How to Clear a Sewer Line Clog

Water pouring through a clogged pipe

A main sewer line clog can affect your whole house—slowing down every drain in your home and causing nasty backups. If left alone, a main sewer line clog could lead to serious water damage, but clearing a main sewer line clog can be very dangerous.

While it’s not recommended that you try to clear any main sewer line on your own, you might try a few home remedies to rule out a clog in your smaller connecting lines before calling a plumber.

  • Plunge on in: Wherever you notice a slow drain—your toilet, your sink, or your bathtub—use a plunger to try to shake loose any obstructions that are within that line. If the high-water levels and slow drains subside, your plunging may have done the trick.
  • Snake it up: Slowly twist a drain snake clockwise into the drain that you believe is obstructed. As you pull the snake out, twist counterclockwise. Use caution, as drain snakes can break off in your drain. If, as you pull the snake back out, you draw out a mass of what you believe was causing a clog, you might have successfully cleaned what was affecting your smaller connecting line.
  • Check the vent: Sometimes, if an obstruction is blocking your vent pipe, pressure will prevent your drains from draining down your main sewer line. To release the pressure, head up to your roof and clear your vent of any obstructions by using a retrieval tool, garden hose, or drain snake.
