This is my first post and my first question - lots of info on the forum
We are installing 18x36 in-ground pool (20000 gal, 613 sq. feet) with Hayward EcoStar Variable Speed Pump.
The pool will have no main drains as stated by the PB.
Here are my questions, based on the above specs:
1. How many skimmers should there be? Is more needed since no drains?
2. How many returns should there be?
3. 1'5'' or 2' pipes?
