We always open the top valve, and plug the closed bottom valve. Without a
wrench this makes an accidental trip almost impossible.
I've seen the advertisement in sprinkler age for the new "Metraflex" "Never
Trip" drum drip replacement. Has anyone tried these yet? How's the cost
compare to a drum drip?

We always close both because with one open and active spring breakers, we
have had tripped systems.

Todd, The fitter was probably telling you the truth, which is that he was
taught to close both valves. When I started in the field in the late 70's,
I
was taught the same thing. This is a good reason to promote the AFSA
apprenticeship program so the fitters coming up now can be taught the
correct way to do things. And yes, according to the apprenticeship course,
the top valve is to be left open. Gregg

Subject: drum drip
When a drum drip is left in 'normal' position, which valves are open
and which closed? I always thought that the top valve is open and the
bottom valve shut. A fitter told me that both valves are supposed to
be shut. When I asked him where that came from, he admitted that's
what he was taught. Which is correct, if either?
