Pipe Patch

ONCE RESIN IS CURED, DEPRESSURIZE THE PACKER
10. Remove the air hose connection and pressure regu-
lator from the air push rod.
11. Using the pull rope, retrieve the packer assembly from
the pipe system. Do not pull the packer assembly with
the air push rods. The air push rods are designed for
pushing the packer into place and delivering air into
the packer. They are not designed to be used as the
primary method of extracting the packer and could
break if exposed to undue force.
12. Check the pipe patch with the camera. See Figure 7-8.

REMOVE THE PACKER
13. Remove the air push rod sections, pull rope and
leader guide from the packer.
14 Clean up the area. Allow excess resin to dry on table
covering and dispose.
Installing Multiple Patches
If the damaged area is longer than one patch, or if there
are multiple damaged areas, it is acceptable to install mul-
tiple patches. When installing multiple patches, generally
start with the patch that is the furthest down the line and
work back to the access point. Once the first patch has
reached its resin set time, the next patch can be started.
Patches can be overlapped as necessary - be aware of
the additional reduction in diameter from overlapping
patches.
Storage
WARNING
Disassemble the air push rod sections.
Make sure the equipment is clean. Wrap the air hose and
pull ropes. Store the packer and equipment in carry case,
or store straight and flat. Do not place anything on the
packer – this can damage the packer and cause leaks.
The equipment must be kept dry and indoors or well
covered if kept outdoors. Store the equipment in a locked
20
area that is out of reach of children and people unfamiliar
with pipe patching system. This equipment can cause
serious injury in the hands of untrained users.
Maintenance Instructions
WARNING
The pipe patching system must not be connected
to any air connection before any maintenance.
Always wear safety glasses and other appropriate
protective equipment when performing any main-
tenance.
Cleaning
After each use, clean the packer, air push rods and other
connections with a damp, soft cloth. A mild detergent or
antibacterial solution can be used if desired. Do not use
solvents, abrasives or other harsh cleaning agents. Do
not let anything into the air connections. Dirt, liquids, etc.
in the air system can damage the regulator and packer
and prevent proper operation.
Wipe off the dried resin using a paper towel.
Once the packer is clean, apply baby powder to the black
rubber portions of the packer. This will help protect the
rubber and allow sliding between the packer and the
packer coverings during use.
Check air connections/threads, clean as necessary.
Packer Testing
Test the packer to check for leaks and for proper inflation.
Do not test packer outside of properly sized pipe to avoid
equipment damage and burst hazard..
1. Install a packer sleeve on the packer.
2. Take a straight length of pipe matching the packer
diameter rating and at least one foot longer than the
packer. Make sure that pipe inside is clean and free
from debris.
3. Install a single air push rod to the packer. Insert the
packer inside the pipe, centering it in length.
4. Turn the regulator knob all the way counter-clockwise
to lower the pressure to zero. Close the regulator
valve. Attach the pressure regulator at the end of air
push rod. Attach the compressed air supply to the
pressure regulator.
5. Open the regulator valve. Slowly turn the regulator
knob clockwise to inflate the packer to the required
air pressure. Refer to the Specifications table for
pressure values for specific pipe size. Shut the
regulator valve.
