How do I manually open a valve?

FAQs, Troubleshooting, Video

There are two ways to bleed a zone valve for manual operation:

  • One way is to simply turn the solenoid (the black cylinder with 2 wires) counter-clockwise a 1/4 to 1/2 turn. To shut off the valve, twist the solenoid clockwise until it is snug on the valve.
  • The other way is to use the bleed screw the same way, loosen the screw enough to realease air (1/4 to 1/2 turn). Hand tighten the screw to shut the valve off.
