We have a number of local projects (existing buildings 4 – 6 stories 15 – 20 years old) that survived hurricane Katrina, but in the process of repairing / redoing the properties we have come up with some problems with the existing waste & vent systems.

Existing systems (no-hub cast iron) have an enormous amount of scaling inside them, (both waste & vent) even in the vertical pipe on upper floors. We have found some systems on the 3rd floor completely blocked from the scaling

Systems also have hair line, to ¾” cracks in the piping and fittings, (horizontal and vertical systems) through out the project.

The buildings sat vacant for over 2 ½ plus years, and the waste and vent piping systems may have dried out over that period form not being used.

Our questions:

· Any idea what might have caused:

· Scaleing?

· Cracks?

· Pipe / fitting deterioration?

Would appreciate any information / theory / experience that you might have to share with
