I went to Jandy website and found my pump, which had a link to pump flow rates, for run time calculations.

Here is the Jandy run time(savings) calculator.

Took down various rates, at various RPMs. Compiled a schedule to run for my 'off season' schedule on the pool.

Hope the math and run time works, if you know what you are doing and feel like checking, let me know your opinion.

Greatly appreciate any help here.

My pump detail (main VS pump) is in my signature.

My pool volume if 34,000 gallons (as measured during fill at the meter, adjusted for other use).

There are no trees in pool vicinity, I usually pick up 5 stray leaves per week, from the skimmers (total). So not much debris falls into it, at least now.

Rates/RPMs (not all, site shows from 4350 down to 600 in 50 rpm increments):

- 93.0 GPM at 3,450 RPM
- 74.1 GPM at 2,750 RPM
- 67.4 GPM at 2,500 RPM
- 59.3 GPM at 2,200 RPM
- 54.0 GPM at 2,000 RPM
- 51.5 GPM at 1,900 RPM
- 48.9 GPM at 1,800 RPM
- 46.1 GPM at 1,700 RPM
- 43.2 GPM at 1,600 RPM
- 40.5 GPM at 1,500 RPM

So I thought, put a schedule together, for off season (Texas winter use), for the pool.

The schedule would be as follows:

- Pump runs every day (7 days a week), from 8a-5p (9 hours a day)
- 1st line in schedule - Pump on and priming (8:00a - 8:05a - 5 minutes) - @3,450rpm - 5 mins x 93 GPM = 465 Gallons
- 2nd line in schedule - Pump runs at reduced rpm (8:05a - 12:00p - 235 minutes) - @2,750rpm - 234 mins x 74.1 GPM = 17,413 Gallons
- 3rd line in schedule - Pump runs at reduced rpm (12:00p - 5:00p - 300 minutes) - @2,500rpm - 300 mins x 67.4 GPM = 20,220 Gallons

**TOTAL WATER TURN OVER PER DAY: 38,098 Gallons**
- That is just over 4,000 gallons more than pool volume

That would give me just over 1 full turn over of water through the filter per day. Given that no one is much using the pool

- Would you consider this be an adequate schedule?
- Should I try to decrease rpm or run time, due to off season and no use?
- Should I stick with turn over of about 1.5 times pool volume per day?
- What would a schedule for summer (pool time schedule) look like, run times, volume turn over, etc?

Looking for advice and for a good starting point. My pool startup person put a schedule together, what they called 'their default new pool schedule'.

He told me that schedule runs pump 8a-8p (12 hours, every day, at rpm of 2750 non stop, which gives me turn over of 53,352 Gallons turn over through the filter daily.

I am kind of thinking he put this together as a cya procedure, cranking up run time and rpm, disregarding common sense, just to say 'hey, with our schedule pool looks clean'.

Thanks for advice from you fine folks.
