Broken Valves

Broken valves come in all shapes and sizes.  Some failures are due to mechanical impact damage by people and/or vehicles, some are due to freeze damage (water subjected to cold temperatures resulting in ice thereby causing internal tension overload) and some are unknown.













Freeze damage - below:


Leaking valves, see below.




Same valve above, now removed from system:


Another broken valve handle:



Hose station handle missing:


Wall Post Indicator and Structure Damaged.  Note missing wheel.



Inside the structure - opposite side of WPIV



From the other side of the riser, inside:







Dry Valve Trim Valve photos below - investigation showed air leak through the valve, resulting in dry valve trip.




Broken, below:


Trim valve is missing hand-wheel:


Gauge missing from fire pump, valve body damaged:


It happens before it gets installed, too.


Broken handle is replaced, original left in place.


Missing hardware:


In the following series of photos, a damaged diaphragm on a LP Victaulic valve was found.  I was sent to a site to investigate why a fire sprinkler tech could not reset a newly installed dry valve.  I cannot tell you how the failure occurred, I do not know.  I have redacted the riser room image removing the fire sprinkler contractor's logo.







The following photos show a destroyed butterfly valve.  The water supply is via a private lake and a vertical turbine fire pump taking suction from the lake.  Casino.  I will not disclose location.
