Looking for suggestions as to how to locate a leak. I've so far been able to determine that its on the suction side of my skimmer line. When the skimmer is off the pump will maintain prime and work great. As soon as I start to turn on the skimmer I start losing prime and over a very short period of time the pump basket emptys.
I've checked and increased the water level and it didn't have any effect and it appears that the weir door is operating properly.
Where should I go from here. Is there some way to easily check the piping short of pressurizing the line?
