Nonsense. I've used them multiple times without problems.


Do a search on the history in this newsgroup and see how many posts deal
with broke drain valves on water heaters. One of the biggest problems with
valves is non use and they get corroded and cannot turn or will not seal
when closed. While at it, check for the posts about washing machine valves
that don't close too.

I just heard a story this morning about a job gone wrong. A crane and crew
called in to replace some equipment. Crew was told, everything is ready,
you just have to turn the air off. Well, the air valve has not been turned
in years. It was a five hour project getting it turned off.
