basement drain clogged

Because the basement floor drain sits at the lowest point of your plumbing system, it acts as the path of least resistance. When you turn on any tap, flush a toilet, or run an appliance upstairs, wastewater travels down and has nowhere to go because the main line is obstructed. As a result, it backs up and overflows out of the basement drain. Why Your Snake/Auger Didn't Work If you were using a standard hand snake or a small DIY auger through a sink, tub, or the basement drain itself, it likely failed for a few reasons: Distance: The blockage is likely further down the line—potentially many feet out toward the property line, past where a short cable can reach.  Cable Size and Rigidity: Main sewer lines typically require heavy-duty, motorized augers (drum or sectional machines) with thick cables and proper cutting heads to punch through tough obstructions like tree roots, heavy grease, or collapsed sections. A light hand snake will often just twist, coil up inside the pipe, or slip past the obstruction without clearing it.  The Wrong Entry Point: Clearing a main line effectively usually requires accessing the main sewer cleanout (typically located in the basement utility area, garage, or outside near the foundation) rather than a secondary drain.

You are experiencing a classic symptom of a main sewer line clog. Because the basement floor drain sits at the lowest point of your home's plumbing system, it acts as the path of least resistance. When the main line is blocked, any water used upstairs has nowhere to go and backs up at this lowest exit. Since a standard hand auger/snake did not work, the blockage is likely further down the line or too stubborn for DIY tools. Most Likely Causes: Main Line Blockage: A buildup of grease, wet wipes, or foreign objects deep in the pipe where a standard household snake cannot reach. Tree Root Intrusion: Tree roots frequently grow into underground pipe joints, acting as a net that completely blocks wastewater. Pipe Collapsing or Shifting: Older clay or cast-iron pipes can sag or break over time, obstructing the flow. Recommended Steps to Resolve This: Step 1: Stop all water usage immediately. Do not run the dishwasher, washing machine, showers, or flush toilets. Every drop of water used upstairs will continue to overflow into your basement. Step 2: Check with your municipality. Before hiring a private company, contact your city/town plumbing department. If the blockage is on the city’s side of the property line, they will usually clear it for free. Step 3: Call a pro for Hydro-Jetting & Camera Inspection. You need a professional plumber with a heavy-duty motorized drain snake or a hydro-jetter (high-pressure water cleaner). Crucially, insist on a sewer camera inspection right after clearing the line to see exactly what caused the block (roots, grease, or broken pipe) so you can prevent it from happening again.

Water backing up into the basement drain whenever any fixture in the house is used indicates a main building sewer blockage, rather than a localized fixture clog. A standard hand auger is usually ineffective here because the blockage is likely deep in the main line or municipal connection. ​Key Troubleshooting & Action Steps: ​Cease Water Use Immediately: Stop running all taps, flushing toilets, and using washing machines to prevent sewage backup and potential property damage in your basement. ​Locate the Main Cleanout: Find your building's sanitary main cleanout plug in the basement to check for backing or allow a professional to clear the line directly. ​Professional Camera & Hydro-Scouring: Contact a licensed plumber immediately to perform a video camera inspection of the main drain line to identify whether the blockage is caused by root intrusion, pipe collapse, or a heavy grease/scale buildup, and clear it using a motorized commercial auger or high-pressure hydro-jet. ​Under the Ontario Building Code (OBC), proper venting and sanitary drainage design prevent these cross-backups, but an obstructed main line requires professional intervention to clear safely.

This means your underground sanitary system is completely clogged, it needs to be cleared from the vertical of the main stack, and all of the under ground to the streets sanitary system. feel free to contact us at kerseymechanical@gmail.com

Sounds like the main drain line is blocked somewhere. If a regular snake didnt clear it, you may need a longer machine snake or a camera inspection to find where the blockage is.
