Hi everyone, I'm brand new to the forum here and was hoping someone could give me some good input on my question.
We are redoing an above-ground pool that we have not ever used. The pool is 24'x15' (rectangular), and the walls are constructed of 3/4" treated plywood, so it's pretty easy to change some things around since we are putting new wall foam and a new liner in to give this pool a fresh start. The original owners of this house installed the skimmer and return jet approximately 3 ft from each other, so to correct this and help with the proper flow I plan on repositioning some stuff before the new liner goes in this weekend.
I've already bought a new skimmer and relocated it to the center of one of the 15' long walls. I now plan on installing two return jets on the opposite end of the pool to help push the water in the direction of the skimmer. The pump is on the side of the pool that has the skimmer, so I plan on running PVC piping to the new two new return jets on the opposite end of the skimmer/pump. The old return jet that I'm discarding had a 3/4" outlet.
The two new jets have a 3/4" outlet. So considering the length of the run of the pressure side that is going to have to go the jets (let's say approximately 37' to the furthest jet), what inside diameter of schedule 40 PVC pipe would allow for the optimal flow and pressure to the jets without being over-kill? I was thinking maybe about 1 1/4" might be good but I'm no expert in plumbing so I would really appreciate some feedback on what you all think may be a good choice. Thanks so much!-Andrew
