Spring Sprinkler Start-Up & Maintenance in South Bend, IN
Charging the system slowly, checking every zone for winter damage, adjusting arcs so water lands on grass instead of the driveway, and setting the controller for the season ahead. Turning the water back on is the easy part.

The visit
What a spring start-up includes
The order matters. Opening the main valve quickly on a system that has sat empty all winter is one of the more reliable ways to break it.
- First
Slow charging of the mainline
Empty pipe refilled too fast produces a pressure surge — water hammer — that can crack fittings and blow heads off risers. The main valve is opened gradually so the system fills under control, with air bleeding out ahead of the water.
- Every zone
Zone-by-zone inspection
Each zone is run and watched. We are looking for heads that will not pop up, heads that will not retract, geysers from broken risers, weeping valves and the wet patches that mark a lateral line split by the winter.
- Coverage
Arc and nozzle adjustment
Heads drift out of alignment over a season from mowers, foot traffic and frost heave. Arcs are reset, nozzles checked for clogging and radius adjusted so the water lands on lawn rather than pavement, fences or the neighbour's driveway.
- Programming
Controller set for the season
Start times, run lengths and days set for spring conditions rather than left on last August's schedule. Rain sensors tested, backup battery replaced if the controller has been losing its program.
- Reported
A list of what needs attention
Anything found gets explained with a price before work happens. Some faults need fixing now; others can wait. We tell you which is which rather than bundling everything into one invoice.
Compliance
Annual backflow testing is required in Indiana
This one catches people out, because it is a legal requirement rather than a maintenance recommendation, and it applies whether or not you use the system.
-
Why irrigation systems need it
Lawns carry fertiliser and pesticide residue, so buried irrigation is treated as a high hazard to the public water supply. Indiana code 327 IAC 8-10 directs utilities to require a backflow prevention device on any residence with an irrigation system.
-
Once every twelve months
Backflow prevention devices must be tested at intervals no greater than one year. South Bend Water Works may require more frequent testing where the hazard is more severe.
-
Testing before start-up
Spring is the natural time to have it done, since the test is due before the system is put back into service for the year.
-
By a certified tester
Only testers certified in Indiana may carry out the test, and the report goes to both the utility and the customer. In South Bend, reports are submitted to the Water Works. We can point you to a certified tester and coordinate the timing with your start-up.
-
It applies even to unused systems
Backflow requirements stay in force unless the irrigation system is physically disconnected from the supply. Not watering the lawn this year does not remove the obligation.
-
What we handle
If the assembly itself has failed, cracked over the winter or is leaking at the test cocks, that is a repair — and repairs to backflow assemblies are ordinary work for us.
Winter damage
What the first run of the year usually reveals
-
Water surfacing in the lawn
A split lateral line, and a repair job. Almost always traces back to water left in the system over winter.
-
A zone that will not start
Usually a solenoid or a wire fault rather than the whole system. Frost heave breaks wire splices as readily as it breaks pipe.
-
Weeping or stuck valves
Grit in the diaphragm from a system that was drained rather than blown out, or a valve body cracked by ice.
-
Heads that stay down
Debris in the barrel or a retraction spring that has given up. Often just needs cleaning rather than replacement.
Start-up in spring, blowout in autumn
The two visits work as a pair. A system cleared properly by an autumn blowout starts up in April with nothing to fix, which is the cheapest year a sprinkler system can have. Book both and you never have to remember the dates.

Straight answers
Spring start-up questions we hear most
When should I turn my sprinkler system on in Indiana?
In northern Indiana, sprinkler systems are usually started up in April or early May, once the ground has thawed and the risk of a hard frost has passed. Turning a system on too early risks refreezing water in shallow lines and above-ground backflow assemblies. Lawns rarely need irrigation before May in this climate, so there is little gained by rushing it.
Can I start up my sprinkler system myself?
You can, but the mainline must be filled slowly. Opening the main valve fully on an empty system sends a pressure surge through the pipe, known as water hammer, which cracks fittings and can blow heads off their risers. The other reason to have it done is that a proper start-up is an inspection — winter damage is much cheaper to find in April than to discover in July.
Do I need a backflow test every year?
Yes. Indiana regulation 327 IAC 8-10 requires backflow prevention devices on irrigation systems to be tested at intervals no greater than one year, and the test must be performed by an Indiana-certified tester with the report submitted to the water utility. The requirement applies even if you did not use the system that year, and it stays in force unless the system is physically disconnected from the water supply.
Why is water coming up through my lawn after start-up?
Water surfacing in the lawn when a zone runs almost always means a cracked lateral line or a broken fitting below grade, and in spring it is nearly always freeze damage from water left in the system over winter. It does not seal itself and it will keep wasting water until the break is located and repaired.
How often should sprinkler heads be adjusted?
Arcs and nozzles are worth checking once a year at start-up. Heads drift out of alignment from mowing, foot traffic, vehicles and frost heave, and a head watering a driveway wastes money twice — on the water itself and on the patch of grass that is no longer being covered.
Should I book start-up and winterization together?
It is the simplest way to keep a system healthy. A properly blown-out system usually starts up with nothing to repair, and booking both at once means neither date gets forgotten — missing the autumn blowout is what generates most of the following spring's repair calls.
