Serving Iowa City
A Iowa City sprinkler company that answers the phone
Iowa City is the Johnson County seat and home of the University of Iowa. It is one of our busiest areas outside Linn County.
DDM Irrigation has repaired and installed in-ground sprinkler systems across eastern Iowa since 1987. It's the same family business that brothers Dan and Dave started, working out of one shop in Marion. When you call about a Iowa City yard, the crew that shows up is ours, not a subcontractor.
Iowa City work runs from older neighborhoods near downtown with tight side yards to new subdivisions on the east and west sides, plus rental and commercial properties around the university.

What we fix on Iowa City sprinkler systems
Most repair calls start with one symptom: a zone that won't run, a wet spot that won't dry out, or a water bill that jumped. We find the cause, tell you what it costs, and fix it.
- Broken or stuck heads
- Mower strikes, snowplow damage, and heads that won't pop up. We carry common Hunter heads on the truck, so most Iowa City head repairs are done on the first visit.
- Zones that won't turn on or off
- Usually a valve diaphragm, a solenoid, or a cut wire. We trace it with a meter instead of guessing and digging.
- Leaks and wet spots
- A soggy patch or a jump in the water bill usually means a cracked lateral line or a leaking valve. We find it and fix just that section.
- Dry spots and poor coverage
- We re-aim, re-nozzle, or add heads so the whole yard gets water, not the driveway.
- Controller problems
- Old timers that lose their program, or a swap to a Hunter Wi-Fi controller you run from your phone.
- Backflow repair and testing
- 6 of our crew are certified backflow testers. If a device fails, we rebuild it and re-test it.
Sprinkler system installation in Iowa City
How a new Iowa City system goes in
We design every system zone by zone for the yard in front of us. Most residential installs are finished in one day, and every one carries our 1-year warranty.
- 01
On-site walk-through
We come out, measure the yard, note the pressure at your spigot, and determine how many zones your yard requires before we quote a number. Free.
- 02
Zone-by-zone design
Head spacing is planned for full coverage, no dry corners. Drip zones for beds can be added as an extra, priced separately from the lawn zones.
- 03
Trenching & pipe
Trenches are cut with a vibratory plow so the sod goes back down clean, with wire pulled to every valve.
- 04
Controller & valves
Hunter controller wired inside the garage or on the outside of your home, valves buried in boxes flush with the ground.
- 05
Same-day finish
Most residential yards are installed, plumbed, wired, tested, and cleaned up in a single day. We walk you through the controller before we leave.
- 06
First year covered
The first winterization in October and first spring start-up in April are included with the install under the 1-year warranty. Product warranty varies by item.

A sprinkler head broke and DDM scheduled fast and arrived right on time. Dave diagnosed it quickly, explained the repair, replaced the head, then checked the rest of the system before leaving.

DDM has maintained our system for eleven years. They send reminders in spring and fall, give a two-hour window, and show up prompt and friendly every time. I recommend them 100%.
