Sewer Backup & Main Drain Repair in Calgary

1. Tree Root Intrusion

In many of Calgary’s older neighborhoods, tree roots are a frequent culprit behind sewer backups. Roots naturally seek moisture and can infiltrate small cracks or joints in underground sewer pipes. Once inside, they grow and create dense blockages that disrupt wastewater flow, causing slow drains, strange gurgling noises, and eventually, serious backups.

Delta Plumbers Calgary uses advanced camera inspection technology to pinpoint root intrusion with precision. We then clear the blockage using motorized drain snakes or specialized root-cutting blades. For severe cases, we apply hydrojetting, which blasts away roots and debris using high-pressure water. We also advise on preventive solutions like root barriers and trenchless pipe repair to protect your plumbing long-term. This expertise is what sets the best Calgary plumbers apart.

Our Calgary plumbing team is fully equipped for safe, effective root removal and lasting sewer line restoration—schedule your inspection today.

2. Main Drain Sewer Line Blockage

Blockages in your home’s main sewer line—the pipe connecting to the city system—can cause widespread backups affecting toilets, showers, and floor drains. Common causes include grease buildup, tree roots, wipes, sanitary products, and other materials that shouldn’t be flushed.

Our expert Calgary plumbers start with a full diagnostic, often using drain cameras, to locate and identify the blockage. Depending on the issue, we use snaking or hydrojetting to clear minor and stubborn clogs alike. Hydrojetting thoroughly cleans pipe interiors, reducing the risk of future blockages. When necessary, we also recommend trenchless sewer line repair or replacement, avoiding costly excavation. Homeowners trust us for reliable, long-term plumbing solutions.

Don’t risk a whole-house backup—our Calgary plumbing team specializes in complete sewer line clearing for homes of all sizes.

3. Basement Drain Backup

Basement drain backups happen when clogs in your sewer line force wastewater to flow back into your home’s lowest point—the basement. These incidents can cause serious damage to flooring, walls, and belongings, while exposing your family to harmful contaminants.

We treat basement backups as plumbing emergencies, prioritizing a fast response. On arrival, our Calgary plumbers perform immediate blockage removal using augers or drain snakes. We inspect your main sewer line for damage or collapse with camera equipment and offer backwater valve installation to prevent future backups, especially in flood-prone areas of Calgary. This is a standard recommendation from any reputable Calgary plumber.

4. Overflowing Toilets and Fixtures

If flushing your toilet causes water to rise in sinks, tubs, or other drains, it’s a clear sign of a sewer line clog affecting multiple fixtures. These blockages require immediate attention to prevent widespread water damage.

Our Calgary plumbers use advanced flow testing and video inspection to isolate the problem area. We then employ motorized snaking or hydrojetting to clear the blockage completely. After repairs, we clean and sanitize affected fixtures and provide tips to help you maintain clear, healthy pipes—expert care you can expect from trusted Calgary plumbing professionals.

5. Grease Buildup

Grease, oils, and fats from cooking may wash down your drain as liquids but solidify once they cool inside your pipes. Over time, this buildup narrows pipe openings and causes stubborn clogs, often near kitchen sinks but sometimes deep in the sewer line.

After a thorough camera inspection, our Calgary plumbing experts pinpoint grease blockages. We use powerful hydrojetting to blast away hardened residue without damaging your pipes. We also advise on proper grease disposal and can install grease traps when necessary, preventing future buildup. This proactive service is why Calgary homeowners rely on us as their go-to plumbing company.

Grease-related clogs are a top cause of plumbing calls in Calgary—our hydrojetting clears pipes safely, chemical-free, and effectively.

6. Collapsed or Damaged Sewer Pipes

Many older Calgary homes still have clay or cast-iron sewer pipes that deteriorate over time, causing pipe collapse or breaks. This leads to recurring backups, foul odors, and slow drainage throughout your home.

We perform high-resolution sewer camera inspections to identify structural pipe damage. When needed, we use trenchless sewer repair or pipe bursting to replace damaged sections with minimal digging. This modern technique is faster, cleaner, and often more affordable than traditional excavation—offering Calgary homeowners a hassle-free solution.

7. Municipal Sewer System Blockage

Heavy rains and rapid snowmelt in Calgary can overwhelm the city’s sewer system, causing backups in private homes through floor drains or basement toilets.

While the municipal system is out of homeowners’ control, we help reduce your home’s vulnerability by recommending and installing backwater valves. These devices prevent sewer water from flowing back into your home when city lines are overloaded. We also evaluate your drainage setup to ensure it meets local codes and offers maximum protection—expert services only trusted Calgary plumbers can provide.

Installing a backwater valve is one of the best preventative measures Calgary plumbers recommend to safeguard homes from city sewer backups.
