Recently, I have had quite a few requests to investigate sewer smells, smells from commercial kitchens entering offices and mystery water appearing in building assemblies. I hired a locate drain company to smoke the sewer lines in a complex of buildings and the results were awesome. Some leaks were found right away, others required walls to be opened and and a return trip from the company.
I got to looking at this product which is compact and has a UV dye in the smoke. The potential seems limitless. Sewer smells, HVAC diagnosis, testing vent pipe, blower door work..... http://www.thesmokemachine.com/ezsmoke/product.html
Does anyone have experience with this or similar products? For me, it really needs to be electric, compact and easy to store.
