Winterizing your sprinkler system is kind of like putting your garden to bed for the season. But even after a proper blowout, winter has a way of testing pipes, fittings, and valves (thanks, freeze-thaw cycles). At Spartan Irrigation, we always tell homeowners: winterization is step one; staying alert is step two. Here are four signs a winter water leak might be creeping in, along with what to do next.
If your irrigation is off but your bill climbs, that’s a big red flag. Leaks can happen at the backflow preventer, shutoff valve, or even a small crack in a line that didn’t fully drain. Try turning off all water inside, then check your water meter. If it’s still moving, you may have a leak. Be sure to give us a call if this is the case!
A soggy patch in the yard when it’s cold and dry outside is suspicious, especially if it’s near valve boxes, sprinkler heads, or along known irrigation lines. If you find one, mark the spot with a small flag or stake. If it grows over a few days (or you notice water pooling during a warmer spell), it’s time for a leak check.
If you’ve got one shiny ice patch that shows up repeatedly—even when everything else looks normal—it could be water rising from below and freezing on the surface. But don’t chip at it (you could damage components underneath). Instead, take a quick photo and note the location so it’s easy to identify once warmer weather hits.
Even winterized systems can have trouble around the shutoff valve or backflow assembly, especially if the insulation shifted or a hard freeze hit at the wrong time. So, peek at the area on a mild day. If you see moisture, dripping, or unusual frost buildup, schedule an inspection.
Winter leaks don’t always announce themselves loudly—but the sooner you catch them, the easier (and cheaper) they are to fix. If you want peace of mind, Spartan Irrigation can help with irrigation system repairs and inspections, winterization, spring sprinkler installation, and even outdoor lighting upgrades—so your yard is ready to shine when warmer weather hits here in Lansing, MI.
