HOUSE CONNECTIONS
It is not absolutely necessary to have the house line blocked off from the main, but doing so will increase test efficiency. In most cases there is a cleanout opening through which a plug or balloon can be inserted between the opening and the main, and then inflated. A length of windshield hose or similar type tubing can be attatched to the balloon to facilitate inflation. Vents can be partially blocked allowing the air/smoke mixture to flow through the plumbing system.
Connect the blower to the line and start introducing the smoke through the intake side. NOTE: A properly sized blower is important. Use of a blower with lesser capacity will not generate sufficient pressure to disclose all faults in a line and a blower with too great a capacity may blow water from traps.
Check the interior of the house for smoke. Any smoke should be quickly ventilated by opening doors and windows. Notations should be made of leak locations. Next the yard should be checked for smoke and the location of any smoke marked for later correction of faults.
Smoke will leave no visible residue to damage interior of buildings. It is irritating to breathe, but any irritation will quickly disappear once exposure has ceased. Of course special precautions should be taken with persons having respiratory problems of any kind.
All buildings connected to the lines being tested should be checked for smoke. If a concentration of smoke is present, occupants should be evacuated and the building ventilated. If unvented, smoke will settle out of the air without leaving residue.
