Just waiting on the pebble sheen but I have a question about the equipment. I'm not sure my pool builder sized equip correctly and I would like some other opinions.
I have a 110' perimeter free form in ground w/ 8' spa. The pool has 4 returns and the spa has 9. Together the're about 27000 gals in volume. 2" plumbing.
On the pad I currently have a 2hp Hayward Tristar and a Hayward DE4820 filter. I've convinced the PB the pump is way to powerful and he's going to replace it with a 1-1/2hp Tristar. But I'm still afraid the DE filter is too small. The DE4820 handles 96gpm and the 1-1/2 tristar outputs about 130gpm
If the combo isn't right i have two choices:
1) Should I up the filter to a DE6020? or
2) drop the pump even further to a 1hp?
If #2 is the right answer, great, I'll run the filter cycle longer and it will also mean lower electric bills, but will that be enough gpm for all my returns?
How much does a gpm a return output? Somehow 12gpm pops into brain.
