Step 4
Assemble the two body halves
around the copper tubing.
NOTE:
Be sure the stem cutter is
backed out all the way so that the
cutter does not make contact with
the copper tubing.
Step 6
To test the installation, perform an air test. To perform an air test,
remove the stem and bottom cap and screw on the test caps that are
supplied in the kit.
Step 7
Pump air into both test caps at approximately 15-20 PSI. This tests the
installation sealant and valve bodies for leaks.
Step 8
Spray the entire body of the valve with a soapy water solution and
inspect the valve for bubbles.
If bubbles are visible, reposition or tighten to ensure a tight fit and no
leaks, then retest the Add-A-Valve.
DO NOT proceed with the Add-A-Valve® installation until testing
succeeds.
Step 5
Using a ratchet and wrench,
tighten the four (4) 316 stainless steel bolts in an ‘X’
pattern to a torque of 95 - 105 in/lb.
Do not overtighten, as you may strip the bolts
and cause a leak. If a slight gap between the two halves of the Add-A-Valve® is
detected, make sure the gap is evenly distributed on both sides of the body.
NOTE: 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.
Ensure even gap
distribution on all axes/
directions.
CORRECT
INCORRECT
Uneven gap distribution
can lead to install failure.

CAUTION
Pipe hanger supports should be installed on
both
sides of the Add-A-Valve®
to eliminate stress at the ends of the valve. If hangers cannot be installed, it is
NOT recommended to use the Add-A-Valve®.
