B. Disassembly of Vent Sections
To disassemble any two pieces of pipe, rotate either section
(see Figure 8.11), so that the seams on both pipe sections
are aligned (see Figure 8.12). They can then be carefully
pulled apart.
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 sup-
port or plumber’s strap (spaced 120° apart) may be used
to do this (see Figure 8.9).
Horizontal Sections
Horizontal sections of vent must be supported every 5 feet
with a vent support or plumber’s strap.
