This is a smoke test we performed at a 14 unit condo development in Fort. Lauderdale Florida today. We found smoke in 9 of the 14 units in the building of a total of 16 different problems. Once all the repairs have been made we will perform another smoke test to make sure all leaks have been found. 5 plumbers have been on site and performed numerous smoke tests using smoke bombs during the last year. Nothing works like liquid smoke, and this is another example of that fact.
