Return Plumbing Concerns

[pjt]

I have some concerns about the way the plumber setup my return pipes for my 25k gallon pool. It's currently setup as a 2" pipe from the pad (top left blue arrow) that tucks under a 2.5" skimmer line (at the red arrow). It then branches into two 1.5" pipes that form the ring manifold (blue arrows facing left and down) for the 8 returns.

Is 2" pipe on the pressure side large enough to supply 8 returns? Is it common/acceptable practice to tuck under a pipe? Is 1.5" plumbing standard for return loops? My instinct is telling me this isn't efficient, but I'm not a professional plumber.

Yes, yes, & yes.

8 returns is a lot for a 7,000 gallon pool. How do you have 8 returns?

pjt,

I see nothing wrong..

The fact that he is looping the return line around the perimeter of the pool, tells me your plumber knows what he is doing..

Thanks,

Jim R.

The 1.5" pipe is fine because you won't be trying to push high gallons per minute through return lines, you just want slow and steady. It is when you are trying to push high GPMs that you will start to quickly lose efficiency with a 1.5" pipe.

Yes, yes, & yes.

For my ~25k gallon build in progress in Texas. My signature (which I'll update) is for my California pool.
