The pool will have a waterfall that is on a separate pump. One PB has the source (suction) from two floor drains. There are already two floor drains tied into the filtration loop...so the pool would have a total of four drains. Another PB has the source from an inlet on the wall of the pool ... with the appropriate anti-entrapment cover.
Is either a "better configuration"?
What are the advantages/disadvantages of each configuration?
