Valve accessibility
Valve accessibility
(OP)
OK, I have been looking to NFPA 13 for the maximum height to mount an test and control valve. NFPA 13 give this example A.8.16.2.5.2.1 An example of an accessible location would be a valve located approximately 7 ft (2.1 m) above the floor level
to which a hose could be connected to discharge the water in
an acceptable manner. So I reckon that any valve test or control can be 7 ft above the finished floor? 7 feet = accessible

There are very loose interpretations across our great nation..

Thanks a lot I recall that but I can not find it, do you happen to have a reference?

RE: Valve accessibility
Sorry. Only reference is in my head and not on paper.
I think this was accepted best practice.
Not sure is it ever was written down.
I think the 7'-0" is based on average height, and our human ability to reach up, to be honest.
Unfortunately, I have had to work on Dry Valves, mounted, you guessed it, 7'-0" above the floor. A lot of them..
The problem is now days, folks are arguing, using ladder means accessible.
Maybe someone can chime in if there is more literature.

This may be enough to get you to the 7' elevation.

It would be easy to supervise.
As to the 7-0 value, the IBC requires any means of egress component to have a clearance of 7'-6" or greater.

RE: Valve accessibility
So as to have it clear in my head..,
As far as egress, I have stuck in my head 7'-6" minimum ceiling height, 6'-8" for components.
I'm sure you know how often this comes up with combination standpipes.
Am I reading those correctly?
RE: Valve accessibility
It's really dependent on where one is in the egress path. I've never believed that in the egress arena that lowering the number is a good thing. Following the most restrictive value solves most problems.
