You walk the yard of your new potential home during a showing. The grass looks green, the flower beds look tidy, and the listing says, “sprinkler system.” What the listing doesn’t tell you: whether every zone actually runs, whether a cracked line soaks the side yard, or whether a tilted head has sprayed the same brick wall every morning for three summers.
Most buyers find out with their first water bill. A sprinkler inspection in Tulsa gives you those answers before closing, while you still have time to ask questions, request repairs, and make the most informed decision possible.
| Why Tulsa Buyers Add a Sprinkler Inspection |
 Oklahoma’s Standards of Practice for home inspectors specifically excludes lawn sprinkler systems. |
| Most of the system sits underground, where leaks and cracked lines stay out of sight. |
| A leaking system can waste up to 25,000 gallons of water in a single irrigation season. |
| Misdirected spray and hidden leaks can send water toward your home’s foundation. |
| Tulsa requires a backflow preventer on every residential irrigation system. |
At Assured Home Inspectors (AHI), we offer a sprinkler system inspection as an add-on to our home inspections throughout Tulsa, Broken Arrow, Jenks, Bixby, Owasso, and surrounding communities. Here’s what it covers, what we find most often, and how to get the most out of it.

Is a Sprinkler System Included in an Oklahoma Home Inspection?
The Short Answer: No.
Oklahoma’s home inspection rules list “fire and lawn sprinkler systems” among the items a licensed inspector is not required to inspect. Unless you add a sprinkler inspection, assume no one tested the system.
The Oklahoma Construction Industries Board (CIB) licenses home inspectors and sets the Standards of Practice they follow. Under Oklahoma Administrative Code 158:70, a home inspection is a visual examination of the readily accessible parts of a home, including the structure, roof, electrical, plumbing, and HVAC systems. Section 158:70-1-3 specifically excludes lawn sprinkler systems from evaluation.
That surprises a lot of buyers. Your general home inspection covers the home’s major systems, but the sprinkler system can slip through the cracks. That’s exactly why AHI offers a sprinkler inspection as an add-on: so, you can see the system run before you own it.
| General Home Inspection | AHI Sprinkler Inspection Add-On |
| Covers the home’s structure and major systems |
Operates the sprinkler system using its normal controls |
| Lawn sprinkler systems excluded under Oklahoma’s Standards of Practice |
Runs available zones to check coverage and pressure |
| Zones typically stay off during the inspection |
Evaluates heads, the controller, and accessible valves |
| Backflow preventer sits outside the required scope |
Visually checks a visible, accessible backflow preventer |
What AHI Checks During a Sprinkler Inspection
Our inspector identifies the sprinkler components on the property, runs the system using its normal controls, and looks for visible signs that something isn’t working the way it should. Here’s what that covers:
| Sprinkler Inspection: What We Review | |
| What We Review | Why It Matters |
Sprinkler head positioning, pressure, spray pattern, and pop-up function |
Tilted, stuck, or broken heads waste water and miss the landscaping. |
Operation of available zones |
Reveals dead zones, weak pressure, and uneven coverage. |
Controller operation and visible defects |
A faulty controller can skip zones or water at the wrong times. |
Valves, when accessible and visible |
A valve that won’t close fully can let water seep nonstop. |
Backflow preventer, when visible and accessible |
Protects your drinking water; Tulsa requires one on residential systems. |
Visible leaks, pooling, erosion, and abnormal flow |
Often the first visible sign of a broken underground line. |
What a Sprinkler Inspection Can’t Do
We believe in setting honest expectations. A sprinkler inspection is a visual, non-invasive evaluation, so it has limits:
- Buried components stay hidden.
We can’t see the condition of every underground pipe, fitting, or wire. - We don’t dig.
Locating and excavating a concealed leak falls to an irrigation contractor. - It isn’t a backflow test.
We visually evaluate the backflow device; a qualified backflow professional handles testing and certification. - It’s a snapshot.
The report reflects the system’s condition on inspection day. - The system needs to be on.
We can’t turn on systems that are shut off at the valves.
Every sprinkler system needs maintenance or repair at some point. Our job is to show you where yours stands today so you can plan for it.
Common Sprinkler Problems We Find in the Tulsa Area
After more than 12,000 inspections, we see the same irrigation issues repeatedly. Here are the ones that show up most often:
| Common Findings | Severity | Description | Recommended Action |
| Controller Issues | Minor to Moderate | 
Zones that don’t run, run at odd times, or keep running. |
Reprogram, repair, or replace the controller. |
| Broken or Damaged Heads | Minor to Moderate | 
Heads that won’t pop up, leak at the base, or shoot a geyser of water; often caused by mowers, vehicles, or foot traffic. |
Repair or replace the head. |
| Poor Spray Coverage | Minor to Moderate | 
Water hitting the driveway, sidewalk, fence, or house; brown or dry patches nearby. |
Adjust or realign heads toward the landscape. |
| Exposed Sprinkler Pipe | Minor to Moderate | 
Sprinkler lines lying on top of the soil or barely covered, often along the foundation, beds, or worn areas where soil has washed away. |
Have a qualified irrigation contractor rebury the line and repair any damaged sections. |
| Leaks and Flow Problems | Moderate to Severe | 
Soggy or sunken spots, pooling, erosion, weak pressure in one zone, or a strip of unusually lush grass. |
Have a qualified irrigation contractor locate and repair the leak. |
| Backflow Concerns | Moderate to Severe | 
A missing, damaged, or leaking backflow device. |
Contact a licensed plumber or certified backflow tester. |
| Freeze Damage | Moderate to Severe | 
Cracked pipes, split fittings, or leaks. |
Repair damage and winterize the system every fall. |
A Closer Look at Backflow Prevention
A backflow preventer keeps irrigation water, which can carry fertilizer, pesticides, and soil, from flowing back into your home’s drinking water. The City of Tulsa takes this seriously. Title 11-C of Tulsa’s Revised Ordinances states that all residential irrigation systems must have a backflow preventer. Broken Arrow, Bixby, Jenks, Owasso, and other nearby cities set their own requirements, so check with your local water utility.
Oklahoma Winters and Your Sprinkler Lines
Oklahoma regularly sees hard freezes. According to InterNACHI, failing to drain an irrigation system before freezing weather can crack the underground system and compromise the entire setup. A home that sat vacant over winter, or had a seller who skipped winterization, deserves a closer look.

Why Sprinkler Problems Matter When You Buy
Next to the roof, the foundation, or the HVAC system, a sprinkler system can feel like a minor detail. Here’s why it deserves your attention.
Prevent High Water Bills
Tulsa bills water by metered usage, so a leaking system will show up on your bill every month. The EPA’s WaterSense program estimates that a leaking irrigation system can waste up to 25,000 gallons of water and about $280 over a six-month irrigation season. The City of Tulsa also calculates residential sewer charges from water use billed in December, January, and February. So, a leak or runaway controller during those months can push your “sewer cap” higher for the following year.
Protect Your Home and Hardscaping
Heads that repeatedly spray siding, brick, or wood trim, or a leak that saturates the soil along the foundation, can contribute to moisture damage and deterioration over time. InterNACHI recommends keeping sprinkler heads away from foundations, decks, and porches.
Avoid Surprise Repair Costs
One broken head is a quick fix, but several failed zones, a bad controller, or an underground leak can add up fast. Finding these issues during your inspection period gives you time to get repair estimates and negotiate, instead of footing the bill after closing.

Who Should Get a Sprinkler Inspection?
Home Buyers
Add it to your general home inspection to learn about the system before you commit.
Real Estate Investors
Know what you’re taking on before you buy a rental or flip. Tenants often don’t notice or report slow leaks, and the water bill may land on you.
Homeowners
Pair a sprinkler check with an annual maintenance inspection for a full picture of your property’s condition.
Realtors
Help your clients answer a question that often gets missed: “Did anyone actually test the sprinkler system?”
How to Prepare for Your Sprinkler Inspection
A little preparation helps us give you a more complete irrigation system inspection in Tulsa. If you’re the buyer, ask your agent to confirm these items with the seller ahead of time:
Turn the sprinkler system on and confirm it works.
Open the water-supply valves that serve the system.
Make sure we can reach the controller.
Clear access to valve boxes and other known components.
Move vehicles, stored items, or anything blocking sprinkler heads.
Share any known concerns, such as wet areas, high water bills, or zones that act up.
Important:
AHI cannot turn on irrigation systems that are shut off at their valves. A system that’s ready to run allows a far more useful inspection.
What Happens After the Inspection
You receive your report the same day. AHI documents findings with photos in an easy-to-read electronic report.
You talk it through. Call or text your inspector with any questions about what we found.
You build your repair request. AHI reports include access to HomeGauge’s Create Request List™ feature, which helps you and your Realtor organize findings into a repair request.
You decide on next steps. For significant findings, get estimates from a qualified irrigation contractor or licensed plumber before your inspection period ends.
Seasonal Sprinkler Care for Oklahoma Homeowners
Already own your home? These habits, adapted from the EPA WaterSense Sprinkler Spruce-Up guidance, help keep your system efficient year-round:
| Seasonal Sprinkler Care | |
| When | What to Do |
| Spring Startup | Turn the system on slowly, then walk every zone. Look for heads that don’t pop up fully or spray in the wrong direction. |
| Summer | Check connections for leaks and redirect any heads spraying driveways, sidewalks, or walls back toward the landscape. |
| After Mowing or Yard Work | Scan for clipped or crushed heads. |
| Fall | Winterize and drain the system before the first hard freeze. |
| Anytime | Watch your water bill. A sudden spike is often the first clue that something is leaking. |
