5 Signs Your Sprinkler System Has a Leak (And What to Do)
A leaking sprinkler system isn't just annoying—it's expensive. The average underground leak wastes 3,000-5,000 gallons per month, adding $30-$50 to your water bill. Worse, undetected leaks can cause erosion, foundation issues, and landscape damage.
The good news? Most leaks show clear warning signs long before they become disasters. Here's how to spot them and what to do.
Sign #1: Soggy or Muddy Spots in Your Yard
What to Look For:
Areas that stay wet even when you haven't run your system. You'll often see:
Standing water between watering cycles
Muddy patches when surrounding areas are dry
Sinking or soft spots in the grass
Unusual green patches (grass loves the extra water)
What It Means:
Underground pipe leak, broken fitting, or damaged valve. Water is escaping below ground and pooling at the surface.
Urgency Level:Medium to High
Small leaks grow. That soggy spot today becomes a washed-out crater next month.
What to Do:
Mark the location with spray paint or a flag
Turn off your irrigation system
Call SprinklerSavers at (651) 371-9722
Take photos to show our technician
Typical Repair:Pipe leak repairs run $300-$600 depending on depth and location.
Sign #2: Unusually High Water Bills
What to Look For:
Your water bill jumps 20-50% or more with no change in usage habits.
Detective Work:
Check your water meter before bed
Don't use any water overnight
Check the meter in the morning
If it moved, you have a leak somewhere
What It Means:
Constant water flow indicates a leak. Could be:
Broken lateral pipe
Stuck valve
Damaged mainline
The Cost:
A 1/4" hole in a pipe can waste 15,000 gallons per month. That's $150+ on your water bill in Cottage Grove.
Urgency Level:High
Every day you wait costs real money.
What to Do:
Shut off irrigation main valve immediately
Call for emergency service: (651) 371-9722
Take photos of recent water bills
Request meter reading verification from your utility
Sign #3: Low Pressure or Dry Zones
What to Look For:
Certain zones barely spray
Heads that used to shoot 15 feet now dribble
Brown spots appearing in previously healthy areas
Some zones work fine, others are weak
What It Means:
Water is escaping before it reaches the heads. Common causes:
Underground leak reducing system pressure
Cracked lateral line
Damaged valve not opening fully
Why It Matters:
Yes, you have a leak. But you're also underwatering part of your lawn, causing brown spots and stressed grass.
Urgency Level:Medium
Your lawn is suffering, but immediate property damage is unlikely.
What to Do:
Run each zone and note which are affected
Look for soggy spots along those zone lines
Schedule diagnostic service
Don't overwater other zones trying to compensate
Typical Repair:Zone-specific repairs run $200-$500.
Sign #4: Hissing or Bubbling Sounds
What to Look For:
Listen carefully around:
Valve boxes
Backflow preventer
Areas where pipes run shallow
You might hear:
Constant hissing (even when system is "off")
Gurgling or bubbling sounds
Running water underground
What It Means:
Active leak or stuck valve. Water is flowing when it shouldn't be.
The Problem:
If you hear it, it's already significant. Small leaks don't make noise.
Urgency Level:High
Constant flow means constant waste and potential property damage.
What to Do:
Shut off your irrigation main valve immediately
Locate the sound as precisely as possible
Mark the area
Call for same-day service: (651) 371-9722
Sign #5: Visible Water Pooling or Geyser
What to Look For:
This one's obvious:
Water shooting up from the ground
Mini-geyser near a sprinkler head
Large pools forming quickly
Water running down the street
What It Means:
Major break in mainline or lateral pipe. This is as bad as it gets.
Common Causes:
Freeze damage from skipped winterization
Tree root intrusion
Ground settling
Age-related pipe failure
Urgency Level:EMERGENCY
You're wasting hundreds of gallons per hour and risk property damage.
What to Do:
IMMEDIATELYshut off irrigation main valve
Call emergency service: (651) 371-9722
If water is threatening your home or neighbor's property, also shut off main house water
Document with photos for insurance if needed
Keep people and pets away from the area
