Drywall is hung, these pics are after the first coat of mud Sunday night, and I was able to sand and get the second coat of mud on last night....getting there!
So that bulkhead fitting under the right side corner I thought I had taken care of....yeah not so much. It started leaking like a sieve when I hooked up the return pump. I thought I was screwed, since I couldn't get access to the nut to get it tighter OR to take it off. Finally I came up with this little jobby to take care of it. I heated the end of a piece of 2" PVC with a torch to soften it up, then forced it over a spare bulkhead nut, and ran it under cold water until it hardened. I was able to get it locked onto the nut under the tank, get the old bulkhead out, clean the area out, and get a new one in there. No more leaks!
The sump is running on the tank now too, I first hooked up the Quiet One 9000 for a return pump, but ironically, it was super loud. It might need an impeller or something, but in any case, since my koi pond filter is shut down for the winter, I grabbed the Oceanrunner 6500 off that and I'm using that as a return pump. Dead silent running submerged, very happy with it so far.
