I tried researching myself, but I do not have the skills and experience most of you have. I'm having the following pool built and need some advice.
IG Sports pool only, NO spa
Depth: 3.5' x 5' x 3.5'
L x W: 28' x 12.5'
1 HP single speed pump
420 Sq. Ft. cartridge filter
400 K BTU Natural gas heaters
All above equipment is Pentair
2 3' length sheer descents positioned 2.5' above pool water line with 2 HP single speed dedicated pump.
Filter/Heater pump is 20' – 25' from pool. Water feature pump is 30' – 35' from the sheer descents.
All piping is 2".
1. From my research each pump seems to be oversized. Am I correct? The builder suggested the sizes, but I believe a .75 HP main pump and .75 feature pump would be sufficient and save a little money. Would it be better to run the water features on the main pump, possibly use single variable speed pump?
2. Is the filter size too large?
3. Any additional advice on Price / Design / Equipment / Piping Size etc. would be appreciated.
Thank you in advance,
