I have read here it's better to plumb the skimmer and main drain separately to the equipment pad, anyone know why this is recommended?
Returns, how many? Where should they be placed? I have read the wall returns should be about 18" below the water surface. How many on bottom? One of the PB wants to put 4 returns in, 3 on the walls one heat return on the bottom. The other builder puts 3 heat returns on the bottom?
Confused, is there a better design?
