Is 3" plumbing worthwhile?

[pjt]

I'm finalizing my plans for a new build. Should I ask for 3" pipes (instead of 2.5") for the long runs of plumbing between the pool and equipment pad? Do any pumps/filters support pipe diameters greater than 2" or are reducing fittings required?

No, you will not see any operational difference if 3" is used instead of 2".

What flow rate are you planning for?

What is the distance from the pool to the equipment?

What are the details of the pool?

I plan to run the pump mostly at the lowest flow rate possible, just enough to run the SWG. It's ~50 feet from the equipment to the pool. I'll be using a Pentair InteliFlo 011028 pump. Suction side will be two skimmers (no main drain). Pressure side will be 6 or 7 returns. Pool is 40' x 20' and 4'/5'/4' depth (~25k gallons).

P,

Let's wait and see what James has to say, but I would say that anything bigger than 2", for your pool, would be a waste of time..

Thanks,

2" from each skimmer to the equipment should be fine.
