My pool builder is telling me that I need 3 additional main drains on for each water feature that we will be installing. So he is saying that each feature pulls the water from a main drain. I feel like I am trying to be up sold???
I think it is one set for each water feature which probably has it's own pump. Sharing MDs is not always possible given the flow rate when all the pumps are on.Again, I don't understand 3.....
It depends on local code but that would be the safest.But still have a split suction line with drain covers, correct?
