Emergency Irrigation: What to Do Before the Technician Arrives

A broken irrigation pipe or a valve stuck in the open position isn't just a nuisance—it's a plumbing emergency that can flood your yard, erode your topsoil, and send your municipal water bill skyrocketing within hours. While Campbell's Irrigation & Wells offers rapid emergency repair services, taking immediate, decisive action before our technician arrives is critical to protecting your property.

Don't panic. Follow this step-by-step emergency irrigation guide to safely secure your system and prepare for a professional repair.

Step 1: Shut Off the Water at the Controller

If a sprinkler zone refuses to shut off, the first place to check is your automatic irrigation controller (often located in the garage, on an exterior wall, or in a utility shed).

• Turn the main dial from "Run" or "Auto" to the "Off" or "Stop" position.
• Wait 30 to 60 seconds. Sometimes, older mechanical valves take a moment to close after the electrical signal is cut.
• If the water successfully stops, your issue is likely electrical—such as a faulty solenoid, a shorted wire, or a programming error in the controller.

Step 2: Locate and Close the Main Isolation Valve

If turning off the controller has no effect, you are dealing with a mechanical failure. A piece of debris may be wedged inside a valve diaphragm, preventing it from closing, or an underground PVC main line may have shattered. You must physically cut off the water supply to the irrigation system.

Search for your irrigation isolation valve or backflow preventer device. This is usually located near your primary water meter, close to the street, or hugging the side of your house. To shut off the water, turn the ball valve handle so that it is perpendicular (at a 90-degree angle) to the pipe. This will stop the flow of water to the sprinkler system without shutting off the drinking water to your home.

Step 3: Document the Damage Safely

Before the flooded area drains and dries up, carefully document the scene. Take a short video or photos on your smartphone showing exactly where the water was pooling or spraying from. Ask yourself:

• Was the water shooting out of a specific sprinkler head?
• Was a rectangular green valve box completely submerged in water?
• Was water bubbling up through a random patch of mud in the grass?

This visual evidence acts as an X-ray for our technicians, allowing them to instantly diagnose the source of the leak when they arrive, saving you diagnostic time and money.

Step 4: Do Not Dig Blindly

It is highly tempting to grab a shovel and dig into the mud to locate a broken pipe yourself. Resist this urge. Aggressively digging in muddy, low-visibility conditions is the leading cause of secondary irrigation damage. A shovel strike can easily slice through adjacent PVC laterals, sever low-voltage valve wiring, or even damage critical utility lines. Leave the excavation to the professionals.
