The 5E Electric Smoker from Superior Signal Co. is designed to connect to any clean-out or inspection port to smoke test an entire system in a few minutes. Smoke testing can be an effective technique for finding the sources of odors and many other faults throughout a building’s plumbing, laterals, the septic system and leachfield. The unit gently pushes smoke throughout the system to find cracks and leaks and quickly identify problems. The unit sets up and shows results quickly, and it comes with an 8-foot industrial-grade flex hose. 800/945-8378; www.superiorsignal.com.
