Sewer Backup

A flood of sewage into your basement is dangerous to your health and costly to repair. Installing a backflow prevention valve can help prevent flooding. If you live in a low-lying area, you may want to consider buying sewer backup insurance.

Across the country, communities are experiencing more severe weather, especially intense rainfalls. Sudden downpours overburden sewers and stormwater infrastructure and lead to sewage backing up into homes.

Sewer Backup Insurance

This coverage is useful in some low-lying areas, especially if your area has combined storm and sanitary sewers. You may also want to install a backflow prevention device or valve, if it is permitted by local codes.

Before purchasing sewer backup insurance, you should consider:

Your existing elevation relative to sea level
Neighbourhood density relative to the size of your sewer line
Frequency of severe weather in your neighbourhood and how often sewer backups have been reported.

For more information about your coverage options, talk to your insurance representative.

How a Backflow Prevention Device/Valve Helps Prevent Flooding

A mainline backflow prevention valve can help prevent sewage in an overloaded main sewer line from backing up into your basement. Placed directly into the sewer lateral at the foot of your basement wall, the valve automatically closes if sewage backs up from the main sewer.
