Spring in Hartland
Why timing matters in Hartland.
Hard freezes are usually done by mid April. Light frosts are not. The NOAA normals for the Milford proving ground station, the closest one to Hartland's ZIP code, put the average last spring frost around May 13, with about a 3 in 10 chance of one coming later than that.
A May frost can catch the backflow device
Once the system is charged, the pressure vacuum breaker by the house is full of water and sitting above ground. A hard frost night in May can crack it. If one is forecast right after your startup, close the irrigation supply for the night, or text us and ask what to do.
Well systems: let the water run clear
EGLE notes iron is common in Michigan groundwater. After a winter of sitting, the first water through a well system can carry rust and sediment. We flush it through before setting heads, and check the filter screens and nozzles for orange buildup that would break up the spray.
Lake pumps wait for the lake
A lake pump cannot start until the ice is gone and the intake sits in open water. Hartland has lake homes on Long, Handy, Round, Maxfield and Dunham Lakes, among others. On those, we check the intake and suction line, prime the pump, and watch the pressure before any zone runs.
Township water: watch for notices
In June 2024 the township asked everyone on its water system to stop watering lawns until July 1 while a well was down for maintenance. A controller with a rain delay or a pause setting makes a request like that easy to follow. We show you where yours is when we set the spring schedule.

What you get
A spring startup, in order.
Every startup follows the same order, so the system fills without a jolt and anything the winter broke is found on the first day, not in July.
- Backflow device opened right
Test cocks and drains closed, ball valves opened slowly, the device checked for freeze cracks.
- Water on slowly
The main line filled a little at a time, with the air let out through the heads.
- Every zone run
Each zone run and walked, not just switched on at the controller.
- Heads adjusted
Clogged nozzles cleaned, sunk heads raised, tilted heads straightened and aimed.
- Leaks found
Wet spots, weak zones and split fittings found and explained before any repair.
- Controller set
Date and time set, backup battery checked, and a spring run time for each zone.

Blowout season.
Get the water out before the ground freezes. A missed blowout shows up in spring as cracked pipes and a split backflow device.

How a Hartland startup goes.
We open the supply slowly so trapped air bleeds out without slamming the heads and fittings. Then every zone runs while we walk it: heads popping up and turning, aimed at grass and not the siding, and no wet spots or dry gaps between them.
Anything that broke over the winter gets found now, not in July. We tell you what it is before we fix it. Then the controller is set for spring watering, not left on last fall's program. Book by text or call at (810) 423-9513, or through the booking form.

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!
Quick to respond to phone message. Scheduled service call and took great care of my sprinkler system, replacing 2 sprinkler heads and checked all of the others. I highly recommended this company for their services
Questions
What people ask about spring startup in Hartland.
If yours is not here, call or text (810) 423-9513.
When should I book my spring sprinkler startup in Hartland?
Misty's Irrigation does startups from about mid April through May, once hard freezes are over. Text or call (810) 423-9513 in March or early April to get a day. If you water from a lake pump, the lake has to be clear of ice first.
Can I turn the system on myself?
You can, if you open the supply valve slowly and walk every zone afterward. The catch is that whatever broke over winter, a cracked head, a split fitting, a backflow device that froze, shows up the moment water hits it, and opening the valve fast can break more. If something sprays where it should not, shut it off and text us a photo.
How much should I water in spring?
Less than most people think. A lawn needs about an inch a week in summer, rain included, and spring rain often covers much of that. On the well drained, gravelly soils of Hartland's hills, water drains through fast, so shorter runs more often work better than one long soak. In the lower, wetter ground, hold off until the lawn shows it needs water. The watering guide has more.
Do you check the well or the lake pump at startup?
We check the parts that feed the sprinklers. On a lake pump, that means the intake, the suction line, priming and pressure. On a well, we watch pressure and flow while the zones run, so a zone that asks for more than the well can give gets spotted. The well itself, the pump down in it and the pressure tank, are a job for a well contractor.
