I have not had any suction from the main drain since I moved into this house last year. Since the deep end is 10' deep it seems like my circulation will always be insufficient only pulling from the skimmer and spa. I also have a persistent fine layer of dust/sediment on the bottom of the pool. The pool guy came out a couple weeks ago to replace a valve and said I would need to buy a "hydro control plate" in order to divert flow from the skimmer and force the pump to pull from the main drain. This is the part # he wrote down: http://www.aqua-man.com/row_num.asp?Ic=12635
Is this god practice to use the control plate to pull from the main drain while filtering, and just open the skimmer to vacuum?
