Vent Pipe Preparation and Joining

Most failures in vent systems result from improper preparation and joining
of pipe and fittings. The guidelines below must be follow ed w hen installing
the venting system. If you have any question about the application or
installation of the venting system, contact the vent pipe manufacturer,
supplier, or your plumbing professional.
1) Specific cleaners, solvents, primers and cements are available for PVC,
CPVC, and ABS pipe. Be sure these materials match the type of pipe to
be installed. The vent pipe manufacturers joining instructions must be
follow ed in all cases. Never use all-purpose cements, commercial glues
and adhesives or ABS cement to join PVC or CPVC pipe and fittings.
Refer to the table at the beginning of the '' Venting'' section for
approved primers and cements.
a) CLEANERS, SOLVENTS, PRIMERS AND CEMENTS ARE
FLAMMABLE. Do not store or use these materials near heat or
open flame, or in the vicinity of other appliances.
2) Use proper cutting, deburring and applicator tools to ensure proper
preparation and joining of pipe and fittings.
a) Cutting Tools
i) A square cut must be achieved w ith a miter box saw or pipe
cutter to ensure a proper mating w ith the female. If a pipe
cutter is used, the burr created at the outer edge of the pipe
must be removed.
b) Deburring Tools
i) A file, knife or plastic deburring tool can be used to remove
burrs. Burrs must be removed from the inside and outside
edges of the pipe to ensure a proper seal.
c) Applicator Tools
i) A natural bristle paintbrush or roller may be used to apply
cement. Prompt application of the cement is important due its
fast drying properties.
3) Inspection, Cleaning, Priming and Cementing
a) Inspect the pipe inside and out for dirt, dust, moisture or grease
etc. Check pipe and fittings for splits or cracks and replace if
found.
b) Clean pipe and fittings are imperative for proper joining. Follow ing
cutting and deburring, w ipe aw ay any foreign material w ith a clean
dry rag. If w iping fails to thoroughly clean surfaces, chemical
cleaning is necessary.
c) Primer must be applied to the pipe surface and fitting socket w ith a
natural bristle brush. This serves to soften and prepare the pipe for
cementing.
