I'm preparing to do the plumbing for my inground steel wall pool. Everything I read says to try and eliminate 90's but every picture of pool plumbing I see has a 90 come up and then a 90 go over to pool for returns etc. Wouldn't it make more sense to 45 up and then 90 over to reduce at least 1 90. Or does the 45 up increase the likelihood of settling and pipe. Leakage? Any help in regards to plumbing a pool would be appreciated. I plan to use 2 inch almost everywhere, and run home runs to each skimmer, and main drain, and then split my 4 returns off of 2 lines back to pump. System will have 2 skimmers, and a main drain. Plus 2 wall reruns and 2 step returns. I will also have 1 small sheer decent and 4 deck jets,but will plan on using 3 ways to divert pool reruns to those, when I plan to use them. Probably not very often....thanks in advance. My pump is a Pentair intelliflow 1.5 hp.

I did mine with 90's going straight down like the 1st pic...except I did a seperate run for each. My reasoning for doing it this way was that after the plumbing is complete and you backfill the weight of the fill and your deck material of choice is pushing down on the return and if you have a 90 going straight down it's supported. I have lots of 90's in my pool and it runs just fine. Mind you I did try to plan as best I could...but they can't be avoided.
 
F,

You will never be able to tell the difference in two 45's and one 90 in actual operation.. Unless you had a hundred of them, or trying to force massive amounts of water through them, which is something that just won't happen with pool returns.

If you have an IntelliFlo you will be running it slow most of the time.. I run mine at 1200 rpm...

As a side note.. If you have an IntelliFlo, it is normally a 3 HP pump.. Did you mean you have a 1.5 HP SuperFlo VS???

Thanks,

Jim R.

Ok thanks for the info, I wondered if that was the reason...now I know. That does make sense
