What do you mean "calibration"?

The tech is suppose to calibrate the pump to run at off peak hours. Usually really counts in the summer when demand is greatest. This is the main reason NV energy is giving these rebates is really for their own benefit. They do not have to buy power from other sources during peak demand and pool pumps use a lot of energy (second only to the A/C unit). He is also suppose to make sure you pump does has settings so it can run enough hours at the lowest possible speed to turn the water over once. They are suppose to fill out all the paperwork and submit that so the rebate will be valid. They may have changed the rules, but this is what I was taught in 2014 when I went to the classes at NV energy.

He did the paperwork to fill out the rebate thing. But he said 2500 rpm is necessary to use between 8am and 3pm. I was too happy because I want it to run at night because it is cheaper (7pm til 1pm). And I wanted 750 rpm instead of 2500 rpm.

The tech guy said 750 rpm is too low and cause clarity issues. Is it true?

Depends on the size of the pump, size of the pool, your filter and your plumbing, but 2500rpm sounds too high and 750 too low.

For me, something around 1700rpm is the right rpm for the normal filtering speed. That gives me 30gpm flow rate, power consumption around 275 watts, and eight hours of run-time per turn. This is for a pump that tops out at 3450rpm.

The size of the pool is 15 x 32

From what i've learned from Pentair, the lower the rpm the better the filter works. Don't quote me on this but this is what the Pentair reps told me on one of their company classes.

One thing that he didn't mention is how large diameter is his intake and discharge pipes. Some older pools use 1 inch to 1 1/2 inch and the lower RPMS are actually better. I've got a pool that has 1 inch pipe front and back, and we run the pump at 800 RPM 12 hrs a day with no problems (it has no solar, cleaner or spa of any kind)
