How do I troubleshoot an air leak with my cyclone?
If you can't audibly pinpoint where the leak might be coming from, one of the simplest ways to check for air leaks is with a smoke test. Kits for this can be found at most local hardware stores (usually near the HVAC sections), but it's simple to make a small DIY version or even use incense sticks at home.
Simply light an incense stick while the system is running and move the stick around the perimeter of the cyclone where it connects to hose, ductwork, or directly to the drum lid. Also move the incense stick around the perimeter of where the drum lid meets the drum, as well as any other connection points in your setup. If at any time you see the incense smoke being drawn into the system, you’ve found an air leak that needs to be sealed. Continue looking for additional leaks, including damaged spots on fiberboard drums, until you’ve exhausted all possibilities.
