SubSurface LD-8 Leak Survey Tool

Simple and Effective Leak Detection
   

SUBSURFACE LD-8 LEAK SURVEY TOOL

The LD-8 Leak Survey Tool is designed specifically for "water leak surveys" done by water departments, water districts, and other government and private agencies concerned about "unaccounted-for water losses."

The LD-8 is very simple to use, yet it is very sensitive when listening for water leaks at meters, hydrants, and valves. Sounds from water leaks can travel for hundreds of feet (even thousands of feet on iron and steel pipes) on water mains, and a "listen only" leak survey is often very effective at discovering areas with water leaks.
