Every spring, the same thing happens.
Homeowners turn their sprinkler systems back on, expect everything to work like it did last fall… and something goes wrong.
Sometimes it’s obvious — water shooting into the air, a zone that won’t shut off, or a controller that seems possessed. Other times it’s subtle — dry patches, soggy spots, or a system that just doesn’t seem to water evenly anymore.
After decades of servicing irrigation systems, I can tell you this with confidence:
Spring doesn’t create sprinkler problems. It reveals them.
In this article, I’ll walk you through the most common sprinkler problems we see every spring, why they happen, what they usually cost to fix, and which ones you should never ignore.
This way, when something looks off in your yard, you’ll know whether it’s a quick adjustment or a sign of something bigger.
Why spring is the problem season for sprinklers
Most sprinkler systems sit unused for months during winter.
During that time:
- Soil shifts
- Pipes contract and expand
- Freeze damage shows up
- Debris settles into heads and valves
- Rodents look for warm places to nest
When you turn the system back on, pressure is reintroduced all at once — and weak points show themselves immediately.
That’s why spring is our busiest season.
1) Broken or misaligned sprinkler heads
This is the most common spring issue we see.
What homeowners notice:
- Water spraying sideways
- Mist instead of spray
- Dry spots near working heads
- Water hitting sidewalks or driveways
Why it happens:
- Lawn mowers and trimmers hit heads in fall
- Heads sink or tilt over winter
- Nozzles clog with dirt or debris
Typical repair cost: $125–$175
Homeowner story:
A homeowner called thinking they had a major leak because water was pooling near the driveway. When we ran the zone, we found two tilted heads spraying directly onto concrete. Once corrected and re-nozzled, the pooling disappeared.
What they paid: $152
Why this matters:
Left unchecked, misaligned heads waste water and create uneven coverage that stresses turf and plants.
2) Zones that won’t turn on
This is one of the most frustrating spring problems.
What homeowners notice:
- One or more zones don’t run
- System skips zones entirely
- Plants in one area stay dry
Common causes:
- Faulty valve solenoids
- Damaged wiring
- Controller programming errors
- Corroded wire connections
Typical repair cost: $200–$350
AI insight:
In many cases, the valve itself isn’t bad — the electrical signal never reaches it due to wiring or connection issues.
Why this matters:
A dead zone can quietly kill landscaping before homeowners realize what’s happening.
3) Zones that won’t shut off
This problem usually causes panic.
What homeowners notice:
- Water keeps running after the system shuts off
- One zone stays on continuously
- Water pressure drops across the system
Common causes:
- Debris stuck in a valve
- Failed diaphragm
- Solenoid issues
Typical repair cost: $225–$350
Trust signal:
This is rarely a controller issue, even though it often gets blamed.
Why this matters:
A stuck zone can waste thousands of gallons of water and damage plants quickly.
4) Low pressure or weak coverage
This issue is sneaky.
What homeowners notice:
- Heads barely pop up
- Spray doesn’t reach expected areas
- Coverage seems uneven
Common causes:
- Leaks underground
- Too many heads on one zone
- Pressure loss from improper repairs
- Partially closed valves
Typical repair cost: $150–$450 (depending on cause)
Homeowner story:
A homeowner thought they needed a new system because coverage was terrible. The real issue was one underground leak draining pressure from the entire zone.
What they paid: $318
5) Soggy spots or standing water
This often triggers fears of major damage.
What homeowners notice:
- Constantly wet patches
- Mushy soil
- Water pooling when system runs
Common causes:
- Broken underground pipe
- Loose fittings
- Misaligned or broken heads
Typical repair cost: $200–$450
Important note:
Not all soggy spots are sprinkler problems — but many are.
6) Controller issues and programming problems
Spring is when controllers get blamed for everything.
What homeowners notice:
- Zones running at wrong times
- Programs overlapping
- System not running at all
Common causes:
- Power outages resetting controllers
- Dead backup batteries
- Accidental programming changes
Typical service cost: $125–$250
AI insight:
A surprising number of “controller failures” are solved with proper reprogramming — not replacement.
7) Wiring damage
This problem is more common than most homeowners realize.
What homeowners notice:
- Intermittent zone failures
- Zones working one day, not the next
Common causes:
- Rodents chewing wire insulation
- Corrosion in valve boxes
- Landscaping work damaging wires
Typical repair cost: $175–$400
Why this matters:
Wiring issues create unpredictable problems that are hard to diagnose without testing.
8) Spring startup damage from winter freezes
Even properly winterized systems can suffer freeze-related issues.
Common failures:
- Cracked fittings
- Split pipes
- Damaged valves
Typical repair cost: $200–$600+
Why spring reveals this:
Freeze damage often stays hidden until pressure is restored.
Problems homeowners should never ignore
Some issues deserve immediate attention:
- Zones that won’t shut off
- Rapid pressure loss
- Sudden soggy areas
- Electrical burning smells near controllers
Ignoring these can turn small repairs into major ones.
Why early spring inspections save money
Catching issues early:
- Reduces water waste
- Prevents lawn damage
- Avoids emergency repairs
- Extends system life
Most spring issues are minor when addressed quickly.
Questions homeowners should ask every spring
- Did all zones run correctly?
- Was coverage even?
- Did pressure feel normal?
- Are any areas consistently wet or dry?
If the answer to any of those is no, it’s worth investigating.
Bob Carr’s spring advice
Every spring, we see homeowners stress over sprinkler problems that could have been simple fixes — and we see small issues turn into expensive ones because they were ignored.
The goal isn’t perfection. It’s awareness.
Run your system. Watch it. Walk the yard.
Most sprinkler problems announce themselves early — if you know what to look for.
Final thoughts
Spring sprinkler problems are common, predictable, and usually fixable.
The key is understanding what you’re seeing and acting before it escalates.
At TLC Incorporated, we believe informed homeowners make better decisions — and that’s why we’re always willing to explain what’s happening and why.
