I can't understand why PVC cement won't work. Isn't lye a drain cleaner? PVC stuff is made to handle lye. It must be over a long period of time that creates the problem. I'm still using PVC cement, but just incase vibration also causes leaks I think I'll put rubber on the mount.

I've been using PVC cement with my PVC reservoir tubes for many months and it's held up fine, even with max concentration electrolyte.
(EDIT: I think I already said this.... isn't age a *****?)
Those are very good points. My resevoir is what I used to construct my bath cells with before I got into dry cells, so it's had a high concentration e lyte in it for several months. I didn't develop the leak till it had been mounted to the bed of my truck for a couple of weeks.
Fortunately it leaks very little and onto a rubber bed protector, but any leak at all is bad.
Without getting lots of heavy objects thrown at me....
You guys aren't exceeding the 140F limit, are you?
If heat is the problem switch to CPVC and CPVC cement both have working temps of 212 and forming temps in the 350 degree range.
