Uh oh -
Either thru overtightening and/or degradation to the fiberglas -- the housing around the drain plug has small cracks in it and I cannot get a seal (replaced the drain plug/Oring).
If I'm screwed and need to get a new housing (5 years old - 4 paper cylinders) should I switch to more efficient, easier to clean an service unit? What would that be? I don't think there is a bondo solution for this? Threads are still good.
A new unit of this type is ~ 800 bucks.
