System Turn On/Off


Required For The Proper Operation of Your System
Sprinkler systems need to be turned on and checked in the Spring, and drained and turned-off in the Fall.
Spring Turn-On Service
  • Turn on water, shut off any open drains, and pressurize the main line.
  • Activate each zone and conduct a manual inspection of your system.
  • Adjust heads to ensure proper coverage.
  • Check for leaks and damaged nozzles and heads.
  • Review and set watering schedule for Spring conditions.
  • Provide irrigation recommendations that are relevant for your system.

Fall Turn-Off & Drain "Winterization"

In the Kansas City area (a freezing climate) lawn sprinkler systems must be winterized to prevent freeze damage to pipes, spray heads and other equipment.

There are two standard methods by which sprinkler systems are winterized: "Blow-Out" and "Gravity-Drained".

"Blow-Out" Method, which requires a contractor:

  • Sprinkler systems requiring the blow-out method have an additional pipefitting near the water source
    that allows an air compressor to fill the pipes with air pressure.
  • The pressure and volume of air requires a large 125 CFM air compressor. Pressure should not exceed 50 psi to avoid damaging the sprinkler valves and heads. A typical home compressor delivers 3 to 5 CFM of air, and is not recommended.
  • Each station is flushed, with the air compressor running, for 2-3 minutes to allow the air to blow the water out of the pipes.
  • We'll also check for any special system winterization needs, checking faucets and the backflow preventer.

"Gravity Drain" Method (may or may not require a contractor-- the customer's choice):

  • Sprinkler systems requiring the gravity drain method are specifically designed for this.
  • The sprinkler system is installed with manual and automatic drains at low points that automatically drain water from the pipes.
  • The homeowner can drain the system themselves in 10 to 20 minutes.
  • IMPORTANT NOTE: Your system must be specifically designed for manual draining. If you're unsure about your system design, call Samson Irrigation with any questions or concerns you may have.
