B. Disassembly of Vent Sections
Securing the Vent Sections
Vertical Sections
Vertical sections of pipe must be supported every 8 feet
after the 25 foot maximum unsupported rise. The vent
support or plumber’s strap (spaced 120° apart) may be
used to do this (see Figure 8.8).
Horizontal Sections
Horizontal sections of vent must be supported every 5 feet
with a vent support or plumber’s strap.
Figure 8.8 Securing Vertical Pipe Sections
To disassemble any two pieces of pipe, rotate either section
(see Figure 8.10), so that the seams on both pipe sections
are aligned (see Figure 8.11). They can then be carefully
pulled apart.
