Before you start:
On multi-story buildings - all pumps, main
and circulator, must be shut down prior to
installation.
On a closed system, you must install TWO Add-
A-Valves® to isolate the problem area.
ATTENTION:
Jomar requires that the Add-A-Valve® installer
view the Jomar installation CD / Video prior to
attempting installation. Failure to do so will
relinquish Jomar from any and all liability for
improperly installing an Add-A-Valve® device.
In this case, Jomar will not be responsible,
nor will it exchange or provide a refund for any
improperly installed Add-A-Valve®.
Copies are available for viewing on the Jomar
website at: www.jomar.com and upon request.
To assist with installation, check off each step as you complete it
Step 1
Before installing the Add-A-Valve®, clean the copper tubing with a fine emery
cloth to a bright shiny finish.
Step 2
Disassemble the Add-A-Valve® body by removing the four (4) 316 stainless
steel bolts.
Step 3
You will be supplied two small tubes of gasket sealant. One tube per body half.
Apply a liberal amount of gasket sealant and brush evenly across the entire body
half surface.
Do this to both body halves and allow 1-2 minutes for dry time.
To ensure proper step order, follow the page numbers > 1

The Jomar Add-A-Valve® is engineered for ONE-TIME
use as an emergency shut-off device! Once the stem
cutter has been raised DO NOT lower it again.
Step 4
Note: Be sure the stem cutter is backed out all the way so that the cutter does
not make contact with the copper tubing.
Assemble the two body halves around the copper tubing and replace the four (4)
316 stainless steel bolts.
Step 5
Using a ratchet and wrench, tighten the four bolts in an ‘X’ pattern to a torque of
95 - 105 in/lb. Be careful not to overtighten, as you may strip the bolts and cause a
leak. If, after proper assembly of the four bolts, you experience a slight gap between
the two halves of the Add-A-Valve®, make sure the gap is evenly distributed on both
sides of the body. A closed gap on one side and an open gap on the other will cause
a leak. Additionally, it will prevent the cutter from making a straight cut and will
damage the pipe, thereby making it susceptible to breakage or a leak.
Step 6
To begin testing your installation, remove the stem and bottom cap and screw on
the test caps that are supplied with your kit.
Step 7
Pump air into both test caps at approximately 15-20 psi. We are testing the
installation sealant and valve bodies for leaks.
Step 8
Now spray the entire body of the valve with a soapy water solution and check for
bubbles that indicate a leak.
If you see any bubbles, reposition or tighten and then retest.
Do NOT proceed with the Add-A-Valve® installation until testing succeeds.
Step 9
When it air tests without leaks, remove both test caps and replace with the stem
cutter and bottom cap.
Note: Be sure the stem cutter is backed out all the way so that the cutter does not
make contact with the copper tubing.
We are now ready to engage the stem cutter.
Use a 3/8” socket
wrench, manual
operation only! Do
NOT use a drill
motor.
Keeping steady
pressure, ratchet
the stem cutter
down until you’ve cut through both walls of the copper
tubing.
CAUTION
Before engaging the cutter, pipe hangar supports should be installed on both sides of the Add-
A-Valve®, 12 inches on center to eliminate stress at the ends of the valve. If hangars cannot be
installed, it is NOT recommended to use the Add-A-Valve®.

recommended to use the Add-A-Valve®.
Step 11
You must now remove both copper slugs and flush the debris. Begin by removing
the bottom cap. There may be some water trapped here. However, if water does
not appear to be completely shut off, remove the bottom cap completely and slowly
ratchet the stem cutter down further until water flow stops.
To remove slugs, take a hammer and a flat head screwdriver and gently tap the high
side of the two copper slugs into a vertical position and remove with needle nose
pliers.
Note: To flush debris, reverse the stem cutter with bottom cap off until you see a
flow of water. Debris should be flushed. Reseat the valve until the flow stops and
replace cap. Congratulations, shut down is now complete! You can now use the
Add-A-Valve® to make a repair or as a live, hot tap. The Jomar Add-A-Valve®
is engineered for ONE-TIME use as an emergency shut-off device!
Once the stem cutter has been raised DO NOT lower it again.

This is a TWO
person operation.
Use a 9/16” socket
wrench on the stem
cutter, and with the
help of a second
person, use an
open end wrench
on the outer stem.
This sets the depth of the cut and prevents the cutter
from binding. Slowly turn both wrenches at the same
time.
SINGLE STEM
For sizes 1/2” to 1”
DOUBLE STEM
For sizes 1-1/4” to 2”
Step 10
When you’ve reached the stop ring, you’ve reached the seating position of the valve. At this
time, ratchet one to one and a half turns to expand the Viton® seal across the two pipe cuts.
Determine what size Add-A-Valve® you have and follow the corresponding directions
