I just purchased a 10 year old house with pool here in Florida.
Pool Type:
In-ground concrete with no spa or water features
Pool Capacity:
9,000 gal.
Pump:
Sta-Rite Max-E-Pro
Pump Motor:
1 HP single speed
Filter:
Pentair Clean and Clear 100 sq. ft. cartridge type
Minimum Pipe Size in System:
1.5"
__________________________________
Since the water pipes are only 1.5", I read that this pipe diameter limits water flow to 42 GPM. Even though both my 1 HP pump and my Pentair filter is capable of flowing greater than 42 GPM, I am still limited do to the 1.5" pipe size.
At 42 GPM (2,520 GPH), it should only take 3.6 hrs to turnover all the water in my 9,000 gal pool.

Here is my question ... Am I right in thinking that a 3/4 HP motor with a properly sized pump impeller would also be capable of flowing 42 GPM? ... If so, using the 1 HP single speed pump motor I have now serves me no advantage over a 3/4 HP single speed motor other than a larger electricity bill.
BTW ... I was thinking that a 2-speed pump (while advertised as using less electricity) might not save that much more money since when it operates at the lower speed, it will just need to run for a longer time in order to turnover all the water ... and there goes the savings
Thanks,
Ron
