I know to some folks they are junk but to some they are treasure. I'm in between.
I've seen them laying where they were broken off by a car and wondered if broken they would be given away. I stopped and asked once but was told I'd have to call their office. I didn't bother. That's been years ago. Then I found these. I fully expect that after painting the second one I'll get over a $100 for it on Craig's list. Like most folks I expect, mine will be a lawn ornament. I have an old gas pump I need to paint too and I plan to put them outside a metal building I have. I guess if you have a game room or man cave or shop that you decorate you could use it there. Or if you are a fireman you might have a lot of fire collectables and love a old hydrant in the corner of your living room. Two could be used as legs with a glass top for a unique table. Dog owners, men and women, like them to give dogs something to pee on but I doubt the dogs really care. It would be a great ornament outside a vet office or dog rescue etc.
If you find another broken one and all the pieces are there perhaps it can be tack welded back together--remember it's just for display. Frankly the jury is still out if I make enough to pay for my time in cleaning the pump and painting it to make it worth my while. Chemical cleaners and wire brushes for the grinder are expensive and spray paint is too. I paid $50 for each and trust me that is much cheaper than I will ever find for a unbroken hydrant with all the caps. Plus these have the fluting on the top that I like.
If I had a can of red paint to brush on I expect I'd get the most bang for the buck not cleaning it and just slopping on some red paint so it'd take a nice picture but I want mine done pretty nice and the one I plan to sell I'd do similarly and try to take pics that show how nicely it's done.
Theft is something to be concerned about if left in the front yard and it's obvious it's ornamental as it would be out in the country where I live and not actually connected. Of course they'd still have to work for it as the smaller of mine weights 150lbs and the larger 220lbs.
