At Texas Plumbing & Drain, we specialize in sewer smoke testing across the DFW Metroplex. A smoke test is one of the fastest ways to find hidden cracks, breaks, and leaks in your sewer line — without tearing up your yard or property. Our licensed team pumps a safe, non-toxic smoke into the sewer system and watches where it escapes, pinpointing problems quickly and accurately. Whether it’s a residential home, multi-unit property, or commercial building, we find the issue fast and give you a clear plan to fix it.
