3/4 HP Max Rate Pump - SMF-107 as a suitable replacement for the Hayward MaxFlo II Pump - SP2705X7 model pump.

The part number we have CF11-N1 3/4A other number is a 1-17-F04/ 34-3232 will this pump work on this exchange?

A  Answered on 5/13/2017 by InyoPools Product Specialist Lennox H.

Hi. Unfortunately, this pump will not work as a replacement because it's an above ground pool pump. The Pentair Challenger 3/4 HP 115/230V UR Pump - 343232 is the exact replacement.

I want to use this to replace a SP1575, for which the discharge had been rotated to horizontal. Can I do the same with this pump, via removal/replacement of the pump/motor bolts?

A  Answered on 2/16/2017 by InyoPools Product Specialist Scott W.

Yes, you are able to rotate the wet end to make it a horizontal discharge.

This pump says it can be used for small inground pools,how small is small and can the cord from my old Hayward 3/4 pump be used. Thanks

A  Answered on 5/14/2016 by InyoPools Product Specialist Andy O.

Jeanne- The size pool that you can use the Hayward Power-Flo II 3/4 HP Single Speed Pump Part # SP1775 would depend on the Average feet of head in your pool.
