Flood Alarms

Basement flooding is on the rise in Ottawa. 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 a heavy rainfall, or when snow and ice is 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 and with a wide range of features. New models have WiFi capabilities with smart home integration.

There are two categories of flood alarms:

  • spot detectors, have sensors that require moisture or water to come in contact with the device for the alarm to activate
  • area detectors, 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 the power is affected during extreme weather. Remember to check  your units annually, to make sure the batteries are functional.
  • Alarms with WiFi 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, a 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.
