Interested in variable speed pump but have questions.

[Kevin_O]

Hello,

I have a in-ground pool that was installed in 2021 and would like to change from the original Hayward 115 VAC 1.5 hp single speed pump to a variable speed pump. Looking at options I see Hayward and Pentair are priced pretty much tree same but Harris is substantially less by about $800 to $900.

Can anyone comment on the Harris brand and their reliability?

I've heard others say to oversize the pump so that it can be operated at a lower speed. Does this make sense?

Thank you for any responses.

You have a link to the Harris pump?

No modern pool needs more than about 3/4 HP pump. Most all pool pumps are “oversized”.

A higher HP VS uses less energy for a given flow then a lower HP VS pump.

Look at the black and decker vsp too. Comes with a 5 year warranty.

Do you have 240V available at the equipment pad? The Harris (Doheny's) pump requires it, as well as most others.

If you have 240v to the equipment pad, I'd check into the Calimar 3hp VSP. It's one of the cheapest options available and works well.

Oversizing + operating at a lower speed results in lower noise levels and somewhat lower energy consumption, with the tradeoff of higher upfront cost.

The black and decker is the same as the calimar but somewhat cheaper. Make sure to purchase the extended warranty if you do get it.

Will do! Thank you!

The idea of having lower noise levels is a definite plus.

Needs 240v.

Very limited in the speed programming and ways you can program the speeds in a day.

I do have 240v to the equipment pad and with minor changes at the sub-panel it could supply 240v for the pump.

Don't forget the gfci part of the circuit when converting the pump to 240v you'll need a specific one that doesn't nuisance trip. It'll be of the Siemens variety and dependent on the wire your working with.

Just to be clear NEC requires all pumps 120V & 240V to be GFCI protected.

A pump is required to have GFCI protection installed when it is replaced.
