Spring Sprinkler System Start Up: 5 Irrigation Tips for WI and MN Homeowners


If you live in Wisconsin or Minnesota, you know how to celebrate spring.

Hide your winter boots. Dust off the grill. Run out into the front yard barefoot and reunite with that wonderful green stuff called your lawn.

And spring means it’s time to activate your irrigation system again, woohoo!

When to start up your sprinkler system in spring? That happens between mid-April and the end of May, depending on the weather.

But before you turn on your sprinkler system after winter, you need to really take a look at it.

Winter is long here in Wisconsin and Minnesota, and all irrigation systems need attention.

Approximately 80 percent of them need at least a minor repair after winter.

How to de-winterize your irrigation system?

Put away those mittens and let’s take a look.

1. Inspect Your Sprinkler Heads

Physically inspect every single sprinkler head. There’s a lot that can go wrong:

  • Frost can cause the ground to heave and nudge your sprinkler heads out of whack. That means they might spray your driveway instead of your lawn.
  • The ground probably settled a bit over the winter months. Are the heads sitting high enough so they’re not spraying things they shouldn’t? Adjustments might be needed.
  • Heads could be leaking.
  • A snowplow might have caused damage.
  • Residue in the line can flow to the heads once the water is turned on, clogging the head without you even realizing it.
  • A fitting might have come loose.

2. Adjust Your Irrigation Controller

Before you turn on your irrigation system for spring, you’ll need to reprogram all the settings — what time of day it should run and for how long.

A lot of people unplug their irrigation controller for the winter and it loses all its settings. Now it’s time to de-winterize your irrigation system, and adjusting your controller is key.

Adjust the controller with the seasons.

3. Check Your Rain Sensor

If you have a rain sensor, make sure the batteries are still working and that it’s clear and not obstructed by debris.

4. Test Every Irrigation Zone

Before you start up your sprinkler system in spring, make sure each of your zones turn on and off and run properly.

  • Lightning may have zapped your system.
  • There may be a leak.
  • An animal might have chewed through the pipe.
  • Maybe a zone won’t shut off.

Any of these issues, or others, could be causing your system to waste water and cost you money.
