On Standpipes

The following section contains photographs of standpipe systems.  Hose valves are discussed elsewhere.

In the photo below the hose valve appears to be missing from the standpipe:

The next photo may show a Class 1 standpipe with a missing handle on the hose valve and the standpipe obstructed by miscellaneous storage:

The next photo may show a Class 1 standpipe, the handle on the hose valve may be missing:

The following two (2) photos show an incorrectly installed riser floor clamp and a correctly installed riser floor clamp on a Class 1 Standpipe.  The first photo shows an incorrect installation:

The next photo shows a correct installation of a Class 1 standpipe riser clamp:

Below, a standpipe hose valve is shown with a tie-wrap, is this approved?  Also, the handle appears to be installed backwards.

The next two (2) photos show a pressure reducing valve on standpipe with a potential missing part.


The next photo shows a "model" photo of the pressure reducing valve from the manufacturer.  An arrow points to the part absent from the two (2) previous photos:

Below a small diameter standpipe system is shown with an unusual connection requirement.  Is the responding fire department equipped to connect to this small diameter connection:
A close up:

The photo below may show a Class 1 standpipe with a pressure reducing valve.  The handle appears to be missing:

A close up is below.  Note the setting on this valve:
The following two (2) photos may show a failed support for a manual standpipe system:


The following two (2) photos may show a fractured mechanical support for a standpipe system:



The following photo shows an installation where the installation may partially obstruct the means of egress:


The following photo may show a standpipe with a damaged hose valve handle:


The following photo may show a Class 1 standpipe, the hose valve may have a handle missing.  A gauge set may be missing.



The following series of photos will show a Class 1 Standpipe where unistrut support is detached from structure.  This is a possible design/install error:





Below is another standpipe hose valve that has been tie-wrapped and the handle has been reversed:



The photo below may show another floor riser clamp incorrectly installed:


The following photo may show a Class 1 Standpipe with non-axial loaded all threaded rod supports:


Below a photo may show a hose valve on Class 1 standpipe with a chain/lock installed.  Chain locks on hose valves is not a NFPA requirement.  Does the FD have a key?
