What to Do First

Whole-home backup symptoms
When several fixtures back up at the same time, the main sewer line is a likely cause. We are preparing to diagnose and clear main-line blockages with clear options before work begins.
Toilets and tubs backing up
A toilet that bubbles when you run a sink, or a tub that backs up, often signals a main-line issue. We are preparing to identify and address these symptoms.
Clearing the main line
Clearing a main-line clog restores flow to the whole home and stops backups. We are preparing to clear main sewer line blockages and explain what we find.
Root intrusion and pipe damage
Tree roots, grease, and pipe damage are common causes of main-line clogs, especially in older neighborhoods. We are preparing to help identify the cause and recommend next steps honestly.
When a sewer camera helps
On select jobs, a sewer camera inspection can help locate roots, breaks, or low spots in the line. A camera inspection may be available when symptoms point to a deeper issue, and it is not part of every job.
What to expect
You'll get a clear explanation of what's happening in the line and your options before work starts. A sewer camera inspection is available on select jobs when it helps pinpoint the cause.

Main line detail
Main Line Problems — A Closer Look
Multiple fixtures backing up
When more than one fixture backs up — especially the lowest ones in the home — the cause is often in the main sewer line shared by the branch drains rather than at a single fixture. Watching which fixtures are affected together helps narrow where the problem sits.
Toilets and tubs backing up together
A toilet and a nearby tub or shower backing up at the same time is a classic main line signal, because they share a common drain path. Water that comes up in a tub when a toilet is flushed is worth taking seriously.
Cleanout access
A main cleanout gives direct access to the main line and makes clearing and inspection more straightforward. Knowing where the cleanout is — or whether the home has one — affects how a main line problem is approached.
When pipe repair or repiping may be needed
Some main line backups come from buildup or roots that can be cleared, while others trace to a damaged or settled pipe, an offset joint, or a belly in the line that holds water. When the pipe itself is the problem, pipe repair or a larger repiping conversation may be the better path. Sewer camera inspections may be available on select jobs when needed to confirm. See our service areas.
