<VV> pvc/pressure

[Bonnzz at aol.com]

hey gang,
I install acoustical (drop) ceilings in commercial bldgs in south Florida. 
For over 10 years  many condos are adding sprinkler systems to meet current fire 
codes. Many use an orange pvc  (normaly 2-2.5 inches in diameter) which they 
test with nitrogen gas under very high pressure. I think the water pressure is 
around 100 lbs or more when activated.
