Hi all; Another often overlooked leak is on the inlet and/or the outlet pipes. Check carefully for leakage there and replace the hoses AFTER you know they are absolutely not leaking. The hose/pipe connection has a nasty habit of seeping and running along the bottom of the pipe and then dripping off the core on the inside of the case. Fools the best of us. Never tear anything apart until you are SURE what's wrong. Good Luck, Ray Ray Jones, Mena, AR in the Ouachita Mountains in western Arkansas Y'all com'on down and we'll sit ona porch and sip a few.
