The clearest sign of a sewer line problem is more than one drain backing up at the same time, especially water rising in a tub or shower when you flush a toilet. Gurgling drains, sewage odors, repeated main line clogs and wet or sunken spots in the yard are other common warning signs.
1. Multiple drains are slow or backing up
One slow sink is usually a local clog. When the kitchen, bathrooms and laundry all slow down together, the shared main line is the likely problem.
2. Water comes up in the tub or shower
Showers and tubs are often the lowest drains in a home. When the main is blocked, wastewater backs up there first, often when a toilet is flushed or the washer drains.
3. Gurgling toilets and drains
Gurgling happens when air is forced through water traps as wastewater struggles past a blockage. Gurgling in several fixtures points to the main line or venting.
4. Sewage odors
A sewer smell inside the home, around floor drains or near the outdoor cleanout can mean a blockage, a break or a dried-out trap. Persistent odors should be checked.
5. Repeated main line clogs
If a plumber has cleared your main line more than once in a year or two, something is causing it: roots, a sag, corrosion or a broken section.
6. Wet, sunken or extra-green patches in the yard
A leaking sewer line can saturate soil over its path, causing soggy spots, depressions or unusually lush grass.
7. Pests
Broken sewer pipes can give rodents and insects a path into or near the home. An unexplained increase in pests near drains is worth noting.
What causes sewer line damage?
- Tree roots drawn to moisture at pipe joints and cracks
- Corroded cast iron in older homes, which can scale and crack
- Grease and wipes forming stubborn blockages
- Settling soil creating sags (bellies) or offset joints
- Heavy storms that can overwhelm systems and contribute to backups
What a sewer camera inspection shows
A plumber runs a waterproof camera through the line from a cleanout and can see roots, cracks, offsets, sags and blockages, and measure how far along the line each one is. That tells you whether cleaning will solve the problem or whether a spot repair, lining or replacement is needed. It’s also a smart step before buying an older Boca Raton home.
What to do if sewage backs up
- Stop using water in the house: no flushing, showers, laundry or dishwashing.
- Keep people and pets away from contaminated water.
- Call a plumber right away. Sewage backups are treated as emergencies.

Frequently asked questions
How do I know if the problem is my sewer line or just a clogged drain?
A single slow fixture is usually a local clog. Several fixtures backing up together, especially tubs and showers, points to the main sewer line.
How often should a sewer line be inspected?
There’s no fixed schedule. A camera inspection is worth doing if you have repeated clogs, before buying an older home, or after a sewage backup.
Can roots be removed from a sewer line?
Plumbers can cut roots out with specialized cutting heads or jetting, but roots usually return unless the entry point is repaired or the line is lined or replaced.
Who is responsible for the sewer line?
Typically the property owner is responsible for the private lateral from the building to the public connection, but boundaries vary. In condos, shared stacks are usually the association’s responsibility.
