Basement flooding is on the rise in Ontario. Every home is at risk of basement flooding, even if it has not happened before. Water in your basement is most likely to occur during heavy rainfall or when snow and ice are melting, but you can take steps to help reduce or prevent it from happening.
Early detection of water leakage can help you quickly determine the cause and source of the leak and address it before flooding occurs.
Flood alarms, also known as flood detectors, water alarms or water detectors are electronic devices that detect the presence of water and set off an alarm when its sensors are triggered. Flood alarms come in different shapes and sizes as well as a wide range of features. New models have Wi-Fi capabilities with smart home integration.
There are two categories of flood alarms:
- Spot detectors – These alarms have sensors that require moisture or water to come into contact with the device for the alarm to activate
- Area detectors – These alarms use sensor wires with long cables and/or multiple sensors to detect floods over larger areas
What to look for
- An alarm with batteries that will work even if power is affected during extreme weather. Remember to check your units annually to ensure the batteries are functional
- Alarms with Wi-Fi connectivity that will send alerts via text or email
Things to consider
- Alarms can be placed near appliances that can leak (e.g., dishwasher, washer, etc.)
- Take other measures around your home to prevent basement flooding, including installing a sump pump and backflow valve, and disconnecting your downspouts
- Work with a plumber to install an automatic mainline water shutoff valve to block the flow of water into your home
