Commercial Drain Cleaning and Clearing in Spartanburg
Drain Cleaning Services For Spartanburg Businesses
A backed-up drain in a commercial building can close a kitchen, take restrooms out of service, or send wastewater into customer and work areas. Even a slow drain can become disruptive when dozens or hundreds of people use the plumbing each day.
CB Smith Plumbing has provided commercial drain cleaning in Spartanburg since 1982. Our licensed plumbers clear blockages, investigate recurring problems, and work around your operating hours whenever possible.
Commercial Drain Cleaning for High-Use Properties
Commercial drain systems often handle heavier and more frequent use than residential plumbing. Multiple fixtures may share the same lines, and restaurants, offices, healthcare facilities, and other busy properties can place significant demands on them.
Common causes of commercial drain problems include:
- Grease and food buildup in kitchen lines
- Paper towels, wipes, and hygiene products in restroom drains
- Debris and sediment in floor drains and mop sinks
- Mineral scale inside older drain lines
- Tree roots entering underground sewer piping
- Sagging, separated, or damaged sections of pipe
Floor Drains, Trench Drains, and Mop Sinks
Floor and trench drains can collect grit, food debris, mop water, and other material throughout the workday. Mop sinks can develop similar buildup with repeated use.
When these drains begin emptying slowly or pooling water, we can clear the obstruction and check for a deeper problem when needed. Floor drains that are rarely used can also develop dry traps, which may allow sewer odors into the building.
Restaurant Drain Cleaning and Grease Lines
Restaurant drain lines handle grease, food particles, detergent, and heavy daily water use. Over time, grease can collect along the inside of the piping and restrict flow.
Commercial dishwashers can contribute to buildup farther down the line. Hot water and detergent may carry grease beyond the immediate kitchen area. As the water cools, grease can collect on the pipe walls and contribute to clogs that develop farther into the drainage system.
Grease Traps, Interceptors, and Drain Lines
Spartanburg Water maintains a grease control program for businesses that discharge fats, oils, and grease. Grease traps and interceptors capture much of that material before it reaches the sewer system.
Pumping or cleaning an interceptor does not necessarily remove buildup from the connected drain lines. When grease accumulates beyond the interceptor, we can use mechanical clearing or hydro jetting to clean the affected piping.

How We Clear Commercial Drain Lines
The right clearing method depends on the location of the blockage, what is causing it, and the condition of the pipe. We assess the affected drains first, clear the line with the appropriate equipment, and verify that flow has been restored.
When recurring backups or other signs point to a larger problem, we may recommend a camera inspection to look inside the line.
Mechanical Drain Clearing
Commercial drain clearing often uses a heavy-duty cable machine with cutting heads designed for different types of blockages. This method works well for many restroom clogs, branch line blockages, and other localized drain problems.
Hydro Jetting Commercial Drain Lines
Hydro jetting uses high-pressure water to remove grease, scale, and other buildup from inside the pipe. It can be especially useful for commercial kitchen lines and other drains with significant accumulation along the pipe walls.
Before jetting older or potentially damaged piping, we may inspect the line with a camera. This helps us determine whether hydro jetting is appropriate for the condition of the pipe.
Camera Inspections for Recurring Drain Problems
A drain camera can help locate blockages and identify problems such as heavy buildup, roots, damaged piping, or sagging sections. In multi-tenant properties, camera footage can also help property managers determine where a problem is located within the drainage system.

What to Do During a Commercial Drain Backup
If wastewater is backing up into a commercial space, reducing water use can help prevent the problem from getting worse while service is on the way.
- Stop using fixtures and equipment that drain into the affected area.
- Close affected restrooms or work areas when necessary.
- Keep employees and customers away from wastewater.
- Avoid using chemical drain cleaners.
- Document visible damage when needed for property or insurance records.
For restaurants, a backup affecting a kitchen or food preparation area may require additional cleaning and sanitation before the space can return to normal use. For problems that cannot wait until regular business hours, our emergency plumbing service is available.
Commercial Drain Clearing Around Your Hours
Drain service in a commercial building needs to account for customers, employees, tenants, and normal operating hours. For non-emergency work, we can often schedule service during slower periods to reduce disruption.
Property managers may also need to coordinate access when shared drain lines run through occupied spaces. We work with you to plan access and keep affected tenants informed.
Accessible cleanouts can make drain service faster, especially during a backup. If cleanouts are hidden behind equipment, landscaping, or other materials, locating and marking them ahead of time can save time when service is needed.

Recurring Commercial Drain and Sewer Problems

A drain that repeatedly clogs may have a problem that clearing alone will not correct. Camera inspection can help identify conditions inside the line that contribute to recurring backups.
Scale in Older Drain Lines
Older cast iron drain lines can develop heavy scale along the interior walls. As the opening narrows and the surface becomes rougher, grease, paper, and other debris can collect more easily.
When scale is contributing to recurring problems, commercial drain line descaling may help remove that buildup and improve flow.
Roots and Damaged Sewer Lines
Tree roots, sagging pipe, separated joints, and other damage can all contribute to recurring sewer backups. If a camera inspection identifies damaged piping, we can explain the repair options and whether the affected section needs additional work.
Not every sewer backup originates inside the building’s plumbing system. A problem can also occur farther downstream in the public sewer system. When our inspection indicates the issue is outside the property’s plumbing, we can explain what we found so you know who to contact next.
Preventive Commercial Drain Cleaning
High-use kitchen, restroom, laundry, and main drain lines may benefit from periodic cleaning when they have a history of recurring buildup. The appropriate schedule depends on the property, how heavily the drains are used, and how quickly buildup returns.
Preventive drain cleaning can also be incorporated into ongoing commercial plumbing maintenance when it makes sense for the building.

Frequently asked questions about drain cleaning in Spartanburg, SC
How do I know if I need professional drain cleaning or if a plunger will do the job? A plunger works on surface-level clogs that are close to the drain opening, typically a small accumulation of hair or debris sitting in the trap. If you have plunged repeatedly and the drain still runs slow, or if it clears temporarily and clogs again within days, the blockage is further down the line and requires professional equipment to clear properly. A plumber will use a drain snake or hydro-jetting to reach and remove the actual source of the problem, not just push it further into the pipe.
Is hydro-jetting safe for the pipes in my Spartanburg home? Hydro-jetting is safe for most residential drain lines in good structural condition, including PVC, ABS, and properly maintained cast iron pipe. Spartanburg has a significant number of older homes with aging cast iron or clay tile drain lines, and in those cases our technicians assess the condition of the pipe before recommending hydro-jetting. If the line shows signs of deterioration, we discuss the right approach with you before applying high-pressure water. The goal is always to clear the blockage without causing additional damage.
Can I use chemical drain cleaners instead of calling a plumber? Store-bought chemical drain cleaners can dissolve minor organic buildup in a drain trap, but they are not effective against grease accumulation deeper in the line, root intrusion, or any blockage caused by a physical object. More importantly, the caustic chemicals in these products react with the interior walls of older pipes and accelerate corrosion over time. In Spartanburg homes with cast iron drain lines, repeated use of chemical cleaners can cause more damage than the clogs they are meant to solve. A professional drain cleaning visit costs more upfront but protects the integrity of your pipes long term.
What causes recurring drain clogs in the same fixture? A drain that clogs repeatedly in the same location is almost always pointing to something the initial clearing did not fully address. Common causes include a partial blockage that was pushed further down rather than removed, grease or soap buildup that has hardened on the pipe walls, root intrusion from nearby trees working its way into the sewer line, or a backpitch in the pipe that causes water and debris to pool in one spot. A camera inspection of the drain line is the most reliable way to identify which of these is the actual cause and determine the correct fix.
How long does drain cleaning take, and do I need to be home? A standard single-fixture drain cleaning appointment typically takes between 45 minutes and an hour. Main sewer line cleaning or hydro-jetting jobs run longer, usually one and a half to two hours. Someone over the age of 18 should be present during the appointment to provide access and to hear the technician’s findings directly. CB Smith technicians explain what they found and what they did before leaving, so being present ensures you have a full picture of your drain line’s condition.
Do you offer emergency drain cleaning in Spartanburg? Yes. When a drain backs up completely or sewage begins returning through floor drains or lower fixtures, that is not a situation that can wait until the next scheduled appointment.
