      Have someone bring a camcorder and post it on YouTube. (Immediately before, call FD on non emergency dispatch line and tell them what you are doing and where.)
      Poison smoke?
      We used to make our own smoke bombs.
      I'd take an educated guess - but I'm unqualified.
      It ain't just soot, it's paydirt.

          How long to pump up a typical DWV system to test pressure?
          I normally pump up to around 500 to 1000 KPA before the inspector comes and allow another 5 to 10 minutes whilst he`s there, you don`t have to do much pumping as you are already useing the existing air in the pipe the same way you test a gas pipe.

            We can no longer test with air, period.

            Pipe mfg. state it in their literature that no air test should be done. (PVC & I think CPVC)

              "Night hitch"? Must be proper attire in SFC.

              We ain't never lost a foundation!

                  Smoke test works well on high rises. Finds missed wax seals and loose joints easily. You can build a smoke generator with a 55 gal drum and a shop vac to push the smoke into the stack. Introduce the smoke at the bottom of the stack.

                  shop-vac outlet --->55 gal drum---->test tee at base of stack----> plug top of vent on roof

                  Allow some method of pressure relief; you only need a couple PSI; and don't forget to fill your traps or you will have smoke coming out everywhere.
                  "When we build let us think we build forever. Let it not be for present delight nor for present use alone. Let it be such work that our descendants will thank us for, and let us think, as we lay stone upon stone, that a time is to come when these stones will be held sacred because our hands have touched them, and that men will say, as they look upon the labor and wrought substance of them, "See! This our fathers did for us."
                  John Ruskin (1819 - 1900)

                      Tool
                      How did your smoke test turn out? Did you place the bomb in a stack or at the base of the line? Do you recommend the rodent smoke bombs you used?
                      I've got to do a test next week and I want to get it right the first time. I wonder what kind of smoke grenade Plumberscrack is referring to.

                            Made by Superior Smoke Signal company

                            They have a 30, 60, or 90 second bomb found at most HVAC distributors

                            $6 each for the 60 sec. ones. About 2 out of every dozen are duds so keep a few extra on hand.
