I added a regulator on the spot free rinse today. In the process I broke the main spot free access line? 
So I had to purchase a nipple extractor to remove the broken piece. 
Then I had to remove the piece. 
Then I also had to drive around to try and find a 1″ fitting. Which I wanted plastic and ended up with galvanized. 
I also had to drain the tank which is bad because the membrane in the system needs to be replace. So the process took forever. It was a lot of fun and I got my feet wet.
