Serving Tiffin
A Tiffin sprinkler company that answers the phone
Tiffin is a growing town west of Coralville along I-80 and Highway 6, with many newer subdivisions.
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 Tiffin yard, the crew that shows up is ours, not a subcontractor.
Tiffin's newer lots are usually open with young trees, which makes them a good fit for full-coverage rotor zones and a Wi-Fi controller from day one.

What we fix on Tiffin 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 Tiffin 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 Tiffin
How a new Tiffin 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%.

What Tiffin homeowners ask us
Why do parts of my lawn stay dry even with sprinklers?
Usually it's head spacing, low pressure or a broken head. We check all three and fix the cause.
How many zones will I need?
It depends on your yard size and the water pressure at your spigot. We measure both on the first visit.
How long does installation take?
Most yards take one day. Larger properties can take two.
Do you offer free estimates?
Yes. Every estimate is free and in writing.
