Is it safe to stay in my house with a sewage backup?

It is not recommended. Raw sewage contains harmful bacteria and viruses that can cause serious illness. It is best to vacate the affected area, especially for children and pets, until it has been professionally cleaned and sanitized.

Will my homeowners insurance cover a sewer backup?

Standard homeowners insurance policies often do not cover sewer backups. You typically need to purchase a specific add-on or endorsement for this type of coverage. Check your policy details and speak with your insurance provider to understand your coverage.

How can I tell if the blockage is in my pipes or the city's main?

If only your home is experiencing a backup, the problem is likely in your sewer lateral. If you notice your neighbours are having similar issues, the blockage is probably in the municipal sewer main. In that case, you should contact your city's public works department immediately.

How often should I have my sewer lines inspected?

For most homes, a preventative inspection every 2-3 years is sufficient. However, if you have an older home, live in an area with many mature trees, or have experienced previous backups, an annual inspection is a wise investment to catch problems early.

Can I use a plunger to fix a sewer backup in my tub?

While a plunger can clear a simple clog in the tub's local drain, it will be ineffective against a main sewer line blockage. A main line backup requires professional equipment like a motorized auger or hydro-jetter to clear the obstruction properly and safely.
