Cartridge Cylinder Leak Through Top

JB Weld worked great! Thanks for the tip! There were actually a few micro-leaks, so I've gotta repeat the process, but so far so good. Still perplexed how these leaks occurred in a solid piece of thick plastic. Anyone else ever have this happen?

I can only guess. Sounds like either too much pressure or some acid got in there. Epoxy Putty and JB Weld have been long-time friends of mine! I once replaced a heater core in a car, only to nick the new one putting in a better radio. Rather than replace the new one (changing ANYTHING in a 1981 Chevy Citation was hellish experience--my mechanic had nightmares about the carburetor!), I used some epoxy ribbon putty, and never had another problem...with the heater core, that is. I was ecstatic the day I traded that car in on a 4x4 pickup truck!

UPDATE: Drip leaks continued into this season. Practically had entire inside and outside covered in JB Weld, but drips still bled through (Sill perplexed how this happened - you can't even see a hole but drops escape. I guess the pressure did it.) I found a replacement lid for $30 by Hydromatic - identical to my Black Diamond. Working great again. Still interested in why this may have happened so I can prevent a recurrence. Thanks!
