Seasonal Management of Your Sprinkler System

Your sprinkler system will need to be winterized to avoid freeze damage. In our Pacific Northwest climate this will usually be necessary around November. Observe the simple procedure which follows to ensure that your spinkler system suffers no damage.

  1. Close the main shut-off valve (brass valve with X handle on top)
  2. Open test cocks 1, 2, 3, and 4 (smaller valves that point upward)
  3. Turn shut-off valve handles to 45 degree angle (2 valves with blue handles)
  4. Open all drains in electric valve boxes (small brass valve with X handle)

As spring approaches, it will be time to prepare your sprinkler system for operation. Since the risk of a hard freeze is virtually nil by April, this is a good time to re-pressurize the system. Follow the steps which follow to get your system ready for watering.

  1. Close all drains in electric valve boxes
  2. Turn shut-off handles on
  3. Close test cocks 1, 2, 3, and 4
  4. Open main shut-off valve slowly to re-pressurize the system
