Sewage in the basement

Do now

  • Tell everyone in the house: no showers, laundry, dishwasher or flushing until the line is clear.
  • Keep kids and pets out of the basement.
  • Note where the sewer cleanout is for the plumber.

Avoid

  • Skip the chemical drain opener: it won't clear a main-line block and it burns whoever snakes the line next.
  • Every flush upstairs adds more water to the basement.

Call: Right away: sewage at a floor drain means the main line is blocked.

Basement Sewer Backup in Fort Collins: what's different here

Fort Collins has many homes with basements and floor drains, which are the lowest point where a blocked lateral backs up first. Roots in older clay lines and grease buildup are the common causes, and heavy spring storms can also stress the system.

After cleanup, a camera inspection finds the cause, and a backwater valve can keep future backups out of the basement. Sewage-contaminated carpet and drywall should be removed, not dried.
