Smoke testing is one of the most accurate, non-invasive methods for locating leaks. Technicians force a non-toxic smoke vapor into the sanitary sewer line. This method finds faulty connections to the clean sewer line, allowing storm/surface water infiltration. Leaks releasing flammable methane and hydrogen sulfide can penetrate homes and businesses, causing damage.
Setting Up the Smoke Machine
Simply, a smoke machine works by heating a special fluid and releasing it. This fluid is usually made of a water-based mixture of pharmaceutical-grade glycol and water, although some manufacturers use dry ice or liquid nitrogen instead. A blower then moves the fluid through a series of tubes, which creates a cloud of dense, pleasant-smelling, non-toxic smoke. The smoke can be blown down into maintenance holes, vents and drains to show plumbing professionals where a leak is coming from.
When using a sewer smoke machine, the manufacturer will tell you that it’s important only to use the specific type of fluid that comes with it. Using other types can invalidate the warranty and possibly cause the machine to break down. They will also give you instructions for cleaning the machine after use. Some suggest using a liter of water and white vinegar after 40 hours. It helps remove any carbon – a natural by-product of heating smoke fluid.
Detecting Leaks and Blockages
Sewer smoke testing is a non-invasive method of finding leaks, blockages, and pipe defects. It involves pumping non-toxic, odorless smoke into the drain and sewer pipes, where it escapes through any cracks or gaps. It helps plumbers pinpoint the location and extent of the problem so that they can make accurate repairs quickly and efficiently. A clogged sewer line is more than just an inconvenience for property owners: it can cause foul smells and waste to back up into the home or business and even lead to flooding and sewage contamination. Regretfully, pinpointing the origin of a sewer issue can be challenging unless the pipeline is completely dug up and examined. One of the best ways to find the source of a sewer leak or smell is by conducting a sewer smoke test. Using a smoke machine, professionals can send non-toxic smoke into the pipes and watch for any areas where it escapes.
Smoke Testing
Smoke testing is a non-invasive method of inspecting sanitary sewer lines. By forcing smoke into a line, plumbing professionals can identify any breaks, cracks or other defects that would allow sewer gas to escape into homes. It will enable preventative maintenance before a major issue arises that could be expensive to repair. Field crews push large volumes of smoke mixed with air into the sanitary sewer line during a smoke test, usually through a utility hole. The smoke finds inflow points that permit surface water infiltration into the clean sewer system quickly because it follows the path of least resistance. It includes broken maintenance holes, illegal connections, roof drains, basement sump pumps, and uncapped lateral lines.
The smoke produced is odorless and similar to what a fog machine might be used for entertainment, so it’s safe for home use. The smoke is also 100% predictable, so plumbers can locate a problem without tearing apart walls or ruining landscaping.
Cleaning Up After the Test
When a sewage leak causes the foul smell of rotting household waste and bacteria to seep into your home, you must call plumbing professionals as soon as possible. It is also vital that you find the source of the odor, which can be difficult to do.
Using a sewer smoke test, plumbing professionals can find and pinpoint the location of a pipe leak or break. The non-toxic smoke will penetrate through cracks, holes, and other defects in the pipes, allowing plumbers to locate the exact area where the problem exists.
