A broken sprinkler pipe wastes water, damages your landscape, and increases repair costs. The fix? Shut off the water, cut out the damaged section, and replace it with a new pipe.
This guide walks you through the process step by step, covering common causes, essential tools, and tips for a durable repair.
Common Causes of Broken Sprinkler Pipes
Freezing Temperatures: Water expands when frozen, cracking pipes.
Physical Damage: Lawn mowers, shovels, and pets can break pipes.
Aging Pipes: UV exposure and material wear weaken pipes over time.
High Water Pressure: Excessive pressure can cause leaks or bursts.
Improper Installation: Poor connections increase failure risk.
Tools and Materials Needed
Tools:
Pipe cutter or hacksaw
Adjustable wrench
Measuring tape
Shovel (if digging is needed)
Materials:
Replacement pipe sections or connectors
PVC primer and cement (for PVC pipes)
Pipe fittings (elbows, couplings, tees)
Teflon tape (for threaded connections)
Shut-off valve (if needed)
Step-by-Step Repair Guide
1. Shut Off Water Supply
Close the sprinkler system valve and depressurize the pipes.
2. Locate the Break
Dig to expose the damaged section. If unclear, run water briefly to pinpoint the leak.
3. Cut Out the Damaged Pipe
Mark and cut out the broken section cleanly with a pipe cutter or hacksaw.
4. Prepare the Replacement Pipe
Measure and cut a new pipe section. Clean pipe ends and fittings for a secure seal.
5. Install the New Section
Apply PVC primer and cement if using PVC pipes. Connect the replacement piece, holding it in place briefly for a strong bond.
6. Reconnect and Secure
Use appropriate fittings (elbows, tees, couplings) to restore the connection. Tighten securely but avoid overtightening.
7. Test the System
Turn the water back on and check for leaks. Run a few cycles to ensure proper function and pressure.
Tips for a Successful Repair
Allow PVC cement to dry for 10–15 minutes before turning on water.
Use the correct pipe type and size for a proper fit.
Check for other weak spots while repairing.
Install a pressure regulator if high water pressure is an issue.
Common Mistakes to Avoid
Not fully shutting off the water before cutting the pipe.
Using dull or incorrect tools, leading to uneven cuts.
Rushing the cement drying process, causing weak seals.
Skipping a leak test, which can lead to further repairs.
When to Call a Professional
If the break is deeply buried or hard to reach.
If there are multiple leaks or widespread damage.
If working with non-PVC pipes like polyethylene or copper.
If you’re uncertain about high-pressure systems.
Preventative Maintenance Tips
Inspect pipes regularly for cracks or leaks.
Winterize the system by draining pipes before freezing temperatures hit.
Monitor water pressure and install regulators if needed.
Protect pipes from impact when mowing or digging.
