Deburring
Use a knife, plastic pipe deburring tool, or
file to remove burrs from the end of small
diameter pipe. Be sure to remove all burrs
from around the inside as well as the outside
of the pipe. A slight chamfer (bevel) of about
10°-15 ° should be added to the end to permit
easier insertion of the pipe into the end of the
fitting. Failure to chamfer the edge of the pipe
may remove cement from the fitting socket,
causing the joint to leak.

Test dry fit of the joint
Tapered fitting sockets are designed so that
an interfaced fit should occur when the pipe
is inserted about 1/3 to 2/3 of the way into
the socket. Occasionally, when pipe fitting
dimensions are at the tolerance extremes,
it will be possible to fully insert dry pipe to
the bottom of the fitting socket. When this
happens, a sufficient quantity of cement must
be applied to the joint to fill the gap between
the pipe and fitting. The gap must be filled to
obtain a strong, leak-free joint.
Inspection, cleaning, priming
Visually inspect the inside of the pipe and
fitting sockets and remove all dirt, grease or
moisture with a clean dry rag. If wiping fails to
clean the surfaces, a chemical cleaner must
be used. Check for possible damage such as
splits or cracks and replace if necessary.
Depth-of-entry
Marking the depth of entry is a way to check
if the pipe has reached the bottom of the
fitting socket in Step F. Measure the fitting
depth and mark this distance on the pipe
O.D. You may want to add several inches to
the distance and make a second mark as the
primer and cement will most likely destroy
your first one.
Apply primer to the surface of the pipe and
fitting socket with a natural bristle brush.
This process softens and prepares the PVC
or CPVC for the solvent cementing step.
Move quickly and without hesitation to the
cementing procedure while the surfaces are
still wet with primer.
