Wet checks are completed to prevent further issues with your sprinkler system. They are the first step you should take to potentially address problems with water flow, pressure, and leaks. Wet checks include:

Activating the system, zone by zone, to ensure all zones are turning on/off.
Inspecting the rain sensor for proper operation.
Programing the controller’s settings for seasonality.
Examining each zone for any broken or malfunctioning sprinkler heads
Adjusting any misaligned heads for proper coverage.
Cleaning and adjusting sprinklers to ensure optimal spray coverage.
Examining the system and yard for dry spots and possible leaks.
Identifying all heads that need to be raised, lowered, or moved.
Presenting diagnostic findings and making recommendations for repairs and improvements.
