The 5E Electric Smoker from Superior Signal can help find difficult leaks and odors in residential and commercial plumbing systems. It can be connected to any plumbing clean-out or vent, and the appropriate-sized smoke candle forces smoke through faults and cracks, easily identifying sources of odor and hard-to-find leaks. It can handle all residential and commercial smoke testing applications, using Superior Smoke Candles from 30 seconds to three minutes. Smoke tests take minutes to perform, with immediate results. It comes with an 8-foot industrial-grade flex hose that weighs 8 pounds and requires no maintenance. 800/945-8378; www.superiorsignal.com.
