one long pump run or several shorter

Hi
Is it "better" to run the pump say 9 consecutive hours or
3 periods of 3hours each

thank you

I say break it up if you can with a timer if you can.

In the summer I run a short cycle early in the day to hopefully push things towards the skimmer and equalize the temperature throughout the whole depth of the pool. The main filtering is later, when i have time to test and dose.

Yes, it is better to break up the run time if you can but three 3 hour segments is way too long. You might try three 1 hour segments and see if that works ok.

thank you all

Ok, would seriously like to reduce pump run costs but...

have been told that total pool volume (30,000) should be circulated once / day and that that takes about 8 hours
so not true, do not need to run 8 hrs to exchange total volume?

No it is not true. Read the link I posted.

BTW, what model pump do you have? 8 hours is pretty low flow rate for a 30k turnover.

have done
will do
outcome will be interesting (and cheaper)
thank you

WhisperFlo one hp
I think model is WTE-4

I tried to calculate time to turn over but failed

 

[mas985]

Probably a WFE-4. A WFE-4 will produce about 80 GPM on 2" plumbing for a turnover of about 6 hours.

Also, what is your method of chlorination? Unless it is manual, that will need some adjustment for the reduced run time.

ok, 6 is 2/3 of 9 so cost down to 2/3, nice

chlorination? Rainbow 320, set on setting #3, about 1/2 filled with tabs, and has the inlet at the top

 

[mas985]

I didn't mean to imply that you had to run 6 hours. I current run my pump 4 hours per day which is about 1/2 turn per day so you might be able to get away with 3 hours per day which is why I suggested 3x1 hour runs.

As for the chlorinator, because of the reduced run time, you will need to adjust that for more in less time.

is getting better and better, 3 is 1/3 of 9, lots of kWh saved
which is serious on Whidbey Island (near Seattle) as the pool is empty lots of the year

with Rainbow at 3 and half filled, there is plenty of room to increase

so why do I have a pool? was here when we bought the place
and by the way was green when we arrived, so green could walk on the water
now is clear, grandbabies will swim tomorrow; maybe me too for that matter

thank you again
