Seeing that reminds of a ice machine we were installing. The plumber showed up the next day while we weren't there and hooked the water lines to the freon line connections. Then his next fatal mistake, he turned the water on and left it on. Went back to finish the install, and discovered the oops. At least it pressure tested okay before he ruined it.
