The 5E Electric Smoker from Superior Signal Company offers a cost-effective solution to find difficult leaks and odors in residential and commercial plumbing systems. It can be connected to any plumbing clean-out or vent, using appropriate-sized smoke candles to force smoke through faults and cracks, easily identifying sources of odor and hard-to-find leaks. Smoke tests take just minutes to perform. A 1A or 2B Superior Smoke Candle creates 4,000 or 8,000 cubic feet of smoke. Candles are sold in convenient SealPac cans, which extend shelf life. Smoke testing can help find odors and many other faults throughout building plumbing, septic systems and even leachfields. The unit comes with an 8-foot industrial-grade flex-hose, weighs just 8 pounds and requires no maintenance. 800/945-8378; superiorsignal.com.
