Leaks

Lots and lots of leaks out there. This leak is on a 3% AFFF foam system at a military aviation repair facility.


Below we have a leak in a busy fire pump room, note yellow arrow.






Evidence of small leak on 3% AFFF foam bladder tank.  Leak may have occurred during ITM operations at flange by flange gasket.




Leaks during a fire pump test.

Another possible leak on this above ground heat traced supply is shown below:

Below, a number of leaks are found (not photographed).  Photo shows marking of pipe for later service:

Another photo of the same system possibly showing a leak:

Photo below shows an additional section of this pipe network with possible leak.  Cannot be ascertained due to  lack of ground clearance:

Below, an OS&Y control valve is shown with no apparent signage.  Also shown is an old leak on the backside of a Multimatic A-4 deluge valve (trimmed as a DIPA).  Note the "napkin" in the photo.
