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