Preventing Sewage Backups

What Can I Do to Prevent Backups?

To protect your property follow these simple Do's and Don'ts.


  • Put diapers or sanitary napkins in the toilet.
  • Dispose of grease down the kitchen drain.
  • Plant trees near sewer lines.
  • Connect any drains or sump pumps to the sewer system.


  • Hire a registered plumber to install a backwater valve (plumbing code requires this) on the lowest drain line.
  • Regularly inspect and maintain the valve.

And, Just in Case...

  • Locate and keep accessible the sewer cleanout in your front yard. If you do not have a cleanout, have one installed by a registered plumber. The cleanout is the property owner's responsibility.
  • Check your homeowners insurance policy. If you are not covered for back-ups, call your agent for information on costs and coverage options.
  • If you experience a back-up, save all receipts related to any repair, cleaning or damages.
