Hi! I’m Markus Robertson, and water is my passion.
Five years ago, I graduated from the University of California-Los Angeles and was going to become a professional marine biologist. However, my fate had other plans for me, and due to family problems, I had to find a more stable and well-paid job. I had only one wish for my job to be connected with water.
During this period of my life, I worked as a sales manager at Olympic Pool & Spa Supplies. The job helped me learn everything about swimming pools and related pool equipment, as well as how to choose the best option and what to pay attention to.
Hi! I really like the Pentair SuperFlo pump. Will it be sufficient my 20 000 gal pool? Thanks!
Hello, Mason! Thank you for your question! The answer is yes, definitely. Since Pentair SuperFlo is a variable speed pump, you just need to figure out how much flow you need to turn your water over. The model is powerful enough for pools over 30 000 gallons. Real users’ reviews prove it works great.
Hello! Thanks for the review! What filter system can you recommend to complement Hayward Power-Flo LX Pool Pump?
Hello, Make! Thank you so much for your question! The filter choice will depend on the size and type of your pool. However, we can say that this pump has a recommended size for most sand filters. Hayward itself recommends complementing the Hayward Power-Flo LX pool pump with the ProSeries Systems sand filter. You can find a more detailed description and buy the product here.
Hi! Is it possible to install these Pentair and Hayward pumps both horizontally and vertically or the manufacturers require one orientation only? Thanks.
Hello, Dean! Thank you very much for your question! As far as we know, these Pentair and Hayward pumps allow one way of installation with a fixed position. But with Hayward, the manual contains instructions for reorienting the discharge for those who’d like to rearrange the pump.
Hi! Can I use any of these pumps for my above-ground pool (18ft x 48in)? Thanks.
Hello, Rorry! Thank you very much for your question! If choosing a pump for an above-ground pool, we’d recommend trying a quieter Whisper series by Pentair. These pumps are not the most powerful, but we don’t need it in above-ground pools. An optimal combination of silent work and decent power may please you a lot.
Marcus, thank you for the comparison. Hayward is my personal favorite here. But I’d recommend the MaxFlo model (more powerful/up-to-date in some way and costs almost the same money).
Hi, Gran! Thank you very much for your comment and sharing your experience with us! Indeed, Hayward also offers a slightly improved modification called MaxFlo. Our readers can find more detailed information on this and some other pumps in our Best Variable Speed Pool Pump in 2022.
I noticed the Pentair model is twice heavier than the Hayward. Is it an important moment? Who did installation, can you help? Thanks
Hi, Nikita! Thank you very much for your question! Yes, the weight is an important factor when it comes to the pump installation, its location and further usage. So please decide where and how you’re going to install your pump and mind it before purchasing.
Hi! Which model can you recommend for an inground pool (I have a 20×40 ft concrete)
Hi, James! Thank you very much for your question! If you own a residental pool, we’d recommend choosing a 1.5-HP pump, such as the Hayward Power-Flo and the Pentair SuperFlo. They’re better suited to the pipe size, water volume, and filter design of an average inground pool.
What are the benefits of several programmable speed pumps?
Hello Patrick! Thank you for your interest in pool pumps. Variable speed drive on pumps allows you to adjust the speed based on your needs. At low speed, you increase the durability of pool equipment, make energy and cost savings, and perform water treatment procedures to improve water quality. Conversely, you can increase the flow and enhance the performance of water equipment at high speed. Quiet operation mode is helpful while you are swimming without any disturbance. Three speeds of Pentair SuperFlo are sufficient for convenient pump operation.
Thank you for your comparison, it is just what I was looking for. Do you know the cord size of the Hayward W3SP1580X15? I have the 10” from the socket to the pool.
Hello Patrica! I am glad that you found helpful information. The cord size of the Hayward W3SP1580X15 is 6”.
