Reduce your risk of basement flooding
Follow these tips:
- Slow drains can be caused by root infiltration, damaged connection pipe or sewer main back up; have slow drains inspected and repaired.
- Reduce the amount of fats, oils and grease poured down the drain.
- Avoid putting non-flushable materials into your toilet. Learn more about what not to flush in our sanitary sewer system.

Are there sewer odours in your basement?
If you are experiencing sewer odours in your basement, it could be possible that the odours are entering through your basement floor drain.
Your basement floor drain has a water trap under the drain. When the trap is filled with water, it creates a seal which prevents odours from entering your basement. Over time, this water in the trap can evaporate, which causes the odour.
Pour a pitcher full of water down the floor drain to ensure that the water trap is full.
