7 Warning Signs Your Sewer Line Needs Repair

By Sewer Line Repair Team · September 2026 · Marlborough, MA

Your sewer line can’t send a text when it’s failing — but it does send signals. Learn to read them and you’ll catch most problems while they’re still a camera inspection and a cleaning, not an excavation.

1. Multiple slow drains at once

One slow sink is a local clog. When the tub, toilet, and washing machine all drain slowly together, the restriction is in the main line they share.

2. Gurgling sounds

Air trapped by a partial blockage bubbles back through fixtures. Toilets gurgling when the washer drains is the classic tell.

3. Sewage odors

A healthy sewer system is sealed. Smells in the yard, basement, or from drains mean a crack or dry trap is letting gas escape.

4. Lush or soggy patches in the yard

Sewage is fertilizer. A suspiciously green strip of grass over the sewer run — especially a soggy one — often marks a leak.

5. Recurring clogs

Clearing the same drain twice a year isn’t maintenance, it’s a symptom. Roots, scale, or a belly keep catching debris in the same spot.

6. Backups in the lowest fixture

The basement floor drain or downstairs tub is the first place a main-line blockage shows itself. If it’s happened once, it will happen again.

7. Foundation cracks or settling near the line

A long-term leak washes soil from under slabs and footings. New settling near the sewer exit deserves a camera look.

Seeing two or more of these? A camera inspection settles the question in under an hour. Call (833) 713-2101 and we’ll take a look inside your line.
