First toilet flush test
Well, after all the hoses and wires were connected the toilet appeared to be dead. As I started troubleshooting, I realized that an inline fuse holder was wired into the +12V wire from the battery but I never actually put a fuse in it! Once that was fixed, we were in business. No leaks, no troubles. Happy!
