I have a concrete slab and pool screen about to be built to house a spa.
They were talking about a 2 " slope. The manufacturer said 1 " was okay . BTW the slab is 25' width x 20" Long.
The manufacturer also said to place the skimmer/filter on the low side which is not really possible.
Is 1 " really going to make much of a difference?? What is the issue?
Thanks
