Septic system is backing up in Boston
Use this guide to note what’s happening, avoid unsafe checks, and decide when to contact a septic professional.
Quick answer
If wastewater is backing up indoors, avoid using the affected fixtures and keep people and pets away from it. Note which drains or fixtures are affected and when the problem began. Don’t open a septic tank or dismantle plumbing.
What the symptoms may indicate
A problem at one fixture may involve a local drain blockage. Slow drains or backups at several fixtures could point to a broader drain-line or septic-system problem. These patterns can’t confirm the cause. Safely note whether one or several fixtures are affected, and whether you see wastewater or notice unusual odors.
When to call a professional
Contact a septic professional if wastewater is coming back into the home, several fixtures are affected, or the backup returns. Keep away from wastewater, and don’t enter a crawlspace or other unsafe area to investigate. A qualified professional can inspect the system and determine the cause.
