When it comes to productivity and durability, John Stemmle knows a good thing when he sees it. That's why his company, Stemmle Plumbing Repair Inc., in Richmond, Va., owns 17 Duracable DM30 cable drain cleaning machines – one for each of the company's service trucks.
Over the years, the Duracable machines have become an integral part of Stemmle Plumbing's operations, which breaks down into about 65 percent commercial work and the rest residential. The company uses the DM30s – equipped with a 1/2 hp, 200 rpm motor and designed for 2- to 6-inch-diameter lines
