What black pipe are you refering too? Water pressure in schedule 40 pipe exceeds 150 PSI 24/7 365. In hospitals, industrial and high rise buildings, if the pumps are located in the lowest point in the building, they have to overcome the height of the building to get to the highest systems. So the lowest points would have the highest pressure. A 300 ft vertical pipe filled with water would have 129.9 PSI at the bottom while static. And more to push the water higher with a pump. We pipe pneumatic air lines, chilled water, hot water and steam for hospitals and industrial in black pipe since 1919. It depends on the application as to what schedule of pipe that is used.

What ever you do NO PVC, or CPVC PLASTIC.
