After bonding, bonding and more bonding, I decided to go ahead and start plumbing the setup. I went ahead and started with the pump to tank plumbing, which went well. I then started on the return lines. I'm about 80% finished. I decided that I wanted to use flexible pipe for the returns, so I halted work until I get to the hardware store today. I hope to have the good 55G and the repaired 55G ready for test fill tonight.
As you can see in the second pic, I learned my lesson with the ball valves. It is worth the extra money to buy the threaded version and just put adapters on them. That way, you can reuse them. When I get to the central tank 're-plumb" job, I will lose about $80 worth of ball valves. I will most likely have to replace every one of them.
