Sewer Backup Services in the Tri Cities Area

Wastewater backing up into sinks, toilets, showers, or floor drains needs immediate attention. Sewage can expose people to harmful bacteria, damage floors and other materials, and make parts of your property unusable. Campbell & Company offers sewer backup services throughout Kennewick, Pasco, Richland, and the surrounding Tri-Cities area. Our plumbers locate the source of the backup, clear the obstruction, and address problems within the sewer line.
What Is a Sewer Backup?
A sewer backup occurs when wastewater cannot continue through the sewer line and begins flowing back toward your home or commercial building. Instead of moving away from the property, sewage can surface through toilets, showers, tubs, sinks, or floor drains.
One slow sink or tub can point to a localized clog. When several fixtures back up at once, the problem can be farther down the drainage or sewer system. Sewage entering the property is a plumbing emergency and needs professional attention.
Common Signs of a Sewer Backup
A backup does not always begin with wastewater spilling from a drain. Changes throughout the plumbing system can warn you that a larger blockage is developing. Signs include:
- Multiple drains backing up at the same time
- Toilets overflowing without an obvious cause
- Water backing up into showers or bathtubs
- Floor drains overflowing
- Gurgling sounds from drains or toilets
- Slow drains throughout the property
- Strong sewage odors indoors or outside
- Wastewater appearing in basement drains
- Standing water around cleanout access points
If several of these problems occur together stop using your plumbing and call us.
Common Causes of Sewer Backups
Sewer lines carry wastewater away from the property every time you use a sink, toilet, shower, washing machine, or other connected fixture. A restriction or damaged section of pipe can interrupt that flow.
Tree roots can enter sewer lines through cracks and loose joints, then continue growing inside the pipe. Grease, wipes, debris, and other materials can also collect inside the line and create a blockage. Older or damaged pipes can crack, shift, or collapse and restrict wastewater flow. Flooding and excess water entering a sewer system can contribute to backups as well.
When the cause is not clear, a sewer inspection allows our plumbers to examine the inside of the line and identify roots, buildup, damaged pipe, and other obstructions.
Our Sewer Backup Services
Campbell & Company responds to sewer problems throughout the Tri-Cities area with services based on the cause and condition of the line. For an emergency sewer backup, our plumbers locate the obstruction and determine what is preventing wastewater from flowing through the sewer line.
Our plumbers can clear blockages caused by grease, debris, waste, and other buildup. Drain cleaning can restore flow when a clog is responsible for the problem.
For tougher buildup, hydro jetting uses high-pressure water to clean material from the inside of the sewer line. Tree roots can also be removed when they have grown into the pipe and restricted wastewater flow.
Clearing a blockage does not correct a broken or collapsed sewer line. If an inspection finds pipe damage, our plumbers can determine what repair is needed. Depending on the location and condition of the sewer line, that work can include trenchless sewer repair or sewer line repair and replacement.
Campbell & Company has local technicians serving communities throughout the Columbia Basin, so you have a nearby team to call when sewage starts backing up.

Keep grease, wipes, paper products, and other debris out of drains and toilets. Address recurring slow drains instead of waiting for a complete blockage. Periodic sewer line inspections and cleaning can also identify buildup, roots, or pipe damage before wastewater backs up into the property.
Stop using toilets, sinks, showers, washing machines, and other plumbing fixtures to limit additional wastewater entering the line. Keep people and pets away from sewage-contaminated areas and contact a plumber to locate and clear the blockage.
Yes. Roots can enter sewer pipes through cracks, joints, and damaged sections of pipe. As the roots grow, they catch waste and debris, restrict flow, and eventually create a blockage that sends wastewater back toward the property.
Hydro jetting can remove grease, sludge, debris, and other buildup from many sewer lines using high-pressure water. The condition of the pipe needs to be considered first because a damaged or collapsed sewer may require repair instead of cleaning.
The time depends on what caused the backup. Clearing an accessible blockage can take less time than repairing a cracked or collapsed sewer line. After locating the problem, our plumbers can explain the work required to restore the sewer system.
