Works great!
This filter is working great! We had an old DE filter that was dumping sand into the pool. Once we installed this one our pool cleared up and is looking great. I highly recommend. Our pool is 30k gallons.

Love it
I cleaned cartridges with a garden hose, re-installed and are working great, the pool is clean and there is no noticeable difference in quality between the old sand and the new cartridge filter, water is very clear. The cartridge filter does a much better job at filtering and I do not have to waste water to back flush the sand filter. Love it.

This item was a great value. I had to replace my old obsolete unit and this fit perfectly and installed very easy. Hayward is a wonderful brand, we also love their pumps as well. Thanks PSU!<br>
