Winterization in Holly
What a Holly winter does to a wet system.
A sprinkler line stays full of water all season. Whatever is still inside when the cold settles in turns to ice, swells and splits pipe, fittings and valve bodies. Around here, that water tends to hide in a few predictable places.
The calendar around Holly
NOAA's 1991 to 2020 normals for Linden, Goodrich, White Lake and Milford put the first 32 degree night between October 6 and 14, and the first 28 degree hard freeze between October 19 and 28. The brass backflow device above ground is exposed first. Buried pipe follows as the ground freezes.
Low spots on rolling ground
The township's master plan places it in the hilly zone, on glacial moraine and till. Water runs to the low point of every zone and waits there. Draining alone leaves those pockets full, so we push air through each zone until the heads spit mist instead of water.
Systems fed by a well
Most township homes water from a private well. We close the irrigation supply and blow out from the yard side of it, so air never goes back toward the pump or the pressure tank. If a pump serves only the sprinklers, it gets drained as well.
The breaker on village water
On village water, the pressure vacuum breaker is what keeps lawn water out of the village supply. It sits above ground on a riser and holds water in its body. We drain it and set its valves for winter, so a hard freeze has nothing to split.
What you get
A fall blowout, zone by zone.
Every blowout follows the same order, so the water comes out of every part that can crack and the backflow device is left ready for winter.
- Water shut off
The irrigation shutoff closed and its drain opened, so the supply line empties.
- Air in below the backflow
The compressor connected past the backflow device, never through it.
- Every zone cleared
Each zone blown out through its heads until it goes from water to mist to dry air.
- No zone run dry
Air set for the pipe in the ground, and no zone left blowing once it is clear.
- Backflow device drained
Test cocks opened and ball valves left half open, so no water is trapped inside.
- Controller off
Switched off for the winter, with anything we noticed noted for the spring startup.
Try it
Blow it out, then let winter come.
Run the blowout zone by zone, then drag the season forward. Skip it and see what the frost does to water left in the lines.
Water is sitting in every pipe, the way it is all summer. Blow it out, or skip it, then drag winter in.
In Holly
Booking a Holly blowout.
Our blowout season opens in late September and runs until the ground freezes, usually into November. Text (810) 423-9513 with your address and your water source (village line, well or lake), and we will set a time.
We need to reach the controller, the irrigation shutoff and the backflow device, plus the pump on a lake lot, so tell us where each one is when you book. After the blowout the controller is switched off. Anything we notice along the way, like a cracked head or a weeping valve, we point out so it can be fixed at startup.

Misty’s Irrigation came out to repair and inspect our lawn irrigation system and did a great job. Very knowledgeable, professional, and just great people to work with. It’s always nice being able to support a local Fenton business, especially when they provide this kind of service. Highly recommend!
Misty’s did some repair work at a fair price. Staff was very pleasant, on time and cleaned up well in addition to excellent communication. Will use them in the future for any sprinkler system needs without it a doubt!
Questions
What people ask about winterization in Holly.
If yours is not here, call or text (810) 423-9513.
When should I schedule a sprinkler blowout in Holly?
Book for late September or October. Misty's runs blowouts from late September into November, and here the first frost usually arrives between October 6 and 14. Earlier is safer than later: once the ground starts to freeze, water left in the lines has nowhere to go. Call or text (810) 423-9513.
Can I just open the drains instead of using air?
Some systems have drain valves, but on rolling ground water sits in every dip between them, and pipe that is not perfectly sloped stays partly full. Compressed air pushes it out zone by zone. It is the step that clears the low spots draining misses.
My sprinklers run off the house well. Does the well need anything?
The house well stays on for the house. We only isolate the irrigation side and blow it out, so the pump and pressure tank are not part of it. If you have a separate pump that feeds only the sprinklers, that pump gets drained too, or it can crack like a pipe.
A hard freeze is coming and my blowout is next week. What should I do?
Turn the controller off and close the irrigation shutoff, usually in the basement. Buried pipe holds up to a cold night or two, because the ground stays warmer than the air. The exposed part is the backflow device on its riser. Text us and we will tell you what to do with it until we get there.
Do lake pump systems get winterized the same way?
The lines and zones, yes. The pump and the intake line need their own steps, because the pump body holds water and the intake runs out into the lake. See lake pump irrigation in Holly.
