We had a funny exchange at the plumbing supply store when I went to get a new fill valve for the bathroom in my office since after replacing our completely broken toilet we noticed this one was perpetually running as well. We picked this up at the same place as we got our toilet, which is for professional contractors, and for a moment I was confused by something he asked that made it seem like we needed to be pros to shop there. I then made a joke about how the box for this valve says "for professional installation only." MrsBlue asked if that was going to be a problem, to which the clerk replied, "not for me." Good stuff. Anyway, installation seemed to go without a hitch, so that keeps up for a couple of days I'll allow everyone to remove their life-jackets.
