New Valves Won't Follow Timer: Landscaper Left Flow Controls Closed

After landscaping, the owner manually opened valves per instructions. Sprinklers run but won't shut off per timer—only manual valve closure stops them.

Flow Control Adjustment

1. On each valve, open flow control fully.
2. Close fully, counting turns.
3. Reopen to half the turns (50%).

This sets the valve's opening speed and closing force. Fully open flow control can prevent reliable solenoid closure.

Landscaper Responsibility

Completing the installation includes verifying automatic operation. Contact the landscaper to correct this. If unresponsive, file a complaint with the state contractor licensing board.
