Below are a few questions from your upcoming PSI state exam:
(1) How many DFUs are permitted to be added to an apartment building with an existing 1,200 DFUs already installed? Assume the building drainage piping is 8-inch diameter at slope of 1/8″ per foot?
- IPC – TABLE 710.1(1) Row for DIAMETER OF PIPE (inches) “8 inches”, Column for DIAMETER OF PIPE (inches) 1/8-inch Slope per foot lists “1,600” DFUs. Therefore, subtract; Allowable = 1,600 – 1,200 DFUs = 400 DFUs
