Installation Time: ~30–45 minutes

1. Shut Off Your Water Supply
   • Locate your main water valve and shut off the flow before starting.

   • Replace a section of the pipe near the valve with the smart valve body.
   • Use Teflon tape to ensure a leak-proof seal.
3. Connect to Power and App
   • Plug the valve controller into an outlet.
   • Pair it using the Grus app’s on-screen instructions.
