Jerry, Yes, it is 0.5 to 1.0 pascals negative pressure as the max.
That is why the 2003 and 2006 code has the special inspections programs, but the big crack is that the installers do not include all the components of a drainage system, and since drainage systems do not require inspections, too often get sloppy work, untrained installers, GC that do not care and then once a leak is detected, the manufacturer is not responsible since their warranty is only for product failure, not workmanship. If for example Tyvek is contacted early on, they have a program for a 10 year warranty for water intrusion, but then again, all components of the system have to be in place.
