So today I completed most of the plumbing...though I say completed with a little hesitation. In the overflow, I couldn't get the PVC to thread completely into the bulkhead so I attempted to add silicone to ensure a "no-leak" fit. Gotta wait until the silicon dries before I test it for leaks. God help me if there are leaks because I can't get my hand in the overflow to re-silicone.
Otherwise, I think everything else went well. I plan to leak-test tomorrow and if all is well, add my SW.
