24x44 In Ground going in soon - question on pump setup

Postby swr084 » Wed 09 Jun, 2021 22:18

Pool planned to start construction in mid-July.

Below are some details:
-24x44 rectangle pool (3ft shallow/8ft deep
-Hayward Tristar VS 1.85hp pump
-Hayward S244T SAND FILTER
-1.5" Plumbing

will this allow enough flow?

I'm still researching, but its a little confusing

appreciate any feedback!

I'm not an expert on pool filtration and flow (Teapot is) but I would be inclined to increase the plumbing size to 2". Not an exorbitant amount in material cost but an advantage in flow and less resistance
I would also increase the filter size as I make it that your pool is 43,560 US gallons and the recommended size for that filter is 29,760 gallons which means the pump will have to work harder forcing water through with diminished filtration (slower is better)

thanks Denniswiseman
I was kinda thinking the same on 2" plumbing. Ill check into a bigger filter as well

Denniswiseman, where did you find recommended pool size for filters?

Also, Since I am going to 2" plumbing, that means the skimmers and returns will also be 2"?

thanks

I found a pool filter chart. 29760 gal is for an 8 hour turn on the S244T filter. I was shooting for a 10 hour turn, 2x a day. the other 4 hours I could have my VS pump run at reduced RPM

I was thinking about going with S270T2 filter, which is 2" plumbing, and can turn over 44400 gal in 10 hours.

But still need to know about 2" on skimmers/returns

thanks

Slower filtration is better every day
You could use 1.5" skimmers and pipe joined into a 2" tee before the pump but each one valved so the flow can be balanced. This would include the MD's which aren't really necessary
I would be more inclined to add more returns as the eyeball is restricted to about .75"

thanks again. Really appreciate the insight
Sorry..., but one more post/question(s):

If I have 2 skimmers and 2 main drains plumbed with 1.5"....and 4 returns plumbed with 1.5", I think I sould have enough flow rate to turn ~44k gallons over in 10 hours...? (approx 80 GPM)

The Tristar VS900 pump is 1.5", but according to pump curve, I can achieve ~80 GPM by varying the RPM (varying from 2400 to 3450), depending on whatever TDH I end up with)

And lastly, I think I should upgrade to S270T2 sand filter to handle a larger GPM (it also jumps up to 2" plumbing from the 1.5" of the S244T). I guess they use 2" to 1.5" reducers when they install plumbing

will it work to plumb the 4 intakes with 1.5", as well as the 4 returns?

and then 2" at the filter, or anywhere its flowing thru a single pipe?

I need to make a decision tonight if possible. Thanks

Not an expert on pool plumbing and filtration but my plumbing and heating experience says yes
So long as they go into the 2" separately and don't join up before
Best to take them separately back to the pad first except the main drain to prevent getting trapped
