Sprinkler Repair: A Step-by-Step Guide



The spring sun has risen, and your lawn is ready to show off its green expanse. But wait! You turn on your sprinkler system, and there’s an unexpected geyser, a section not getting any water, or perhaps it’s not even turning on. You’re not alone. Sprinkler systems, like any other household mechanism, require periodic attention and may run into occasional hiccups. In this blog post, we’ll delve deep into the step-by-step guide on sprinkler repair.

Step 1: Diagnosis is Key Before you dive in, you need to figure out the root cause of the problem. Understand if it’s a simple issue like a blocked nozzle, a broken sprinkler head, or a more intricate one involving the control system.

Step 2: Safety First Before making any repairs, make sure the water supply to the system is turned off. You wouldn’t want a surprise shower!

Step 3: Check the Sprinkler Heads Sprinkler heads can easily get damaged by lawn mowers or become clogged with dirt and debris. Here’s how to address it:

  1. Cleaning a Clogged Head: Remove the sprinkler head from its riser (the vertical pipe). You should be able to simply unscrew it. Clean out any debris, dirt, or grass clippings. Once cleared, screw it back onto the riser.
  2. Replacing a Broken Head: If the sprinkler head is cracked or damaged, you’ll need to replace it. Unscrew the broken head from the riser and replace it with a new one that matches the old head’s type and size.

Step 4: Examine the Valves The valves control the water flow through the sprinkler system. If a zone isn’t getting water, it might be due to a malfunctioning valve.

  1. Check the solenoid on the valve; it’s a cylindrical object with wires. If it’s not functioning, the valve won’t open. Try manually turning the solenoid to see if the valve opens. If it doesn’t, the solenoid may need replacement.
  2. If the solenoid is working but the zone isn’t getting water, debris might be blocking the valve. In this case, you’d have to turn off the water, disassemble the valve and clean out any obstructions.

Step 5: Monitor the Pressure If multiple sprinkler heads are not working or if they produce a weak spray, it could be a pressure issue. This might be due to a leak in the system or a malfunctioning pressure regulator. To handle this:

  1. Inspect the system for visible signs of leaks. Wet spots or unusually lush areas can be indications.
  2. If you find a leak in a pipe, dig around it carefully to expose a larger section. Cut out the damaged piece and replace it using couplings and a new segment of pipe.
  3. If the issue isn’t a leak, check the pressure regulator. It might need adjustment or replacement.

Step 6: Inspect the Controller Sometimes, the problem may not be in the field but at the source. The controller or timer can malfunction:

  1. Ensure the controller is getting power. If not, it might be as simple as a blown fuse or a tripped breaker.
  2. Check the wiring. Loose or damaged wires can be the culprit. If you find any, reconnect or replace them.
  3. Update or reset the programming. Sometimes, the controller might just need a soft reset.

A Few Closing Thoughts 

While these steps can guide you in diagnosing and fixing some of the common sprinkler system issues, it’s important to remember that not all repairs are DIY-friendly. Complex issues, particularly those related to electronics, wiring, or pressurized pipes, often require a professional touch.

Sprinkler systems in San Antonio are designed to keep your lawn lush and green, and routine maintenance can ensure they stay efficient. By addressing small problems as they arise, you can prevent bigger, more costly issues in the future. Remember, your lawn is an investment, and it’s always worth seeking professional help when in doubt to keep it in tip-top shape. Happy gardening!
