20k gallon in-ground
2 ports below skimmer basket. 1 to the pump and 1 to the main drain.
No valve to distribute suction between skimmer and main drain
1 valve to distribute return between 1 return port and all the other ports (not sure of the reason for this or the function it serves)
Hayward Super 2 Pump (1hp) w/ a new AO Smith B128 motor (old motor had worn bearings)
Auxiliary pump for cleaner
DE filter recently inspected, cleaned, and recharged
My wife and I recently bought an older house with an older pool. It seems to have been maintained well enough, but I don't believe I'm getting a sufficient amount of suction at the skimmer. Leaves and bugs will float right by the skimmer entry, but not get sucked in. It seemed to have a much stronger flow when we initially moved in to the house, but I admit I didn't do much with the pool other than empty the basket, skim the surface, and run the vacuum during the winter.
The pump is definitely moving water. There are no air bubbles to be seen under the pump lid or out the return lines. When the cleaner pump kicks on, the Polaris moves around properly and picks up debris.
I tried a drain king inserted in to the pump inlet. Nothing came back up the skimmer line and I could definitely feel the cold water from the hose coming up through the port. The impeller is free of debris as I checked it when I swapped the motor (same symptoms before and after motor swap).
