How much water can a leak waste?

Even a small crack in a 1/2-inch pipe can waste over 6,000 gallons of water per month. A main line break can waste that much in a single night.

Do you fix leaks under concrete?

We focus on landscape irrigation leaks. If a leak is under a driveway or patio, we can often reroute the pipe around the hardscape to avoid breaking the concrete.

What is Leak Detection & Repair?

Irrigation leak detection uses pressure testing and isolation techniques to locate underground leaks in PVC or poly pipes. In Phoenix, high water bills are often the first sign of a silent leak in the main line or a stuck valve.

$ Typical Costs in Phoenix

Professional leak detection starts at $150 to $300 for the diagnostic service. Repair costs are separate and depend on the leak's location (e.g., under a sidewalk vs. in open dirt).

Our Leak Detection & Repair Process

Step 1: Meter Test

We monitor the water meter with the house water off to confirm the leak is in the irrigation system.

Step 2: Isolation

We shut off the backflow and master valve to determine if the leak is in the main line or a zone.

Step 3: Visual/Audio Search

We look for wet spots and listen for the sound of running water to pinpoint the break.

Step 4: Excavation & Repair

We carefully dig to expose the pipe and repair the break with new fittings.

Stop Water Waste with Expert Leak Detection

A hidden irrigation leak can waste thousands of gallons of water and damage your home's foundation. At PHX Irrigation Repair, we use a combination of visual inspection and pressure testing to identify and fix leaks in your sprinkler and drip systems.

Signs You Have a Leak

Unexplained High Water Bill: A sudden spike in usage is the #1 indicator of a leak.
Wet Spots or Mud: Soft, muddy areas in your yard when the system hasn't run recently.
Low Pressure: Sprinkler heads that don't pop up fully or weak drip flow.
Hissing Sounds: A constant noise coming from the valve box or backflow preventer.

Our Leak Repair Process

We isolate the leak to a specific zone or the main line. Once located, we excavate carefully to expose the pipe, cut out the damaged section, and install a permanent repair using professional-grade PVC or poly fittings. We then test the system to ensure the leak is completely resolved before backfilling.
