Based upon some solid advice, and a strong dislike for the previous plumbing, I decided to redo the plumbing on the tank/sump.
I wanted to reuse the fancy trigger systems sump that I had purchased for the previous tank:
The previous owner of the tank had taken the unusual step of attaching a 2" union to the outside of the bulkhead. It took me a long time to figure it out and even longer to realize that the union was glued to the bulkhead. This made it impossible to unscrew the bulkhead. I tried replacing half of the union with a new one, only to realize that the threading of schedule 40 unions is not uniform:
Luckily I had picked up an inexpensive handsaw at the local Ace Hardware Store and I went to town on the bulkheads:
Several trips to Home Depot, a specialty plumber store and back to my LFS later, I had new bulkheads on hand. Unfortunately I managed to strip them both by getting sand into the threads.
One of the guys at the LFS felt bad for me and gave me a new as a Christmas present.
New bulkheads installed, I got out the primer/cement and went about finishing out the plumbing. It was a bit odd to use my new saw on my office desk, but ...
At the risk of jinxing myself, I am pretty hspoy with how it turned out:
