Help protect your home and prevent issues from happening in the first place

Installed by a plumber directly onto your water line, a flow-based water leak detection device monitors the flow of water throughout your home. If an unusual activity or flow of water is detected – probably caused by a leak somewhere in your plumbing or pipes – the device will alert you first and then shut off your water supply to help minimize damage.

Devices to help protect your home from water damage

To choose the water shut-off device that works for you, consider one of the four Chubb-preferred devices.

Once you install one, you can receive a discount on the device and on the cost of your Chubb homeowner’s insurance.
