I'm looking to get a new Hayward super pump. I'm not sure if I should go 3/4 or 1 HP. Hopefully you pros can help me out.
My pool is 10,000 gallons in ground. Hayward DE36 pro grid filter, Hayward gas heater 350btu.
The run from the skimmer is about 36ft and from the drain 54ft. The plumbing is 1.5" in the ground and 2" between the equipment.
The old pump is 3/4HP Hayward super. When it was installed (by previous owner) there was no heater. I thought it did the job but I never got to run it with the heater. I'm wondering if adding a heater will make that much of a difference in my pump needs.
FYI, when I was running the 3/4 HP pump the reading on the filter's gauge after backwash was around 10psi.
