Sunday, I finally took the time to switch the lines to the way they should be, with hot on the left. After I was done, I turned on the cold water only to get, well, nothnig. Next I turned on hot, and also got nothing. Well, I actually got a hiss and some sputtering from air stuck in the lines. What I couldn't figure out was why no water would come, even after leaving the faucets open for a minute or two.
Thinking I had some weird clogs in the valves, and that I'd need to unsolder the copper pipes and valves in my shower assembly in order to find and fix the problem, I moved on to other things.
Tonight my son comes down while I'm working on the ceiling, and I show him that his shower's not working. I'm standing their still completely baffled by it all. He on the other hand, looks at it for about two seconds, grabs the shower head, which is a shower-massage head, and switches it out of dribble mode!
You know, I'd have ripped the whole assembly down, unsoldered all the pipes, and probably put the whole mess back together again, and I'd still not have seen the problem.
