A sewer backup is one of the most unpleasant problems a homeowner can face. When wastewater starts coming up through a floor drain, shower, toilet, or other low fixture, the first goal is to stop adding more water to the system and figure out where the blockage may be.
Stop using water in the house
Do not flush toilets, run sinks, take showers, use the washing machine, or operate the dishwasher. Every gallon sent into the plumbing can add to the backup until the blockage is cleared.
Keep people away from contaminated water
Sewage can contain bacteria and other contaminants. Keep children and pets away from the affected area and avoid direct contact with wastewater. If electrical equipment or outlets are near standing water, do not enter the area until it is safe to do so.
Look at the pattern of the problem
If one sink or tub is slow, the clog may be local to that fixture. If several fixtures are affected at once, especially the lowest drains in the home, the problem may be farther downstream in the building sewer or public system.
Your cleanout can help a plumber diagnose the problem
A sewer cleanout provides access to the building sewer without removing a toilet or opening walls. If you know where yours is located, make sure it is accessible. Do not remove a cleanout cap if sewage is under pressure unless you know what you are doing. Learn more in What Is a Sewer Cleanout?
Call the right people
A licensed plumber can inspect and clear problems in private plumbing and the building sewer. If there is reason to believe the issue involves the public sewer main, contact the Ben Davis Conservancy District as well. We can help determine whether the public system needs to be checked.
After the flow is restored
Ask why the blockage happened. Roots, damaged pipe, grease, wipes, offset joints, or a collapsed section can cause repeat backups if the underlying issue is not addressed. A sewer camera inspection may be recommended when problems recur.
A backup is an emergency, but a few disciplined first steps can limit damage and help get the right diagnosis faster.
