Like any other pipe, your sewer lines become at higher risk of freezing when the colder weather approaches. If you own a home or building, make sure you’re taking the necessary steps to prepare for the frigid winter temperatures.

Here is everything you need to know to protect your sewer lines this winter:

What Causes Your Sewer Lines to Freeze?

Water can get trapped in your sewer lines, causing them to freeze when temperatures drop below 0. Freezing temperatures will cause water to expand, freeze, and cause blockages inside of the pipe. In more severe cases, the blockage can eventually form into a crack or break.

If a crack or break forms, this can temporarily close down your draining system until the ice melts or until you seek professional help.

Other Causes of a Frozen Sewer Line

There are a few things that can cause a sewer line to freeze. As an additional safety precaution, it’s always wise to know where your sewer pipes are located.

Some of the most common causes include:

  • Faulty insulation around the pipes
  • Sudden drops in temperature
  • Lack of water flow in an exposed drain
  • Malfunction in the home thermostat or heating system

How Can You Tell If Your Pipes are Frozen?

There are a few ways to tell that your sewer lines are frozen. The sooner you recognize these signs, the more quickly you can fix the problem before it turns into a bigger problem.

Here are the following signs you should look out for: 

  • Flooding or damp walls/ceilings
