What causes an alarm?
A flood sensor will go into alarm when it comes into contact with water. These devices are commonly installed near hot water tanks, toilets, and appliances. Some models require a minimum amount of time being submerged before alarming, so be sure to ask how much water is required when considering this type of device.
Sump Water Level Sensors
Sump Sensors generate an alarm when the water level in your sump rises to a level that will trigger the float sensor. The alarm could indicate that your sump pump is not working at all, or is unable to pump out water as quickly as it is coming in. With this device being triggered before the water has left the sump, you have a head start to stop the flooding before it starts.
Ensuring good drainage, Inspecting your property regularly, and testing your sump pump year round can all help to ensure that your home remains dry, but when things go wrong, monitored sensors help limit or prevent damage.
