Today’s image comes from one of the loading docks at the Pacific Mill in Lawrence.  I found several of these things around the complex, but have no idea what they do.  Or did.   Well whatever it was supposed to do, I’m pretty sure it’s not doing it anymore.

    Yeah, that’s a pretty cool find, regardless of what it did!

    It looks like a fire hydrant. It makes for a great subject though.

    I agree with Edith, sort of looks like an old-timey hydrant. I guess the sign gave a status of the valve. In any case, it’s a lovely find. Love the way you composed this with the open doorways in the background.

    I love old things like this, what fabulous details and textures! Not to mention the intrigue from the whole “what IS that?” aspect of it!

    That’s a Post Indicating Valve or PIV in the jargon of industrial fire protection systems. The fire protection system water piping is routed underground and these PIVs allow workers to operate the valves from convenient locations above ground. It also allows them to see at a glance the status of the valve.
    Nice photo by the way.

      Thanks so much for solving the mystery of the PIVs. Much appreciated!
