Preventing sewer backups primarily involves proactive measures and protective installations.
Install Protective Plumbing Devices
The most effective way to help prevent a backup is through the installation of specific plumbing devices. The best way to help prevent a backup is to have a plumber install backflow valves or standpipes in all basement or lower level drains to prevent sewage from backing up.
- Backflow Valves: These are one-way valves installed on sewer lines. They allow sewage to flow out but automatically close if flow is detected coming back into the house from the municipal sewer system.
- Standpipes: These are vertical pipes inserted into floor drains. They raise the effective drain level above the potential backup height, containing water within the pipe until the main sewer level drops.
Address Common Causes of Backups
While protective devices are crucial, minimizing the risk at the source is also key.
Common Causes & Prevention:
| Cause | Prevention Strategy |
|---|---|
| Grease Buildup | Never pour grease, fats, or oils down drains. Scrape them into a trash can. |
| Flushing Improper Items | Only flush human waste and toilet paper. Avoid flushing wet wipes, paper towels, feminine hygiene products, etc. |
| Tree Roots | Be aware of tree locations near your sewer line. Consider professional root removal or pipe liners if roots are an issue. |
| Structural Defects | Address cracked, collapsed, or broken pipes promptly through repair or replacement. |
| Heavy Rainfall/Flooding | Ensure proper lot grading away from your house and check basement drainage systems. |
Practice Smart Drain Usage
Simple habits can significantly reduce the likelihood of blockages leading to backups.
- Use drain strainers in sinks and showers to catch hair and debris.
- Avoid using harsh chemical drain cleaners, which can damage pipes over time.
- Consider occasional professional drain cleaning to remove buildup.
By combining professional installation of protective devices with careful household habits, you can significantly reduce the risk of a sewer backup in your home.
