bulkheads and diameters and stuffs

[sphelps]

I've repaired quite a few tanks with damaged bulkheads. Sometimes cracked, cross threaded or just leaking. Never seen any problems with the good sch80s, Sch40s are good to but those cheap sch20 black ones are complete junk. Threads are too fine, not reverse threaded, think brittle plastic, and tiny thin gaskets. You're just asking for trouble using those and they are usually the ones I'm always fixing.

The money you save is peanuts compared to the rest of the setup, if you use cheap bulkheads might as well use thinner glass to and skip the home insurance. Especially on a close loop where replacing a bulkhead means draining the tank.
