I currently have a 1.5 hp Hayward pump with 1.5" ports. Can I up grade to a pump with 2" ports with causing an issue with the rest of the plumbing.

Hi, Robert. Yes, you can install a pump with 2" ports without causing an issue.

Hi Randy, This pump has a 2 year warranty. For most standard pools on the high speed setting this pump will output roughly 80 GPM

I have a 1.5 hp Hayward northstar, will this pump be a good replacement for my original?

A  Answered on 4/7/2020 by InyoPools Product Specialist Patrick P.

Hi Anthony, Yes this 1.4 HP Variable Speed would be a great replacement for your 1.5 HP Northstar. You will save a ton your operational costs by going to a variable speed.

Do you guys sell extended warranties? If I install it myself does that do anything to the 2 year warranty?

A  Answered on 4/8/2020 by InyoPools Product Specialist Lennox H.

Hi, Anthony. We do not offer any extended warranties. If the pump is self installed, you're still eligible for the full manufacturer warranty.

Our old pool pump was loud and inefficient

Written on 5/26/2020 by Guest

After carefully researching VS pumps I decided on the Waterway PD140. The utility company provided a $350 rebate, the warranty is 2 years even with a DIY install, and it’s made in the USA!

The pump showed up in a very solid box with tons of formed foam. Adapters were provided for my 1 1/2β€œ pipes and the variable height for the base were very helpful for the install.

Wiring was easy considering my previous pump was 220 just like the new pump is pre wired. Make sure you have a 1/2” seal tite connector - the pump does not come with one.

The pivot attachments on the pump are great and make plumbing it easy with the flexibility.

The new pump is quiet, powerful and doing a great job on our 28,000 gallon pool and spa. Our old pump was a 1 hp and our system ran at 20 psi - same as the new pump in 3450 rpm....

The only improvement that I would like to see would be an easy on - off override to continually run for heating or opening.

This is a great pump and I highly recommend it!

Defective unions not molded fully so the threads weren't tightening fully.

Written on 5/4/2020 by Guest

Installed new unions that. were sent to me replacing the defective ones. Defective ones couldn't be installed in the pump. So it was just installing the new ones that were sent and connecting the hose from the pool and the hose to the filter.
