Water leak locators use specially designed sensors that listen for the gurgling or hammering of a cracked pipe below ground. A ground sensor locates through hard surfaces like concrete, asphalt, and tile. A probe sensor picks up leaks through soft surfaces such as grass or carpet, or it can be used as a contact probe on above ground pipes or hydrants. Both should have shock-resistant housings to reduce unwanted noise.
Key Takeaways:
- Water leak locators use specially designed sensors that listen for the gurgling or hammering of a cracked pipe below ground.
- If you are new to leak location, you must learn the sound of a leak before you start your search.
- If you don’t see any obvious evidence of a major water leak, like “ponding” or loud leak sounds, then start a water leak survey.
