I work for a water system, and I love fire hydrants, obsessed really. My brother bought an old fire hydrant for me for my birthday and I decided right away it needed to be a fountain/sprinkler. It seemed like it would be simple, since fire hydrant repair and installations are part of my job, but it was trickier than I thought. The first issue I ran into was how small the cavity inside the fire hydrant is, it really limits the plumbing material options and it’s really lucky I have small hands. Luckily the local home improvement store carries a wide variety of flexible water tubing for connecting the internal plumbing, which I found on my third or fourth trip. =) The second issue was finding something that could cut through 4+ inches of cast-iron metal. My tool box is limited when it came to fixing this problem, but luckily some metal working friends allowed me to use their drill press with a 1” bit on it. Perfect for drilling holes through the two side port caps, the top of the hydrant had a hole left after I removed the valve stem. The best surprise was how nicely the popup head sprinklers fit into the holes, almost completely flush so they’re not noticeable when the water isn't running. I also love that I connected it to the sprinkler system so that it runs on a frequent basis and provides more than enough water to our small herb garden. People love it! It’s quirky, fun, and functional. All of the water and fire guys wish they had one, and I love showing it off. The best lesson I learned is when you have the right tool for the right job anything is possible.
