I just purchased the powerFlo LX 1.5 for my above ground pool, but my old sand filter can’t handle the pumps pressure for more than a couple minutes. What is the smallest compatible sand filter for this pump?

A  Answered on 1/7/2021 by InyoPools Product Specialist Hector F.

Hello, on average a 1.5 hp Hayward PowerFlo LX pool pump matches well with an 18-21 inch diameter above ground pool sand filter. 

?     Asked on 4/15/2020 by Derek

What is the best pump for a 33rd round above ground pool?

A  Answered on 12/2/2020 by InyoPools Product Specialist Megan C.

If you are not restricted to use a certain pump as many of the pump/filter combos by Pentair, StaRite, and Jacuzzi will require the original pump that was sold with it to make the connections from the pump and filter. A 1.5HP or 2.0HP is a great choice (For round above ground pools over 24 ft.  (pools with more than 15.300 gallons) use a 1.5 HP pump.) The Hi-Flo Above Ground Pool Pump 1.5 HP 115V with CORD & 24 HOUR TIMER - PD11506-TIMER (Standard 3-Prong Plug) is a very nice pump that would work great for a 33' round pump. Here is the link to the other above ground pool pumps we offer http://www.inyopools.com/productlisting/pumps_aboveground.aspx

Looking to replace the capacitor in this motor, but I don't see it on the part list. Before taking it out, is there any way to know what capacitor it uses? Thank you.

A  Answered on 7/26/2019 by Industry Professional

sorry but no. You will need to at least look at the capacitor to get the mfd rating to match it up. You should be able to get the information without removing. If removing, be very careful & you will need to discharge the capacitor after removing the leads as it can still hold voltage.

Bought the Haywood above ground Power Flo LX. It has no ON/OFF switch. How does it work? How do I turn it off and on?

A  Answered on 5/29/2019 by InyoPools Product Specialist Steve M.

Dolores, the Hayward Pool Products Power-Flo LX 1HP, 115V, Single Spd. Pump is shipped less the On/Off switch. The On/Off Motor Switch - SPX1500S8 would be compatible with the  Hayward Pool Products Power-Flo LX 1HP, 115V, Single Spd and is available for individual sale. 

  • Commented on 5/29/2019 by Product Owner

    Will it work without the on off switch? I have never ever heard of such a thing. Selling a pump without the ability to turn off and on.

    • Commented on 6/6/2019 by InyoPools Product Specialist Patrick P.

      Dolores, The pump will work without the switch it will always be running when plugged in. Most pool owners purchase one of these Pool Pump Timers that the pump plugs into, you then set your timer to have the pump turn on and off at certain points throughout the day.

When wiring the receptacle or plug-in for the pump, is a 20 amp breaker sufficient or do I need a 30 amp breaker?

Hi. A 20 amp breaker will be sufficient if this pump will be the only equipment running on that breaker. If not, then a larger capacity breaker is required.

Hi, Gary. Yes, a 1HP pump is sufficient for an 18' above ground pool. The pump you have has a twist lock power cord so you will need p/n SP1580TL.

I have a 6 year old Hayward Pump Power Flo LX model #S48E48A04 HP 40GPM It does not have a basket. It is being used in a water feature and supplies enough water. I would like to replace this unit with a new Hayward product. Either a new Power Flo LX or the Power Flow II. What new model would be the equivalent? SP1580, SP1775? Thank you

A  Answered on 7/3/2016 by InyoPools Product Specialist Alex V.

Don, If it's a Power Flo LX, the SP1500 series Power Flo will replace it. The SP1580 would be correct if you are replacing a 1HP pump.

I currently have a Power Flo Matrix SP 1510-Z1-XEHC but it just died on me. I don't seem to find a replacement for this exact pump. I'm wondering if the listed pump would be ok as replacement. My current pump connects on the side to the filter. This appears to be on top. Can that be turned so it connects properly or is there another part that I would need. Thank you for your help.

A  Answered on 8/20/2015 by InyoPools Product Specialist Lennox H.

Hi Mary, The Hayward Matrix 1 HP w/ Switch Motor (SP1510Z1XE) will be the correct replacement motor. The Power-Flo LX 1HP, 115V, Single Spd. Pump discharge can be rotated. Instructions on how to rotate the discharge can be found in our How To Rotate the discharge port on your Hayward Power Flo Pump.

A  Answered on 7/24/2015 by InyoPools Product Specialist Hector F.

This model does not have the twist lock plug and is suitable for a 15 by 30 ft, 52 inch pool. You just need to be sure that the gallons per minute rating for the pump is compatible with the filter that you have. The model of this pump with the twist lock is SP1580TL.
