Well the leak test was going well until I noticed the tiniest of leaks just above my gate valve. When I tried to tighten it up I twisted the bulkhead and made things much worse.
Sump filled great. Holds all the back flow of water from the display tank plus the overflow is drained as well.
Display tank with empty overflow due to leaking bulkhead.
Damn bulkhead leak. I can't access it at the moment without draining the tank. I don't know if I should drain the tank or try and cut a bigger hole on the bottom of the stand so I can access the nut without draining.
PITA either way I guess.
