Initiate Smoke Test and Inject Smoke

What happens here

The smoke emitter is lit, producing thick white smoke. It is then inserted into the blower hose of the Milwaukee shop vac. The shop vac is activated, and the smoke is visibly forced down the open plumbing vent pipe on the roof. This action pressurizes the plumbing system with smoke, allowing it to escape through any leaks and become visible.

Goal: Introduce smoke into the plumbing vent system to detect any leaks causing the sewer smell.
