Elevation adjustments on the pipe hanger should be made at which point?

• A. Point B
• B. Point C
• C. Point D
• D. Point A

Answer: (D)

Elevation should be set at the hanger that directly supports the pipe. This point fixes the vertical position of the pipe run without altering its path or the positions of other supports. Adjusting here keeps the line true and allows you to establish the proper slope between supports after elevations are set. If you tried to adjust somewhere else along the run, it could change the pipe height in a way that propagates along the span or disrupts alignment with fittings and hangers. So, make the elevation change at the hanger’s connection that bears the pipe.
