Description
The RIDGID® Pipe Patching System is a trenchless pipe
repair and relining system. The system repairs cracks,
holes, joint separation and other damage in a variety of
pipe types, such as clay, concrete, cast iron or PVC.
The system uses a cylinderical fiberglass patch wet out
with silicate resin. The patch is mounted on the inflatable
installation tool (the “packer”) and placed at the point of
repair by pushrod or ropes. The packer is inflated to press
the patch inside the repair point. When the resin is hardened, it creates a seal in the damaged area.

Glossary of Common Pipe
Patching Terms
Containment
Liner ...................The restrictive liner used to prevent the
packer from over inflating in sections of
pipe with bends.
Containment
Tube ...................The restrictive tube used to prevent the
packer from over inflating in straight sections of pipe.
Encroachment
Zone ...................The area at each end of the packer that
will not expand to the full to the pipe diameter when inflated. The patch CANNOT be in this zone. If the patch is in this
zone, the patch will not be proper and
may block the pipe. The encroachment
zone is measured from the point where
the black rubber meets the metal end of
the packer. This zone is 3" long for the 2"
& 3" packers and 5” long for the 3"-4" &
4"-6" packers.
Final Hardness Time (Also Known As
“Cure Time”) .......The time at which the patch has reached
its full hardness and is as strong as it will
get.
Flexible
Adapter ...............The short flexible air fitting assembly
located at the back end of the packer
which the Air Push Rod or the Patching
Air Hose connect to.
Internal Pipe
Temperature .......The temperature inside the pipe to be
patched, at the area to be patched. Higher temperatures decrease resin set time,
lower temperatures increase set time.
Packer ................The inflatable bladder used to inflate and
hold the patch in place against the inside
of the pipe while the patch hardens and
cures.
Packer Sleeve ....The clear protective sleeve used to cover
the packer and prevent contact with the
resin.
Packer Test Insertion (Also Known As A
“Dry Run”) ..........The process of ensuring that the packer
is able to navigate the pipe to the point
of repair. During the test insertion, the
packer should have a packer sleeve installed on it to protect the packer and
packer sleeve is lubricated with oil soap
to simulate the resin.
Patching Air
Hose ...................Used in place of the push rods and at-
tached to the air fitting on the packer
when pulling the packer into place.
Resin Set
Time ...................The time required for the resin to suffi-
ciently harden to allow the packer to be
deflated and removed. Resin set time is
temperature dependent. At this time, the
pipe can be put back into service.
Pre-Operation Inspection
WARNING
Before each use, inspect your pipe patching system and correct any problems to reduce the risk of
serious injury from chemical burns, infections and
other causes and prevent system damage.

properly.
Set-up And Operation
WARNING
Follow all instructions and warnings for resins.
Refer to the resin labeling and SDS for more information. This will help reduce the risk of health
hazards due to exposure to resin material.
Do not leave mixed resin in container. Chemical reactions during curing generate heat. If kept in the
container, that heat could damage the container
and cause burns. Empty all mixed resin onto patch
and spread out. Excess resin can be left to dry on
the protective table covering.
Do not inate the packer outside of an appropriately sized pipe. Do not inate the packer without
packer sleeve/patch/appropriate containment on
the packer per these instructions. This will reduce
the risk of the equipment bursting and causing
serious damage or injury.
Do not over-pressurize the equipment. This will
reduce the risk of the equipment bursting and
causing serious damage or injury.
Follow setup and operating instructions to reduce
the risk of injury from chemical burns, infections
and other causes, and prevent system damage.
1. Check work area for:
• Adequate lighting.
• Place out of direct sunlight for mixing resin, near
the point of insertion in the pipe.
• Clear, level, stable, dry location for all equipment
and operator.
• Confirm that there is sufficient ventilation. When
working indoors, windows may need to be opened
and/or powered ventilation may be needed to
remove resin fumes.
• Clear path between patch wet out area and point
of insertion in pipe.
2. Make sure all equipment has been properly inspected.
Proper pipe patch installation is dependent on preparation and timing. Figure 7 shows the general pipe patching
steps. Every Pipe Patching job is different and requires
Always wear appropriate personal protective equipment. Appropriate personal protective equipment
always includes safety glasses and chemical resistant gloves and may include equipment such as
face shields, long sleeves, safety shoes, hard hat,
and respirator as appropriate. This will reduce the
risk of injury.
Pipe patching resin fumes may irritate the skin
and lungs or damage the eyes. Refer to the resin
labeling and SDS for more information.
Drains may contain chemicals, bacteria and other
substances that may be toxic, infectious, cause
burns or other issues.

Pipe Patch
If the packer is not properly supported, the patch
can bulge into the unsupported area and/or the
packer can be damaged or burst. In these cases,
the proper containment material must be used
(see “Containment” section).
• Pipe size(s), type(s), transitions, traps, shifted pipe
and other obstacles present that could prevent
packer insertion or cause damage. The transitions
in pipe system may require a smaller size packer.
• Best access to area to be patched. In some cases,
it may be necessary to have access on both ends
of the pipe to be patched to allow the packer to be
pulled into position. Determine how the packer will
be moved into position. A test insertion is required
to confirm that the packer can be placed properly.
• Visual inspection of the pipe is required. Multiple
visual inspections will be required throughout the
patching process. While inspecting, determine
the temperature of the pipe to be patched. If the
pipe is hotter or cooler than the resin application
temperature (41°F to 68°F (5°C to 20°C)), the resin
set time will be affected. Lower temperatures will
increase set time and higher temperatures may
decrease set time.
2
CLEAR ALL BLOCKAGES AND CLEAN THE LINE WALL-TO-WALL
2. Thoroughly clean the pipe system. Remove all debris,
roots and other materials that can block the movement of packer into place or damage the pipe patch
and equipment inside pipe. (Figure 7-2). Pipe should
be cleaned to the pipe base material. When working
in PVC or other plastic pipe, in addition to cleaning
to the base material, the cleaning method needs to
“roughen up” the base material. This “roughening up”
helps to provide mechanical bonding of the patch to
the pipe.
Clean past the damage to allow water and debris
to drain from the area. Area should be flushed and
fluid flow shut off. Pipe can be patched with small
amounts of water in the drain, but less water in the
area is better. While the drain does not need to be
perfectly clean, any material left in the drain may
make the patching process more difficult and prevent
proper sealing.
3
RE-INSPECT THE LINE TO ENSURE IT IS FREE OF DEBRIS AND
CONFIRM LOCATION AND SIZE OF REPAIR
3. Reinspect the drain with the camera. Confirm that the
drain is properly cleaned and meets the requirements
for patching. Ensure that the pipe is free of sharp
features that could damage the packer, such as
broken sections of pipe. Position the camera head
at the center of the damaged area to be patched
and mark the camera push cable (for example with
tape around the push cable, See Figure 8) near the
pipe entrance. This will be used to determine the
measurement to the damaged area for patching. See
Figure 7-3.
4. In an open area, layout the camera push cable so that
the mark on the push cable is visible. Measure the
distance from the camera head (patch location) to the
mark on the camera push cable to confirm how far into
the drain the patch will be placed. See Figure 8.
5. Determine if the packer will be put in place using the
air push rod, a pull rope, or a combination of both. A
pull rope is always used at the same end as the air
push rod. If using a second pull rope from other side
of the packer, route the rope through the pipe. NOTE:
The push rods cannot be used to push through P
traps or bends in pipe size 3" or under. In this case,
the lockable air hose will be attached to the back of
the packer with a pull rope on each end of the packer.
Air Push Rods
Assemble enough air push rods to reach the patch
point. Lay the assembled packer and attached air
push rods next to the camera push cable. Mark the
air push rod at the same distance as the mark on
the camera push cable, see Figure 8. This will help
properly locate the patch in the pipe. Remove one
air push rod that will later be attached to the packer
when installing the packer sleeve.

If using a pull rope on the front of the packer, the
packer ball will need to be unscrewed and the rope
attachment eye bolt screwed in place (See Figure
10). Rope can be attached directly to the eye bolt, or
the supplied D-ring or quick link. Securely attach the
pull ropes.
When using only pull ropes, attach the air hose to
the packer and lay the assembled packer and hose
next to the camera push cable. Mark the air hose at
the same distance as the mark on the camera push
cable (Similar to Figure 8). This will help properly
locate the patch in the pipe.

7. Prepare the packer for the test insertion. Install packer
sleeve.
Installing Packer Sleeve
The packer sleeve protects the packer from the resin and
simplifies clean up.
1 Confirm that you have the correct packer, equipment
and materials for the patching work.
2. If needed, install containment on the packer (see
Containment section – Containment not used for test
insertion) .
3. Lay out the plastic table covering to protect your
selected work area from the resin and keep material
and equipment clean.
4. Make sure that the packer is clean. If needed, apply
baby powder to the rubber portion of the packer and
clean up any excess baby powder in the work area.
5. Insert the packer inside the provided clear packer
sleeve. See Figure 12.
Figure 10 – Removing Packer Ball/Installing Eye Bolt
6. Set up air supply and run an air hose to the point
of use. Attach the regulator to the air hose. Pull the
regulator adjustment knob out and turn clockwise to
confirm that there is adequate pressure (at least 100
psi) available to the regulator. Air pressure must be
available throughout the patching process to ensure
a complete patch. Pull the regulator adjustment
knob out and turn counterclockwise to reduce the air
pressure to zero. See Figure 11. Place regulator out
of way until ready to inflate the packer.

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.
Pipe Patch
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 containment/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 jobsite 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.

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.
ENSURE PACKER CAN BE NAVIGATED TO THE PATCH LOCATION BY
PERFORMING A TEST INSERTION
1. Make sure that the correct packer is properly prepared, 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.

Pipe Patch
Containment
If the packer will be placed such that portions of the
packer will be unsupported (such as T’s or pipe damage
over 1" in diameter, connections, breaks, or the packer
extends into a larger size pipe or out of the drain) then
containment must be used. Additionally, if the pipe is
believed to be brittle (based on material, age, inspection
results, etc.), containment should always be used.
Containment can be done with a:
Containment Tube
• containment tube (for straight pipes)
Containment Liner
(Loop Stitch Material)
Figure 20 – Minimum Containment Tube Length
1. Using sharp scissors, cleanly and squarely cut the
containment tube to length. A clean, square cut will
minimize tearing when inflating.
2. Place the containment tube over the packer, lining it
up with the end of the packer.
• containment liner (loop stitch material) (for use in
bends).
Figure 19 – Containment Examples
Containment reduces the risk of the patch bulging into
the unsupported area and/or the packer being damaged
or bursting. Containment is always done under the packer
sleeve and will be removed with the packer after the
patch is complete. Because the packer diameter is larger
than it normally would be, a pull rope may be needed to
pull the packer into place. Containment tube and liner
can be reused, but if it is, it should be inspected to make
sure that it is in good shape and not damaged.
Containment Tube
The containment tube is used for straight pipes when
containment is needed. Containment tubes can be used
at one end, both ends or over the full packer.
For Ends Only
Determine the containment tube length. At a minimum,
the containment tube should be at least 12" (305 mm)
long and must extend at least 4" (100 mm) under the
patch. If applying a patch less than full length, the tube
can extend more than 4" under the end of the patch, but
no less. See Figure 20.
3. Place the packer in the middle of the width of the
tube. Fold the edges of the tube up and tight to the
packer. See Figure 21.

5. Use provided elastic bands doubled over individually
every 9"-12" to keep the containment tube neatly
folded and secured to the packer body.
6. Continue building out your packer as normal by
installing the packer sleeve.
For Full Packer
1. Measure the Containment tube to cover the entire
packer, including the hose and locking connector,
See Figure 23.
For the 2" Packer the locking connector does not
need to be covered. The length of the containment
tube should be the length of the 2" packer plus 4".
6. Use provided elastic bands doubled over individually
every 9"-12" to keep the containment tube neatly
folded and secured to the packer body.
7. Continue building out your packer as normal by installing the packer sleeve.
Containment Liner
Containment liner is required when patching through
bends to prevent wrinkles. Examples can be large holes
or corrosion in a bend. Using containment liner will increase the overall diameter of the packer making it tighter
in pipe but will not restrict the packer from navigating the
bends. Containment liner has loop stitch on the inside.
Containment liner cannot be used as a patch and patch
cannot be used as containment liner.
1. Measure the containment liner to cover the entire
packer end to end, including the metal ends of the
packer. See Figure 25.

2. Using sharp scissors, cleanly and squarely cut the
containment liner to length.
3. Slide the containment liner onto the packer. Baby
powder can be used on the packer to more easily
slide the liner over packer.
4. Tightly apply tape to the containment liner over the
metal ends of the packer as shown in Figure 26.
Tape should start where the black rubber of the
packer meets the metal head and continue over the
rounded end (but not cover the threaded connector).
The tightness of the tape over the rounded end holds
the containment liner in place. See Figure 26. Apply
doubled over elastic bands every 12". If needed, the
liner can be folded over.
1. Confirm that the packer is correctly prepared. Any
needed containment should be in place and the
packer sleeve installed.
2. Lay the patch next to the packer, centered along the
length. Confirm that there are equal lengths of black
rubber packer at either end of the patch – these are
the encroachment zones. Encroachment zones are
important to the proper installation of the patch. If the
patch is too close to the ends of the packer (in the
encroachment zone), the end of the patch will not be
held tightly to the pipe inside diameter and the patch
may not work. See the Specifications Table for the
minimum encroachment zone for each packer.
Encroachment Zone - The area at each end of the
packer that will not expand to the full to the pipe diameter when inflated. The patch CANNOT be in this
zone. If the patch is in this zone, the patch will not be
proper and may block the pipe. The encroachment
zone is measured from the point where the black
rubber meets the metal end of the packer. This zone
is 3" long for the 2" & 3" packers and 5" long for the
3"-4" & 4"-6" packers.
If containment is being used on the packer, the end
of the encroachment zone can be found by feeling for
the transition from the hard metal end of the packer
to rubber section.
Figure 26 – Packer With Liner, Ends Taped, Doubled Over
Elastic Bands Applied Every 12"
5. Continue building out your packer as normal by installing the packer sleeve. Pulling the patch onto the
packer with containment liner will be difficult.
Preparing The Patch
Always wear safety glasses and the provided protective
gloves when handling the resin. Prepare the patch and
resin only on the supplied table covering.
See resin containers and SDS for further information on
proper handling and use.
Once the resins are combined, the patching process
is time limited and must be completed within the
resin working time. If time runs out before the packer
is inflated in place, the patch must be disposed of
and the process restarted. Be sure all materials, equip-
ment and personnel are available and properly staged to
minimize the time it takes to get the patch prepared and
in place.
If the encroachment zones are less than specification,
then the patch should be carefully trimmed with sharp
scissors to allow at least the minimum encroachment
zone at either end of the packer.
Once patch length, position and encroachment zones
are confirmed, using a permanent marker, mark the
end locations of the patch on the packer sleeve. See
Figure 27.

Wet Out Patch With Resin
Mixing Resin
3. Confirm that you have the correct patch resins – you
will always be mixing a set of two containers, one
marked “Part A” and one marked “Part B”. Both
containers should be marked for the same length
of the patch (32" or 3'). If making a 6' patch you will
need two sets of 3' containers. Confirm the use by
date is still good. Do not use out of date resin – this
can cause an improper patch.
4. Confirm that the patch resins are within the resin
application temperature. If they are outside of the
application temperature take appropriate steps to
bring them within temperature, such as placing the
unopened resin containers in cool or warm water
bath. If they are too warm, the resin will harden more
quickly, and if too cool, the resin will harden more
slowly.
5. Carefully open both resin containers. Pour all of Part
A into Part B. Securely replace the cap on resin and
vigorously shake the container for at least a minute to
thoroughly mix. Record the time that the resins were
poured together.
Figure 28 – Wetting Out The Patch Off The Packer
2. Carefully insert the packer into the patch (Figure 29).
Do not stretch or deform the patch. Position the patch
at the center of the packer assembly. Confirm that
the patch is centered and encroachment zones (as
marked earlier) are visible at each end. It is important
to have the patch centered on the packer to reduce
the risk of an improper patch. Confirm that the patch
is properly placed relative to any containment tube.
Wet Out Patch Off Packer
This is the generally recommended wet out method.
Wetting out the patch off the packer typically makes it easier to fully saturate the patch with the resin. This method
Figure 29 – Inserting The Packer In Patch
cannot be used for the 3"-4" packer.
1. With the patch in the middle of the table covering,
mix the resin and carefully open. Pour all the resin
mixture on the patch. Do not keep the mixed resin in
the container, it will start to heat up and may rupture
or melt the container.
3. Gather the excess patch together and fold over neatly
(see Figure 30). At the front end of the patch apply
a doubled over elastic band at the front edge of the
patch and every 1/2" past that until there are 4 elastic
bands in place. Continue to place doubled over

This method is always used on the 3"-4" packers and
when using containment on the 3" packer. Prior to mixing
the resin, carefully insert the packer into the patch. Do
not stretch or deform the patch. Position the patch at the
center of the packer assembly. Confirm that the patch is
centered and encroachment zones (as marked earlier)
are visible at each end. It is important to have the patch

1. Change gloves.
2. If needed, attach the ball & spring leader guide to
the front of the packer. The leader guide will help the
packer negotiate bends and p-traps. Otherwise, if not
using a pull rope at the front of the packer, securely
install the packer ball.
3. Securely attach the remaining air push rods, pull
ropes and air hose assembly to the packer. Tape the
connections to reduce the risk of resin getting in the
fittings or the connection from coming loose.

4. If needed, a small amount (up to 8 oz.) of an oil
type soap can be placed in the pipe to lubricate the
equipment as it is inserted.
5. Insert the packer assembly inside the pipe system.
Using the information learned from the test insertion,
work the patch into the place (see Figure 7-5). When
the insertion mark on the air push rod or air hose
aligns with the pipe entrance, inspect the patch position with the camera and confirm correct positioning.
Patch must be properly positioned prior to inflating
the packer. Confirm time since the resin was mixed.
Do not exceed the allowable working time. Wrapping
the camera inspection head spring with tape can help
to prevent resin from accumulating and drying in the
spring.

PREPARE THE PATCH AND POSITION THE PACKER IN
THE PROPER LOCATION
6. Attach the pressure regulator to the air push rod or air
hose.
7. Open the regulator valve. Pull the regulator knob and
slowly turn the regulator knob clockwise to inflate the
packer to the required air pressure (Figure 7-6). Refer
to the Specifications table for pressure values for
specific packer size. Note the time that the packer
was inflated. If you have exceeded the allowable
working time since the resin was mixed, the
packer/patch will need to be removed and you will
need to start with a new patch. See Figure 34.
Always use the pressure regulator on packer. Ex-
ceeding the maximum pressure, may result in the
packer rupturing. Incorrect inflation of packer could
result in the patch collapsing, or not opening up to the
full pipe diameter. This could also lead to the packer
becoming stuck in the pipe.
Once the packer is properly inflated, inspect the patch
position with the camera again to confirm correct.
Continue to monitor the air pressure to confirm that
it does not unexpectedly decrease. Do not shut the
regulator valve or change the air pressure.
6
INFLATE THE PACKER TO THE REQUIRED PRESSURE.
ALLOW THE RESIN TO CURE FOR THE RESIN SET TIME
Wipe up any spilled resin, allow to harden and dispose.
8. Allow the resin to cure for the appropriate amount
of time (“Set time”). Generally, the resin set time is
90 minutes. If the internal pipe temperature is below
50°F (10°C), set time is 180 minutes. If the pipe being
patched is outside of the resin application temperature
range, resin set time will be affected and further adjustments may need to be made. Lower temperatures
will increase set time and higher temperatures may
decrease set time. FULL CURE TAKES PLACE AT 4
HOURS under normal conditions.
Do not depressurize the packer before the set time is
complete. This could cause improper sealing, failure of
the patch, and blockage of the pipe.
9. Depressurize the system to loosen the packer assembly from the patch. See Figure 7-7.

10. Remove the air hose connection and pressure regulator 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 multiple 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
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 maintenance.
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.

6. Wait for 5 minutes and check the air pressure. If the
pressure has dropped, there is a leak, do not use the
packer until the leak is fixed. Leaks in the connections
may be able to be fixed by tightening connections or
lubricating seals. If the packer itself is leaking, it can
be sent for service.
7. After the test is complete, depressurize the system
and disassemble.
