Most clogs are minor, but some point to a blockage in the main sewer line that needs fast attention. Knowing the difference helps you respond appropriately.
Likely a Minor Clog
- One sink, tub, or toilet is slow or blocked.
- Other fixtures drain normally.
- Plunging or a basic drain snake clears it.
Signs of an Emergency
- Multiple fixtures back up at the same time.
- Water or sewage rises in a floor drain, shower, or tub when you flush or run a washer.
- Gurgling sounds from drains throughout the house.
- Strong sewage odors in the home or basement.
Avoid Chemical Drain Cleaners
Harsh chemical cleaners can damage pipes and are hazardous to plumbers who later open the line. Stop using water and call for help if you suspect a main line blockage.
What to Do
Limit water use, keep people and pets out of affected areas, and call a provider. They can use cameras and drain equipment to find and clear the blockage.
