This is a new valve that I've had too long to return---it's a PV2 Disc/Drum combination valve that is leaking where indicated in the pic below. I am also including a cross section of the valve for reference. After doing some research, I have found this to be a relatively common problem with these brass valves, but have not found if anyone has been able to repair the leak. Can this successfully be fixed
or am I stuck buying another valve...again???
