Sewer Backup At Home? Do This First

A sewer backup is one of the more stressful plumbing emergencies a homeowner can face — but staying calm and taking the right first steps can make a real difference in how much damage it causes.

1. Stop Using Water Immediately

Turn off faucets, avoid flushing toilets, and hold off on running the dishwasher or washing machine. Every drop you send down the drain has nowhere to go and can make the backup worse.

2. Locate The Main Shutoff If Needed

If water is actively backing up into a fixture, shutting off the main water supply can help slow things down while you wait for help.

3. Keep People And Pets Away From The Area

Sewage backup carries health risks. Keep kids and pets away from any affected area until it's been cleaned and disinfected.

4. Don't Try To Snake It Yourself If It's A Main Line Issue

A backup affecting multiple drains at once is usually a main line problem, not a single clogged pipe. Store-bought drain snakes and chemical cleaners typically won't fix — and can sometimes worsen — a main line blockage.

5. Call For A Camera Inspection

Once the immediate mess is handled, a sewer scope inspection will show exactly what caused the backup — roots, a collapsed pipe, or a buildup — so it gets fixed at the source instead of coming back in a few months.
