Sewer Backup & Main Drain Repair in Edmonton

1. Tree Root Intrusion

In Edmonton’s older neighborhoods, tree roots are a common cause of sewer backups. Over time, roots from nearby trees can penetrate small cracks or joints in underground sewer pipes in search of moisture. Once inside, they expand and form a dense, tangled mass that blocks the flow of wastewater. This often causes slow drains, gurgling sounds, and eventually, sewage backup.

We use camera inspection technology to locate the exact point of root intrusion. Once identified, we utilize motorized drain snakes or root-cutting blades to remove the roots efficiently. In more severe cases, hydrojetting — which uses high-pressure water — is employed to blast roots and debris off pipe walls. We also advise homeowners on preventive maintenance, such as root barriers or trenchless pipe repair, to avoid future issues. This level of service is only expected from the best plumbing in Edmonton.

2. Main Drain Sewer Line Blockage

A blockage in the main sewer line, which connects your home to the municipal sewer system, can lead to widespread backup in toilets, showers, and floor drains. Common causes include grease buildup, sanitary products, tree roots, wipes, and other non-flushable materials being sent down the drain.

Our expert team, known among the best Edmonton plumbers, begins with a full system diagnostic, often using drain cameras to identify the blockage’s location and cause. Depending on the severity, we’ll use either snaking/cabling equipment for minor clogs or hydrojetting for more stubborn buildups. Hydrojetting cleans the entire inner wall of the sewer pipe, reducing the risk of recurrence. Finally, if no other solution is an option, we will recommend a drain line excavation to replace the damaged and blocked portion of the pipe — a solution trusted by those seeking reliable plumbing repair in Edmonton services.

3. Basement Drain Backup

Basement drain backups usually occur when the sewer line gets clogged and wastewater has nowhere to go but back into the lowest point of the home, typically the basement. These backups can cause extensive damage to flooring, walls, and furniture, and may contain hazardous waste.

We treat basement backups as emergencies and prioritize response time. Once on site, we perform an immediate inspection and blockage removal using augers or drain snakes. We inspect for main line issues or collapsed pipes via camera inspection. We also offer solutions such as backwater valve installation, which prevents sewage from flowing back into your home during heavy rain or line backups. This is especially recommended in flood-prone areas of Edmonton and is a standard recommendation by any reputable plumber in Edmonton.

4. Overflowing Toilets and Fixtures

A telltale sign of a sewer backup is when flushing a toilet causes water to come up through another drain, like a bathtub or sink. This usually indicates a shared clog in the sewer line that connects multiple fixtures.

Our plumbers, ranked among the best plumbers in Edmonton, use diagnostic flow testing to isolate the affected section of piping. We then deploy motorized snaking tools to break apart the obstruction or remove it entirely. In cases where the blockage lies deeper in the line, hydrojetting may be used. Once the blockage is cleared, we thoroughly clean and sanitize the affected fixtures and walk homeowners through best practices to maintain clear pipes — the kind of expert care you expect from an affordable plumber in Edmonton.

5. Grease and Fat Buildup

Grease, oils, and fats from cooking may go down the drain as liquids, but as they cool in the pipes, they harden and stick to the walls. Over time, this buildup restricts flow and eventually causes blockages, often near kitchen drains but sometimes impacting the entire sewer line.

After performing a video camera inspection, our team — part of one of the most reliable Edmonton plumbing companies — can identify the location of the blockage. For more significant cases, hydrojetting is employed. This method is ideal for grease-related backups because the high-pressure water effectively clears all residue from the pipe interior. We also provide tips on disposing of grease properly and recommend installing grease traps where necessary. Our proactive guidance reflects what you’d expect from the best Edmonton plumbers.

Grease-related clogs are a top call for Edmonton plumbing companies—our hydro jetting clears your pipes without chemicals or pipe damage.

6. Collapsed or Damaged Sewer Pipes

In older Edmonton homes, clay or cast-iron pipes can deteriorate or collapse due to age, shifting soil, or extreme weather changes. A broken pipe often results in recurring sewer backups, foul smells, and slow drains across the house.

If we suspect structural damage, we’ll perform a high-resolution sewer camera inspection to confirm the origin of the issue. If a collapse is identified, we recommend trenchless sewer repair or pipe bursting — a modern method that allows us to replace the damaged pipe with minimal digging. This is a quicker, cleaner, and often more cost-effective solution than traditional excavation — the kind of service that defines the best plumbing in Edmonton.

Our plumber in the Edmonton team uses trenchless technology to replace damaged pipes efficiently, saving time, mess, and cost for Edmonton homeowners.

7. Municipal Sewer System Overload

During heavy rainfall or sudden snow melts common in Edmonton, Alberta, the city’s sewer system may become overwhelmed, leading to backups in private homes through floor drains or basement toilets.

While homeowners can’t control the municipal system, Delta Plumbers Edmonton can help reduce your home’s vulnerability. We recommend installing backwater valves, which prevent water from flowing backward into your home when city lines are overloaded. We also assess your drainage system to ensure all fixtures are protected and compliant with city plumbing codes — something only an expert plumber in Edmonton can confidently offer.

Installing a backwater valve is a key preventative measure recommended by the best plumber Edmonton professionals to protect homes from city sewer overflow.
