Re: Automatic flushers

[Bernard Cleyet <anngeorg@PACBELL.NET>]

And why didn't the facilities person (pc) give you a broken one (or new spare)
to "play with?"

How about going to an exterior decorator contractor for a broken sprinkler
valve.

One may (with tax deduction) go to the local independent (pc) hdw. store and
purchase a sprinkler valve (they might even give you one after stressing the
need to teach young physicists to help fight the war against terrorism.  You
could, if he refuses, be very manipulative and say you'd blame him for the
failure of the war.)

OK enuff politics.  If all else fails, I'll make a project out of this and get
one (the real thing, not a sprinkler valve [I think I have a broken sprinkler
one I replaced]) take photo's and send them if I get enuff applicants (off
list)  I hope it doesn't break my bank.
