I have a 15'x35' rectangular, 4' 6' 4' deep, 20,000 gallon gunite in ground pool with a single story solar system located in Northern California. I'm about to replace a Sta-Rite Max-E-Pro pump with an Inteliflo VS pump.
I'm looking for a suggestion for a programable solar controller to replace my current basic controller? Ease of programing in conjunction with the Inteliflo pump would be nice.
Also, I'm using a one season old Hayward Navigator vacuum pool sweep. The pressure gauge atop the filter reads 23 lb. as it always has yet the vacuum pressure seems much less than when originally installed and the sweep is barely moving about. The pump I'm about to replace is seven years old. Would a worn pump account for such a drastic drop in pressure or might there be an obstruction within the return plumbing to the pump? Is there a way to check this or somehow snake the return?
