Input: These people are the best.  I don't know anything about plumbing, and I had an unusual plumbing problem at work that had to be fixed asap.  The guy was able to come up with a solution, and actually assembled the parts for me, so all I had to do at work was screw the whole assembly onto the pipe.  Then he didn't even charge me for the adhesives or for his time.  It was amazing.  I'm definitely going back if I have any plumbing trouble in the future.
