Hi guys (and thanks for reading)
I'm a new pool owner wondering what RPM I should run my pump. I have a Hayward Tristar 1.8HP VSP that can run between 1000-3400 RPM, but this thing is pretty loud at the high speeds and I don't know if it is necessary or cost effective. It is currently set up to run at 3100~ RPM for 4 hours then about 1700~ RPM for another 4 hours from midnight to 8am.
Does this seem about right or is it overkill? Also when heating the spa does it really need to be at maximum speed, too?
Some more information:
The pool is roughly 11,000 gal, spa is around 1000 gal. 400k BTU heater, pipes look about 2.5 inch outside diam. 400sqft cart filter. Not sure what the TDH would be for the whole system honestly. Oh and this is in Phoenix, AZ.
Appreciate any thoughts / advice! And let me know if I need more info
