How to Test Your Sprinkler System

Testing your sprinkler system at least once a year is essential for maintaining a healthy lawn and efficient water use. Here's how to do it:

  1. Use your sprinkler timer's test feature or manual run option.
  2. For Hunter timers, hold down the forward button or the hand symbol button.
  3. Observe each station/zone and advance to the next using the forward button.
  4. Look for broken heads, misaligned sprinklers, leaks, and dry spots.
  5. Check for overwatering by looking for soft spots or water pooling on concrete.

Manual Testing of Sprinkler Valves

Two Methods for Manual Valve Operation:

  1. Solenoid Method: Turn the solenoid counter-clockwise 1/2 turn. The valve should activate within seconds.
  2. Bleeder Screw Method: Turn the bleeder screw counter-clockwise 1/2 turn. This causes a small leak, activating the valve.

To turn off, return the solenoid or bleeder to its original position. Be careful not to over-tighten, as the plastic threads can be easily damaged.

Checking Soil Moisture

A simple yet effective way to test soil moisture:

  1. Use a screwdriver to probe the soil.
  2. If it inserts easily, the area likely has adequate water.
  3. If there's significant resistance, the area may need more water.

This method helps you fine-tune your sprinkler system for optimal lawn health and water conservation.
