Response to I just bought a house with a ~35455 gallon rectangular inground pool. As far as I know, the pool is 13 years old with the original equipment. It has a Pentair 7-177474-01 1 HP single speed pump installed with a Pentair FNS Plus DE 48 sq ft filter. The filter appears to be appropriate, but I'm looking to make the pump more energy efficient as it runs 24/7 with possibly switching over to salt sometime soon. It looks like I need to move 50 gpm for 2 turnovers, would this be a good replacement?
