What To Do When Main Sewer Line Clogs
Follow these steps if you think your main sewer line is clogged and causing water to backup in your basement:
Look for Water Backup At the Floor Drain
A blocked main sewer line often causes problems in the basement first. Check floor drains and lower-level fixtures for pooling water or slow drainage.
Stop Running Water
Turn off faucets, avoid flushing toilets, and don’t use dishwashers or washing machines. Additional water can force more sewage back into your home’s drains.
Avoid DIY Drain Clearing
Household plungers and chemical cleaners won’t fix a clogged main sewer line. Raw sewage should never be handled without proper protective equipment.

How We Handle Sewer Line Backups
Drain Camera Inspections
We use high-resolution drain cameras to see exactly what’s happening inside your pipes. Drain camera inspections help us locate clogs, cracks, or root intrusion without any guesswork or digging.
Safe Cleaning Techniques
Depending on what we find, we’ll use advanced clogged drain cleaning techniques to break up blockages. In tougher cases, we may recommend hydro jetting to flush out debris deep in the line.
Sewer Line Blockage Repair
Our technicians start every sewer line blockage repair by confirming where the blockage is and what’s causing it. We then use mechanical clearing or pipe repair techniques to restore proper flow.
Backwater Valve Installation
To help prevent future issues, we can install a backwater valve – a one-way device that stops sewage from backing up into your basement. If your home is at risk, this is one of the most effective upgrades you can make.
Basement Flooding Prevention in Richmond Hill
A few simple preventative steps can help lower your risk and help prevent basement flooding:
- Keep your sump pump in good working condition and test it regularly.
- Never pour grease, fats, or food scraps down your kitchen drain.
- Schedule periodic sewer camera inspections to catch small problems before they become expensive repairs.
Water damage continues to be one of Canada’s most common home insurance claims. Serious basement flooding can easily cost tens of thousands of dollars once cleanup, drying, repairs, and replacing damaged belongings are included.
