Water Shut Off Valve
The Liberty Security Water Shut Off Valve is an automated Z-Wave valve controller that mounts directly onto your existing ball valve and shuts off your water supply the instant a leak is detected — or remotely via the Liberty Live app from anywhere in the world. For Canadian homeowners, an automatic water shut-off is one of the most cost-effective investments in home protection, preventing the thousands of dollars of damage a burst pipe or appliance leak can cause.
What is the Water Shut Off Valve?
It is a Z-Wave valve shut-off controller — a motorized actuator that attaches to your existing manual quarter-turn ball valve without replacing the valve itself. When your Liberty alarm system detects water via a paired Water Tile or flood sensor, an automation rule triggers the unit to close your water supply within 5–10 seconds. The unit also acts as a Z-Wave repeater, strengthening your home’s wireless signal network while delivering reliable, battery-less valve control.

Frequently Asked Questions
No. The water shut off is a motorized controller that clamps directly onto your existing manual quarter-turn ball valve — no plumbing replacement or pipe cutting required. It adds automated, remote, and sensor-triggered control to your existing valve.
When your Liberty alarm panel receives a water detection signal from a paired flood sensor or Water Tile, an automation rule triggers the unit to close your water supply — automatically, within seconds, even if you’re not home. You’ll also receive a push notification via the Liberty Live app. You can then reopen the valve remotely once the leak is resolved.
The unit is installed on your home’s main water supply valve — typically located where the water main enters your home, such as the basement utility area. Liberty’s certified technicians will assess your plumbing during installation and ensure the controller is properly aligned and configured.
Yes. The physical ball valve remains manually operable at all times — the controller can be unclamped and the valve turned by hand. The unit does not lock or disable the manual valve in any way.
The Water Shut Off is powered by 12V DC and requires continuous power to operate. Liberty recommends connecting it to a circuit protected by an uninterruptible power supply (UPS) for coverage during power outages. The physical valve remains manually operable regardless.
