how do i turn on my in ground sprinklers at the start of season?

Answer 1

Make sure the backflow valves are open and the blowout plug is tight. Turn the water on. Then turn on and set the controller. Go through the zones 1 at a time and check to make sure that every head is rotating and adjusted, and check for leaks. If you have a rain sensor, check it manually to see if it works.

Answer 2

You just turn on the sprinkler system at the computereized base, usually located in the garage or utility area. The heads should pop up from the force of the water.
