Getting a 20K pool installed. 36x18 (depths are 3.5 to 7 ft)
Have some questions on piping and flow:
Current proposed setup with Hayward EcoStar pump:
Input:
- 1 skimmer, 2" return pipe (no main drains)
Output (2" pipe out of pump, split to returns and sheer descent):
- 4 returns (1.5" pipes)
- 3x3ft = total 9ft sheer descent (one 2" pipe feeding all 3, split at the end into 3x1.5")
- Will have a valve to switch between returns or sheer descent, dont plan on running both at the same time.
Are the piping widths sufficient for the required flow?
Should I be upsizing any of the pipes (in particular should the skimmer line be wider than the output?)
Logically i'm having a tough time understanding how a 2" input pipe can feed all the outputs without some serious pressure differences.
What would you change in this scenario for sizing? Also just the sheer descent sizing indicates I likely need around 108 gpm though the pump manual recomments max flow of 80 gpm with a 2" pipe.
Help is much appreciated, thanks!
