I have a couple of question about the plumbing for the returns. They are plumbed with 1.5" PVC and connected as shown in the attached picture. The pool is 6' x 35' gunite pool (~28k gallons) with a 7' x 12' tanning ledge. The pump is a 2 hp variable speed.
1. First, I was told that the returns would be plumbed in a loop, but this is how they were run. When I questioned the PB about it they said it would be fine this way because the eyeballs are 3/4" and will neutralize the line. Should the loop be plumbed in to help maintain the pressure on the returns furthest away from the equipment?
2. The return at the top left of the drawing was run part of the way down the wall of the gunite shell while all of the others were run around the shell and just a straight section of pipe is sticking through the shell. I would think the last return should have been run the same as the others. I would think that you would want the minimum amount of piping/connection points inside the gunite, but I wasn't sure if this is acceptable.
Thanks for the replies.
