Short Answer: For most Tulsa-area irrigation systems, repair is the right call. Systems under 15 years old with isolated problems (a broken head, a leaky valve, a blown zone) are usually worth repairing for $150 to $800 per repair visit. Replacement makes more sense when you have a system older than 20 years with repeated failures, original materials that are failing throughout, poor original design that never delivered proper coverage, or when you are adding significant landscape changes that require new zones anyway. A full residential replacement runs $3,500 to $10,000+ depending on property size and system complexity. Here is how to know which path fits your situation.
Your irrigation system is supposed to be the kind of thing you do not think about. You set the controller in spring, it runs through summer, you turn it off in fall, and you enjoy a green yard without dragging hoses around.
Except when it stops working. Then suddenly you are wondering whether the $400 estimate you just got for repair number seven this year is really solving the problem, or whether you are pouring money into a system that is just going to keep failing.
That is the repair versus replace question, and it is genuinely tricky. Here is how we walk through it with homeowners.
The Core Question: How Old Is the System
Age is the biggest factor in the decision. Rough guidance:
Under 10 years old. Almost always repair. Modern systems in this age range are usually working as designed, and isolated failures are normal maintenance items rather than end-of-life signals.
10 to 15 years old. Usually repair, but pay attention to patterns. If you are doing 3 or 4 repair visits per year on the same system, you may be approaching the replacement conversation.
15 to 20 years old. Gray zone. Individual repairs still make sense, but start thinking seriously about whether the next big repair (main line, valve manifold, controller) should trigger replacement instead.
Over 20 years old. Replacement conversation. Systems this age are past their design life and usually have multiple failing components. The repair money often funds a system that fails in another place next season.
This is not a strict rule. Some well-installed systems last 25+ years. Some poorly installed systems start failing at 10. Age is the starting point, not the final answer.
Signs You Should Repair
Clear indicators that repair is the right path:
Isolated failures. A broken head, a leaking valve, a single non-working zone, a controller that died. These are all routine repair items, even on older systems.
Recent installation. Systems under 10 years old have a lot of useful life remaining. Repair is almost always better than replacement.
Good original design. If the system was properly designed and installed (appropriate head spacing, good pressure management, well-sized zones), the bones are good and repair preserves that design.
Coverage still works. If your lawn is green and the system delivers water where it needs to go, the design is working. Fix the mechanical issues without starting over.
Budget constraints. Even a borderline system is usually worth keeping alive with repairs if the replacement budget is not available. A $600 repair today is cheaper than $6,000 replacement.
Signs You Should Consider Replacement
Clear indicators that pushing further on repairs stops making financial sense:
Repeated failures in different places. A system that had one issue this month, a different issue last month, and another issue two months before that is telling you something. Repairing the latest symptom does not address the underlying decline.
Original materials are failing throughout. If you keep finding the same age-related failure (gaskets cracking, poly fittings splitting, specific valve models failing), you will keep finding them until the material is replaced systemically.
Coverage was never right. Some systems were poorly designed from installation. Dry patches, overspray onto driveways, overlap that floods some areas while starving others. Repair cannot fix design. Replacement gives you the chance to do it right.
Pressure problems throughout. If the entire system has pressure issues that are not solved by individual repairs, the main line, sizing, or source water configuration is wrong. Addressing this typically means substantial rework that is close to full replacement anyway.
Major landscape changes. Adding beds, moving hardscape, expanding the lawn, or renovating significantly often means the original zones no longer match the property. Redesign and replacement is often cheaper than extensive modification.
Old controller with no smart features. Older mechanical controllers without weather integration, smart scheduling, or zone-level programming are a meaningful water and money waste. Replacing with modern smart controllers alone is often worthwhile, though this is usually part of a repair project rather than full replacement.
The Gray Zone: When Repair and Replace Both Make Sense
Plenty of systems sit in the middle. Here are the considerations that tip it one way or the other:
Remaining useful life of repaired components. If the repair is replacing a valve, that new valve might last 15+ years, which extends the useful life of the whole system meaningfully. If the repair is a temporary patch on a cracked poly line that will fail again, the money is more questionable.
Total repair costs as a percentage of replacement. When accumulated repair costs over a 2 to 3 year period approach 30 to 40 percent of replacement cost, replacement starts looking better.
Water waste costs. Old inefficient systems waste water continuously through poor coverage, overspray, or stuck valves. Modern systems often save 20 to 40 percent on water bills. Those savings compound and partially fund the replacement.
Property plans. If you plan to sell in 2 years, keeping the current system alive with minimal repair makes sense. If you plan to stay 10+ years, replacement often pays back.
Disruption tolerance. Replacement is disruptive. Trenches across the lawn, heads relocated, everything is off for a few days. Some homeowners would rather do repeated repairs than accept a major installation project.
What Repair Typically Costs
Rough ranges for common repair items in the Tulsa area:
Broken head replacement: $25 to $60 per head including labor.
Valve replacement: $150 to $300 per valve.
Lateral line repair: $150 to $400 depending on depth and access.
Main line repair: $300 to $800+ depending on location and complexity.
Controller replacement: $200 to $600 for standard, higher for smart controllers with installation.
Backflow preventer repair or replacement: $150 to $500.
System diagnostic (including leak detection): $100 to $300 as a service call if no repair is done.
Most repair visits cost $150 to $800 total depending on what is found and fixed. Service call fees typically run $75 to $125.
What Replacement Typically Costs
Replacement is a bigger project. Ballpark ranges for Tulsa-area residential replacement:
Small residential properties (under 5,000 square feet of coverage): $3,500 to $6,000.
Standard residential properties (5,000 to 10,000 square feet): $5,500 to $9,000.
Larger residential properties (10,000 to 20,000 square feet): $8,000 to $15,000+.
Very large properties or complex designs: Custom pricing, often $15,000 to $30,000+.
These ranges include design, materials, installation labor, smart controller, permits (where required), backflow preventer, and initial startup and calibration. Trench repair (where the trenches were dug) is typically included but may be basic (lawn recovery) rather than pristine restoration.
What Modern Systems Get You
If you are weighing replacement, understand what modern systems offer that older ones do not:
Smart controllers. Weather-based scheduling that skips watering after rain, adjusts based on temperature and humidity, and works from your phone. Water savings alone often justify this feature.
Pressure-regulated heads. Modern heads maintain consistent output across pressure variations. This improves uniformity and reduces waste.
Matched precipitation rate heads. Different head types (spray versus rotor) now come with matched precipitation rates, which allow mixing head types in the same zone without causing over or under-watering.
Drip irrigation for beds. Modern systems integrate drip for landscape beds, which is far more efficient than overhead spray for plants that are not lawn.
Better valve reliability. Current valve designs are more robust than valves from 20+ years ago.
Flow sensors. Some modern systems include flow sensors that detect breaks automatically and shut down affected zones, preventing major water loss events.
Zone additions and changes are easier. Modern controllers typically have more zones and better programming flexibility for future modifications.
How to Get a Real Answer for Your System
A proper evaluation of your specific system should include:
Full system test. Each zone run through a cycle, coverage evaluated, pressure checked at various points. Often reveals issues the homeowner did not notice.
Component inspection. Valve condition, controller state, backflow preventer status, visible main line condition where accessible.
Design assessment. Is head placement appropriate? Is zoning correct for current landscape? Are pressure and flow in good ranges?
Repair history review. How many service calls in the last 2 to 3 years? What was done each time?
Water bill review. Is the system using appropriate water volumes for the property and climate? Consistent high bills may indicate leaks or inefficient operation.
At the end of that evaluation, a good company can tell you honestly whether repairs are solving the right problem or whether replacement makes more sense. Some systems that look bad are actually fine with targeted repairs. Some systems that look fine are actually on the edge of multiple failures and replacement makes sense sooner rather than later.
