What is Smoke Testing?

Smoke testing is a non-invasive, highly efficient way to identify leaks and faulty connections in your plumbing system, and it has been used in plumbing since 1875. By using high-capacity blowers to blow smoke through the sewer system, our team is forcing smoke into the lines with a controlled amount of non-toxic, visible smoke that leaves no residue, so we can easily watch for signs of cracks, gaps, or faulty seals.

As Santa Cruz's top plumbing team, we are highly experienced at detecting leaks and repairing them – without causing damage to your system. If you think you might have a leak or faulty seal, contact us to set up your plumbing smoke test today.

Our Smoke Testing Process

  • 1

    Preparation 

    Upon arrival at your home, our team will efficiently isolate the section of the plumbing system that we need to test by identifying access points like cleanouts and the building's roof vents before testing begins. This involves closing all the valves, sealing off open pipes, sealing other open vents for effective smoke filling, and ensuring all fixtures and drains are adequately blocked so smoke stays within the system instead of escaping through working sewer line connections.

    Smoke Bombs

    Our plumbing technicians will introduce a controlled, non-toxic smoke source into your system with specialized equipment and, where access requires it, place a blower on top of a manhole to force smoke down into the sanitary sewer and sewer lines. We will also gradually pressurize the system to avoid damaging your pipes.

    Leak Detection

    As smoke escapes from unexpected spots, it helps identify open faults, deficient plumbing connections, and other plumbing issues; the same visual tracing can also help identify improper sources of water entering the sewer system, including sewer inflow or illegal stormwater cross-connections. Once all of the leaks or issues have been identified, our crew will mark locations for repair and isolate them by sealing off or repairing the affected sections.

    Problem Resolution

    After gathering all of the information, the Duncan Plumbing crew will compile a comprehensive report of the testing process, including recommendations for necessary repairs and maintenance. We'll then ventilate the plumbing system to ensure it's clear of smoke and ready for regular use. If any visible smoke indoors appears during testing, smoke dissipates in about 20 to 30 minutes. This also helps confirm the system is working properly before normal use resumes.

The Benefits of Smoke Testing

Precision 

Smoke testing is widely considered the most accurate method for detecting leaks, even those that are tiny or concealed in difficult-to-access spots, and it can also identify deficient plumbing connections or other improper sources that let sewer gas escape.

Non-Invasive

Many homeowners prefer this method of leak detection because it doesn't require us to dig up anything or risk damage to the plumbing system. It's safe, efficient, and harmless. When plumbing is correctly installed and functioning properly, the smoke should vent outside rather than enter your home.

Quick & Cost-Effective  

By precisely identifying leaks, we avoid exploratory work, reduce repair costs, and minimize disruptions. Early testing can catch a faulty sewer lateral before it causes backups or drain runoff on the property, also revealing hidden drain runoff issues before they spread.
