Here's what plumbers are saying about smoke testing:
"It's so easy to learn to do. I had no experience, but I picked it up in a day and mastered it in about a week."
"I found a dry floor drain, covered with vinyl tile, beneath a freezer that was giving off foul odors."
"It's less expensive than a sewer camera, and often gives a quicker, more reliable diagnosis."
"My competition gives me referrals now."
"With smoke testing I knew it was a bad wax ring on the commode in 5 minutes without guessing."
"Customer complained of sewer smell in house. We smoke tested and found a dry trap and a cracked vent stack in the wall."
"I made back my investment the first day."
Smoke testing will diagnose tricky odor problems, find dry traps, bad plumbing connections, cracks/holes in pipes, and show direction odors travel out of roof vents. Simply find an exterior clean-out to attach the smoke blower to. Blower may also be used through roof vents or other access if necessary.
WARNING: Sewer gas can be explosive, and it is not advised to place smoke pellets or candles directly into sewer pipes, but should be used with Superior Signal #5-E Smoke Blower.
