This water pipe, called a Post Indicator Valve, or PIV for short, stands
askew in the grass outside the Music Hall building at the Snug Harbor
Cultural Center on Staten Island.
A PIV is a valve used to control the water supply to fire protection
systems in large buildings. It's the connection and control between
the private and the public water system. One of the things I enjoy doing
with these urban sketches is the subsequent research, either to
discover the history of a particular building, or just what the heck it
is that I drew, like these random water pipes sticking out of the
ground. Very often, I come across some website that tells you more than
you ever wanted of needed to know about the subject at hand. Like
this site,
which not only tells you all you need to know about Post Indicator
Valves, but about fire hydrants in general, and even about the history
of the Kennedy Valve Manufacturing Company, which is still in the
hydrant business in Elmira, NY. So now I not only know what a Post
Indicator Valve is, but that this one is a
P027 Model 541.
