Richard B. Rennick, who understands the need for efficient, reliable leak detection services, founded American Leak Detection. Growing up, Rennick worked for his father's plumbing company where he had to help locate water leaks in pipes buried under concrete slabs using a 6-pound maul and chisel. Not only was the task tedious and time-consuming, but it left a large mess for the homeowner. It made him realize there had to be a better way to find leaks. As an adult, Rennick became a police officer and supplemented his income with plumbing jobs on the side. While working in the plumbing industry, he grew even more convinced of the need for a less invasive procedure to locate leaks. Rennick decided to team up with an expert to develop equipment, which could locate concealed leaks. After much trial and error, they were able to develop extremely sensitive electronic tools equipped with minute microprocessors. From these humble beginnings, the electronic leak detection industry was born in 1974.
