The 5E Electric Smoker from Superior Signal offers a cost-effective solution to find difficult leaks and odors in residential and commercial plumbing systems. Connect the blower to any plumbing clean-out or vent, or to the septic tank, and use an appropriately sized smoke candle to force smoke through faults and cracks to identify the sources of odor and hard-to-find leaks. It handles all residential and commercial smoke testing applications using smoke candles from 30 seconds to three minutes. The unit comes with an 8-foot industrial-grade flex-hose, weighs just 8 pounds, and requires no maintenance. 800/945-8378; www.superiorsignal.com BOOTH #4110
