Common Reasons Why Sewage Comes Through Bathtub Drains

When it Comes to Bathtub Drains, We’ve Seen It All at A. Maurais & Sons, Inc.

This month, we’re sharing common reasons why sewage comes through bathtub drains. Soaking in a bathtub is supposed to be a relaxing and enjoyable experience. However, if sewage comes up through the bathtub drain, that relaxing experience is anything but! If you’re experiencing sewage coming up through your bathtub drain, A. Maurais & Sons, Inc., can explain why.



Sewage in Bathtub Drains Means Your Sewer Lines are Likely Damaged or Clogged

Everything you send down a drain, including sewage, leaves your home through your sewer lines. Therefore, if you’re seeing sewage come up through your bathtub drain, it indicates a problem with those sewer lines. Sometimes, your sewer lines clog due to gunk buildup or obstructions. Other times, you have damaged sewer lines; the latter is more serious than the former.


Gunk Buildup and Obstructions Can Clog and Damage Sewer Lines 

The most common ways that sewer lines cause sewage to come into your bathtub are because of gunk buildup and obstructions. Both gunk buildup and obstructions clog sewer lines, sometimes so badly that the lines need repaired. Gunk buildup includes soap scum and cooking grease. Common obstructions in sewer lines are usually foreign objects that shouldn’t be in the lines in the first place. In our March blog, we shared a list of these obstructions, a.k.a. non-flushable items. Your sewer lines might be causing sewage to backup into your bathtub if you’ve flushed:


  • Cat Litter
  • Cigarette Butts
  • Condoms
  • Cotton Swabs
  • Dental Floss
  • Facial Tissues
  • Flushable Wipes
  • Gum
  • Hair
  • Tampons
