Bulkheads

[Alberta-newb]

Double check the diameter as well! I just went through an emergency bulkhead change myself. The 1" bulkhead the LFS sold me was a polypropylene type sold at farm supply like UFA and perhaps Peavy Mart?. Anyway, the threaded section for the nut was too big to fit through the hole in the glass! Very frustrating to find this out after draining out my sump into buckets and dismantling all the plumbing. patched it back together and let it drip until i found a proper one this weekend at another store.
