I need help in computing the Galons per minute pumped by my Century A.O. Smith B858 56Y Square Flange 1-1/2 HP Full Rated Pool and Spa Pump Motor. I have two skimmers and a main drain
Skimmer1=50’
Skimmer2=50’
Main Drain = 56’
Average Head = 52’
Once I find out the GPM I can complete the formula to calc how long to run the pump every day on my 24,000 gallon pool.
Wow, I still have a lot to learn about this stuff. I just moved into a house with a pool and have no history of the equipment or use of it. I may still need your help in figuring out the feet of head. I’m attaching photos which may help you to guide me in figuring it all out.
Here is an overview of all the 1 1/2" pipes going in/out of the pool equipment shed
I have two skimmers each about 50’ away and about 1’ higher in elevation than pump. I have no idea how many 45 or 90 degree angles there are on any of the pipes.
I have TWO main drains in the deep end of the pool so that would be about 7’ below the pump (=8-1).
There are two inputs between the waterfalls at the deep end of the pool - see image
I realize this is sketchy but I just want to know how long to run the pump in swim season. And can I just run it a couple hours a day in the winter when not in use and to prevent freezing - I live in a warm climate in Athens GA
