We did a manual dry in a parking garage a few years ago, I asked this
question to the local AHJ and he did require one. NFPA 14 (2013) - 6.4.2
requires one.

This is a Manual Dry Standpipe with one 2-1/2 hose valve on a dock. I do
not see a purpose for the check valve persoanlly.

That is very interesting. I wonder what is the reason one is required?

My only thought is when the fire department disconnects their hoses the
water can come back through the FDC - some people may still install single
clapper FDC's not thinking ahead or the clappers could stick or malfunction
as well.
Greg - in your case I could understand not needing one, other
While back feeding is true they wouldn't take the hose off until they bled down
the hose. Each connection off a fire truck has a bleed valve. With no check
they'll just need to bleed the hose and volume of the standpipe. I don't see
the big deal either way. I didn't read the Code though so
David Sornsin wrote me after my week in the ICU Feb'12 that he assumed all the
nurses were now sprinkler advocates and I was laying in bed in my convention
uniform of khakis, blue button down and blazer.
So Cathy brought the shirt and blazer for me to wear home, and Cecil got some
pics we sent
Bet the FF get soaked since they expect that check is in place like every other
fdc they've seen.
I did a manual dry in mid80s buried in interior pilasters, protected by heat,
and put supervisory water in it for supervision, so needed the check.

In this case, the local FD would be familiar with the SP - it is also
visible and free standing. I know we did one other similar dock without the
check valve in the same county.
Thanks,

I was not able to email yesterday afternoon when this thread started, so
I'm a little late to the conversation. Yes it's required, but has been
since I came onto the committee, so I don't know what the basis for the
requirement was at the time. Obviously, it will keep water in the
system after
Another thought that you triggered with the term free standing: FDC's
can be composed of single clapper and multi-clapper Siamese bodies, or
built out of manifolds with separate snoots for each inlet, including
snoots with spring checks built into them. So the configuration of the
inlet
Wow, is this the second time in your illustrious career that you were not
correct? LOL
Maybe it's time to switch over to fire alarm systems, like me. I still can't
believe I have been on the sprinkler side for so long and never had such an
opportunity to teach at UMD like this. The

Sheesh George! Shaddup! We have all benefited greatly by knowing an old
school 'Automatic Guy' from back in the day. Thanks for sharing all of your
insight and experience with us.
And please tell your wife that we think she is incredible for putting up with
you (and the rest of us)!
I agree.
You won't find it in code. This doesn't even rise to gee, maybe I'm not
getting this. Better grab a pencil and diagram it out.

Draining system is one use of outlet at ground floor, usually only a few feet
above FDC level. If you are in a location where water matters, it is even a
recruit academy drill to hook up to lowest outlet and drain to desired
location.
Then with only a few feet of head push against the FDC
I am looking at a job where they plan to store wood chips in piles on the floor
inside a metal building. I have seen something about criteria in the past that
is close to this, but I can't put my finger on it. Anybody know?
