The 5-E Electric Smoke Blower from Superior Signal is the leading blower for smoke-testing sewer laterals, residential plumbing, and commercial plumbing lines to locate leaks and sources of sewer gas odors. The 5-E Smoke Blower is designed to work with Superior Classic Smoke Candles and includes a 8ft by 4 inch flexible hose to facilitate delivery of dense, tracer smoke into drain systems and sewer lines. Use the 5E Superior Signal Smoke Blower to deliver dense smoke quickly and efficiently through waste lines, vents and laterals—the entire plumbing tree. The blower produces just the right amount of static pressure to move smoke completely through the piping system without blowing water out of air locks. Insures that every potential odor source is tested--plumbing joints, cuts or cracks in pipes, dry air locks, vents, etc. Find surface water inflow, unwanted connections to downspouts, perimeter drains and yard drains; structural damage, etc. Saves time and money. Contractors and inspectors-- Test new and repaired DWV systems with fast, inexpensive smoke rather than costly, time-consuming water or air pressure tests. Many state and local plumbing codes permit smoke-test-before-acceptance. Applications for the 5-E Smoke Blower: Residential Plumbing; Commercial Plumbing; Sewer and Septic Laterals; Drain-Waste-Vent (DWV) System. 2B Smoke Candles are NOT included in this offer, but are sold separately.
