Rennick must have found his better mousetrap because last year American Leak Detection reported $21 million in systemwide sales.
Back when Dick Rennick was starting out in his father’s Riverside, CA, plumbing business, his dad routinely handed him a “leak detection kit” — a sledgehammer and chisel.
“He’d just tell me, ‘Go find the leak,’” Rennick says. “A couple of hours later my knuckles were raw and my hands were bloody. Sometimes I found the leak, sometimes I didn’t. I figured there had to be a better way.”
