Sewer and drain smoke testing for leak detection or sources of odor is a plumbing method where smoke is sent through your drain pipes and sewage systems. This smoke then travels throughout those pipes and wherever there are cracks or issues in these pipes, smoke will spew out. This non-invasive, inexpensive method reveals issues in your plumbing where there can be leaks, cracks, loose fittings, and other plumbing issues.

When to Schedule Sewer Smoke Testing

Knowing when to schedule sewer smoke testing can make all the difference in preventing long-term sewer problems.

While routine testing is recommended, specific signs indicate that immediate testing may be beneficial:

  • Persistent Sewer Odors: Unpleasant smells in or around your property can indicate leaks or other issues in the sewer system.
  • Unexplained Sewer Backups: If you’re experiencing frequent backups, smoke testing can identify hidden causes like blockages or damaged pipes.
  • Visible Surface Water Near Sewer Lines: Standing water or excessive dampness around sewer lines may indicate a leak that needs attention.
  • History of Sewer Issues: Properties with past sewer problems can benefit from smoke testing to ensure no residual issues remain.
  • During Property Transfers: If you’re buying or selling a property, smoke testing can help verify the condition of the sewer system, providing valuable peace of mind.

Proactive smoke testing can protect your property and help avoid unexpected repair costs.

Benefits of Sewer Smoke Testing

Why Invest in Sewer Smoke Testing?
Sewer smoke testing offers a proactive approach to maintaining a healthy and efficient sewer system. By detecting issues early, you can prevent small problems from turning into costly repairs, safeguard public health, and contribute to a more sustainable environment. Here’s why sewer smoke testing is a valuable service:

  • Cost-Effective Maintenance: Identifying minor issues before they escalate saves you money on repairs and prevents potential disruptions.
  • Reduces Health Risks: Smoke testing helps detect leaks that could allow sewage gases to enter properties, reducing health risks for residents and employees.
  • Prevents Groundwater Contamination: By locating cracks or unauthorized connections, smoke testing helps keep contaminants out of groundwater, promoting a cleaner environment.
  • Minimizes Surface Water Infiltration: Pinpointing and repairing entry points for rainwater prevents excess strain on sewer systems during storms.
  • Improves Property Value: A properly maintained sewer system boosts the value of any property, as buyers and tenants recognize the long-term benefits of a functional and safe sewer infrastructure.

By investing in sewer smoke testing now, you can prevent costly issues later and ensure a safer environment for everyone.

How Does Smoke Testing Work?

A harmless, non-toxic smoke is pushed through the plumbing system with just enough force to overcome atmospheric pressure. This allows the smoke to then escape from any crack, break, or other openings in your system. The test doesn’t take long to conduct and is less labor-intensive than other available methods. Plumbers look for smoke exiting in unexpected locations to identify the source of your problem.

Common Issues Detected by Smoke Testing

What Problems Can Sewer Smoke Testing Identify?
Sewer smoke testing is highly effective at detecting a wide range of issues in sewer and drainage systems. These common issues, if left unresolved, can lead to costly repairs, health hazards, and environmental damage. Below are some of the key problems that smoke testing can help identify:

  • Cracked or Damaged Pipes: Aging infrastructure or external damage can lead to pipe cracks, which allow contaminants to leak into the surrounding soil and water.
  • Illegal Drain Connections: Unauthorized connections divert storm water or other waste into the sewer system, potentially overloading it and causing backups.
  • Manhole Defects: Manholes with damaged seals or cracks can allow excess water to enter sewer lines, causing strain on the system.
  • Leaky Sewer Joints: Smoke can reveal spots where sewer pipes have misaligned or shifted, allowing leaks that could disrupt the entire system.
  • Root Intrusions: Tree roots may invade sewer lines through small cracks, eventually growing larger and causing significant blockages and damage.

How Long Does It Take To Perform Sewer Smoke Testing?

The time it takes to conduct a proper smoke test can range anywhere from 1 hour to 3 hours, depending on the complexities of the plumbing system. This could include how large the drain system is, how many stories, the accessibility of the plumbing, or how long the breach is.
