Trying to understand.

[Adamf79]

I have a year old pool that was set up by pool builder. I’m now getting more in to this and trying to fine tune my pool equipment. I do need some help understanding this.

I have Pentair super flow VST pump, Pentair tegalus ta60d high rate sand filter, cmp variable speed chlorination. Looks like I have two bottom drains and two skimmers going to the pump. I have 3 1.5” pvc coming in. Then I have 4 returns. I have Rheem heater and I have intelliconnect working all the equipment. Pool hold about 17500gal of water

I recently put in inline flow meter and was able to record 60gpm at the highest speed of the pump. Is that good or ok?

I’m trying to safe energy and want to run my pool 24 hours. Currently my pool runs @3100rpm in the morning for 2hr then it goes to 2500rpm for the endure day and it will drop to 1000rpm for the night.

If I understand this correctly I will need about 30gpm to turn over the pool in about 8hr. Doing this I can lower my pump speed lower at the day time to get there or should I do it at night? Does my filet has to have a minimum gpm to function correctly? Also same goes with my chlorinator.

Any advice would be gladly appreciated.

Thank you!

You run your pump for a purpose. Mixing chemicals, filtering, heating, skimming, etc.

I have a cover, SWCG and Heater. I run 24/7. 2200 RPM at night to get the heater to have enough flow (35GPM), then run 1400 for the SWCG the rest of the day, don't really need skimming because of the cover.

For the SWCG, lower your pump speed until it turns off. Add 200rpm and that is min flow for your SWCG. 200 gives you room for a dirty filter.

Read your heater manual to figure out the minimum flow required. If you run your heater all the time, then set your pump 200rpm over minimum flow for your heater.

Make sense?

I generally follow what PoolStored stated. I also run my pump at higher speeds a couple times a day to help skim floating debris (I run a 3000 rpm for 30 minutes twice a day before when I am likely to be using the pool). This also helps purge air out of the pump skimmer basket (sometimes I don't get the pump cover on perfect and there is a small air/suction leak, helps to ensure the pump doesn't end up sucking air).

Thank you both for replaying. I did look up my heater it calls for 30gpm. I do not have salt cell I have a chlorinator that works with variable speed pumps. I was able to find out that it requires at least 20gpm function. I do have an automatic pool cover. So I could get rid of my morning skimming run. I also read somewhere that 1.5 inch pipe should not exceed 45gpm is that right?
