Water and flood sensors are designed to detect water and will trigger an alarm if detection is made. The sensors can be stand-alone or can work (depending on model and design) with a phone dialer, a home alarm, or with an environmental control system. As well, water and flood sensors can also be integrated with a valve control unit that shuts off a given water line when prompted.
The less expensive water and flood sensors will simply sound an alarm and not actually stop the leak. The sensors will give an early warning sign that a leak needs urgent attention. This will give you some time to move valuable furniture and belongings out of the way.
It is best to install your water and flood sensors in leak prone areas such as behind the washing machine, dishwasher, water heater, and underneath sinks. This will prevent, or at least limit, the damage that is often the result of unseen and normally undetected leaks, drips, and appliance failure. There are also sensors made for a specific appliance, for example – for an ice maker or for a washing machine (which is the number one cause of water damage in American households).
Also, make sure that the water and flood sensors you buy will not trigger an alarm due to condensation or high humidity.
Flooding events can often go undetected for hours or even days, causing extensive damage to your home and personal belongings. Receiving an early warning of a water leak can mean all the difference!
