Tree Roots in PDC

An example of tree roots growing into a private drain connection.A common cause of basement flooding is the pipe connecting your home to the sanitary sewer on the street, known as your private drain connection (PDC)/building sewer, can become blocked and/or clogged. This blockage is usually caused by:

  • Tree roots growing into the pipe and/or
  • Too much FOG build-up in the pipe

Tree roots grow into pipes because they like the moisture found in the pipe.  They find their way in through cracks and joints.  If this happens, a blockage could occur causing water in this pipe to back up into your basement.  This water could be clear, dirty or smelly.
