How We Find the Leaks You Can’t See – Expert Leak Detection by SewerTV Hydro Jetting and Plumbing

Some plumbing problems make themselves known with a bang. Others creep in slowly—silently damaging your walls, floors, foundation, and wallet. At SewerTV Hydro Jetting and Plumbing, we specialize in leak detection that gets to the root of the problem before it turns into a costly nightmare. If something doesn’t seem right with your water usage or you’ve spotted signs of moisture where it shouldn’t be, here’s why it might be time to call in the pros.

The Hidden Danger of Undetected Leaks

Not all leaks are dramatic. Some take weeks or months to show obvious signs, but in that time, they’re quietly rotting drywall, damaging wood framing, and breeding mold behind the scenes. Leaks under slabs or behind walls are especially sneaky—you might not realize there’s a problem until your water bill spikes or your flooring starts to buckle.

In a city like San Antonio, where many homes have slab foundations and older pipes, leak detection isn’t a luxury—it’s a necessity.

How SewerTV Hydro Jetting and Plumbing Finds Leaks Fast (Without Tearing Up Your Home)

Forget the days of guessing and tearing open walls “just to see.” At SewerTV, we use advanced technology to find the exact source of the leak without unnecessary demolition.

Here’s what’s in our toolkit:

  • Acoustic Listening Devices: These pick up the sound of water escaping from pressurized pipes, even through concrete or drywall.
  • Thermal Imaging Cameras: Great for spotting temperature differences caused by leaks hidden behind walls or under floors.
  • Tracer Gas Detection: We inject a safe, odorless gas into your lines. If there’s a leak, it escapes and is picked up by sensitive detectors.
  • Moisture Meters: Help us measure how deep water has seeped into materials like wood, drywall, or flooring.
  • Video Pipe Inspection: For sewer or drain leaks, we send a high-def camera down the line to visually confirm the damage and its location.

This multi-layered approach ensures we find the leak quickly, accurately, and with as little disruption to your home as possible.


Signs You Might Have a Hidden Leak

Don’t wait for water to come pouring out of your ceiling. Call us if you notice any of these signs:

  • Unexplained spikes in your water bill
  • The sound of running water when no fixtures are in use
  • Damp, soft, or discolored drywall or flooring
  • Mold or mildew odors
  • Warm spots on the floor (could indicate a slab leak)
  • Low water pressure in certain parts of the home

Even small leaks can waste thousands of gallons of water per year and lead to major structural damage if left untreated.
