Michigan Authorities Warn: See an Open Hydrant, Don’t Do Laundry

'Tis the season for free tire cleaning in Michigan, otherwise known as fire hydrant flushing season. If you're new here and you see a city or township truck parked next to a gushing fire hydrant and you thought, "Why are they doing that?", there's a good reason.

No, hydrant flushing isn't just a reason to see if hydrants are working; it's actually one of the more essential maintenance routines for city water systems. September typically heralds the arrival of fire hydrant flushing season, with many continuing the process through mid-to-late October.

Jackson, Michigan's crews started their flushing process on September 22, 2025, with water flowing into the streets through October 7. East Lansing won't start their maintenance until October 6.

I know, other than avoiding the high-pressure tire wash, why should you care? Well, your laundry certainly does, especially if you prefer clothes without noticeable iron stains. You see, over time, minerals like iron and other sediment settle into Michigan's water pipes.

Turning fire hydrants on full blast clears that gunk out, keeps the water system fresh, and helps maintain good pressure for—you know—important things like firefighting, showers, and your morning coffee.

While the water in your home or business may appear a bit "tinted" during this time, officials say it is still safe to drink, but, and this is a major "but," you'll want to hold off on doing your laundry—unless "rust chic" is the look you're going for.

So, the next time you see hydrants spewing water in Michigan, just know: it's not personal, it's not an inside deal to mess up your laundry schedule or sell Iron Out. Your city isn't trying to stain your socks. They're just making sure your water is as clean and your morning shower isn't a gentle trickle.
