How to Prevent Sewer Backups
  • Do not pour grease down the drain.
  • Only flush human waste, water, and toilet paper down the commode.
  • Know the location of your clean out cap. The clean out cap is a white plastic cap, usually four inches in diameter, located in your yard close to the house.
  • Tighten the clean out cap to prevent debris from clogging the pipes.
  • Do not plant trees near the pipelines. The roots will grow into the pipes causing a backup.
  • Get a pop-off valve to minimize damage. A pop-off valve opens automatically to relieve the line if there is a backup. They are inexpensive and easy to install. Contact your local plumbing supplier.
