10. Secure the sleeve at the back end of the packer
with tape, similar to the front. Wrap the tape around
the metal end of the packer, down over the curve of
the end of the packer. Wrapping the tape down over
the curve of the packer end is important for proper
retention of the sleeve in place. See Figure 17 .

The Packer
11. Roll the sleeve back to allow access to the air push
rod connection and pull rope tie off point. Securely
connect a single air push rod (or the air hose) and
tape the connection. Securely connect the pull rope
(see Figure 10). Roll the sleeve down the length of
the rod and rope and securely tape the end of the
sleeve. See Figure 18.

Packer Test Insertion

The packer test insertion ensures that the packer and
equipment can navigate the pipe to the damaged section
in the required time and be retrieved without damage.

This increases the likelihood of a successful patch. Do
not attempt to install the patch without first doing a test
insertion. Consider the additional thickness that the con-
tainment/patch will add to the packer during patching and
whether that will prevent proper insertion of the patch. If
you cannot place the packer in the required time during
the test insertion, do not attempt to patch the pipe.
This is general guidance on packer insertion. Every job-
site is different and requires the skill and good judgment
of the installer to choose proper methods and practices.
For instance, a second access point on the other side of
the patch may be required. This allows an additional pull
rope to be fed through the pipe and attached to the front
of the packer to help pull the packer into place.

ENSURE PACKER CAN BE NAVIGATED TO THE PATCH LOCATION BY
PERFORMING A TEST INSERTION
1. Make sure that the correct packer is properly pre-
pared, including the installation of a packer sleeve.
Containment is not typically needed for test insertion.
2. The packer sleeve can be lubricated with a small
amount of oil soap to simulate the lubricity of the
resin on the packer. The optional accessory ball and
spring guide can be used in place of the packer ball
for improved navigation.
3. Carefully insert the packer into the pipe system.
Monitor the amount of time it takes to insert the
packer.
4 Insert packer so that the distance mark on the air
push rod or air hose is near the same point at the
pipe entrance. Determine if it will be possible to
navigate the packer and the patch to the patch site
before the patch resin hardens. DO NOT INFLATE
packer during test insertion. Installing the patch is
time sensitive and if it is difficult or takes too much
time, it can cause the patching process to not work.
5 Reinspect the drain with camera. Confirm that the
packer is in the correct spot to apply the pipe patch.
6. Using the pull rope, retrieve the packer from the pipe
system. Do not pull on the air push rods, this can
damage the air push rods.
7 . Remove the used packer sleeve from the packer.
Remove the air push rod or air hose assembly from
the packer.
