Smoke Testing for Sewer Leaks in Boiling Springs, SC
Good service is worth sharing.
There is nothing like the unexplained smell of sewer gas in the bathroom, basement or yard to put one on edge. Add a soggy spot on the lawn or some odd behavior from your drains, and it is usually a sign of a leak in the waste line, vents or connections that is not immediately apparent. For the many homes in Boiling Springs on older lots with well-established landscaping, the last thing anyone wants to do is start digging. Smoke testing is an effective means of locating such issues without disturbing the property. Pro-Flo Plumbing provides this service for both residential and small commercial clients.

What Is Smoke Testing?
Smoke testing is a straightforward form of leak detection for sewer and drain systems, quite unlike the acoustic approach used on a pressurized water line.
- We seal off part of the drain or sewer line and run harmless, non-toxic smoke through it with a blower.
- If there is a crack, a poor seal, a missing cleanout cap or a vent that has not been connected right, the smoke makes its way out and is plain to see.
- It is a quick, visual matter rather than hours of guessing.
When Smoke Testing Makes Sense
- Persistent sewer odors indoors or outdoors.
- Unexplained wet or sunken areas in the yard near the sewer line.
- Slow drains or repeated backups that keep coming back after cleaning.
- Vent stack problems such as gurgling fixtures or sewer gas smells.
- Home purchase or renovation planning, when you want a clear picture of the drain system.
- Suspected stormwater or groundwater getting into the sewer line.
How the Process Works
Our technician will start by going over the layout and what you have been seeing. We find the cleanouts, plug the openings and, where called for, let the neighbors know so nobody is alarmed by a bit of smoke. From there we walk the grounds to check the foundation, roof vents and other connection points. A leak will be marked and we will tell you what we are looking at. Should the situation call for it, we can put a sewer camera in the line to see if it is a simple fix or something more involved. An hour is all it generally takes, with no digging, no chemicals and no damage to your landscaping.

Local Sewer Rules and Why Leaks Matter
In Spartanburg County the utility is on top of preventing sanitary sewer overflows, but the homeowner is typically on the hook for the lateral from the house to the connection at the main. A crack in that line lets in groundwater and rainwater and allows raw sewage to get out. The state and the plumbing code have their rules for proper venting and sealed cleanouts, and septic systems fall under environmental regulations instead. An early find is good for the yard, for your neighbors and for the streams that supply the region’s drinking water.
Fixing What We Find
Once we have identified the problem with our test, our plumbing repair team is ready to deal with it, be it a resealed cleanout, a new section of pipe, a vent repair or a failing sewer line. We will give you a clear explanation and a fair quote so you can make an informed decision.
Frequently Asked Questions About Smoke Testing
Is smoke testing non-invasive?
Yes. It is a non-invasive way to find undetected problems in the water and sewer system without excavation. You receive detailed reports of any smoke that escapes, and same-day results are common for homes and businesses across the Upstate and surrounding counties.
Can a smoke test find slab leaks or water leaks?
No, smoke testing is for sewer and vent lines. For a water leak, slab leaks, or higher bills, a licensed plumber uses other methods. We can evaluate your plumbing system, explain which inspection makes sense, and provide repair and installation work for the source of the problem, including crawl space and main line issues.
