Suction side leak . . . Found in Pump Drain Plugs

[PoolDoc]

That's an interesting technique! I think that would have worked on some of the leaks I've hunted!

Problem solved. I tried the shaving cream detection technique, and found out that my air leak was coming from both of the drain plugs on the pump. When I unscrewed them, only one had a gasket, the other had a small amount of dried up plumbers tape. So I went to the local pool store and bought 2 new gaskets, which looked very different from the one existing gasket, both in color and shape. I've had the new gaskets in place for about 7 hours and have no air in the filter. Thanks for all the help.

Great to have the problem solved. That shaving cream trick may help somebody else. Thanks for reporting back in.
