Pressure Balanced Valve
Note:
o During sweating of inlet lines do not overheat casting. Overheating may cause
damage to internal mechanisms and void the manufacturer’s warranty as well
as increase the risk of scalding.
o Do not use plumber’s putty, chemical cleaners or any product with ammonia
on any of the brass components. This will cause the finish to tarnish and void
the warranty. A non-corrosive 100% silicone is recommended.
Features:
• Diaphragm cartridge maintains water temperature within ± 2°F
• Compensates for water pressure fluctuations preventing scalding
Specifications:
Operating pressure is 20 PSI to 145 PSI
Temperature range is 50°F to 180°F
All inlets and outlets are ½” IPS

Note: When fitting handle trim it may be necessary to shorten broach stem and/ or threaded
nipple to eliminate gap between handle and escutcheon.

Pressure Balanced Valve
1. Flush the lines of all dirt and debris. Failure to completely flush the lines will cause valve
failure and will void the manufacturer’s warranty.
2. Position valve in wall with the shower outlet marked “S” up and the tub outlet marked “T”
down. Refer to diagram 2 for proper installation depth.
Note: Protective cover (mud guard) may be removed to ensure proper installation
depth but must be replaced on valve for plastering and/or tiling. Diameter of wall cutout hole around valve is 6 ¼”.
3. Test pipe joints and inspect for any possible leaks, pressuring both the hot and cold inlets,
before attaching the outer trim components.
4. For back to back installations or where the hot and cold water supplies are reversed, turn
off the hot/cold water supplies and then simply take out the cartridge, rotate it 180º and reinsert.
5. Install decorative trim. Fit faceplate onto valve.
Note: for tub/shower valves with diverter, screw diverter knob onto diverter stem.
6. Insert handle trim onto stem broach so that escutcheon rests against faceplate and slight
clearance is left for handle to rotate freely.
Note: When fitting handle it may be necessary to shorten broach stem and/or
threaded nipple to eliminate gap between handle and escutcheon.
Shower head with hand shower installation
1. Choose your primary function device (i.e. where you want the water to first come out
of when turning on the valve).
2. Pipe the bottom outlet marked “T” to this device
3. Pipe the secondary function device to the top outlet marked “S”
Note: The “S” outlet must have a maximum outlet volume of no more than 2.5 GPM.
Adjusting the Temperature Range:
The temperature limit stop is set at the factory in a neutral position. This device can be
adjusted to limit the maximum temperature of water delivered by the valve.
1. Remove all decorative trim.
2. Rotate the cartridge stem fully clockwise to the closed position so that the
mechanical stop rests against right side of the stop post.
3. Remove stem broach by inserting a long narrow Phillips head screw driver
into the center of the broach and unscrewing screw.
4. Lift off temperature limit stop.
5. Rotate cartridge stem counter clockwise to desired maximum temperature.
Place temperature limit stop on cartridge stem against the left side of the stop
post.
6. Rotate the cartridge stem fully clockwise to close valve.
7. Reinstall stem broach with screw onto cartridge stem.
8. Reinstall trim

Troubleshooting
Malfunction
Shower control opening
through hot
Tub filler or shower head
drips after shutting off the
valve
Cause
Hot and cold water supplies
have been connected in
reverse
Water remains in the shower
piping column (this is normal)
Remedy
Rotate cartridge
Incorrect setting of the
mechanical stop against the
stop post causing a partially
opened cartridge
Reset the mechanical stop
as described in “Adjusting
the temperature range”
Cartridge inlet o-rings or the
filter insert o-rings are faulty
Check the o-rings on the
cartridge inlets and the filter
inserts for cuts or damage
and replace if necessary.
Reset the temperature limit
stop as described in
“Adjusting the temperature
range”
Be sure check valves are
both fully open and system is
fully pressurized.
Remove filter inserts and
filters, cartridge, and check
valves, and remove any
Shower insufficiently hot
Incorrect setting of the
temperature limit stop
No flow of hot or cold water
Either the hot or cold side is
not fully pressurized
Debris in the inlet filter and/or
cartridge and/or check valves
Allow approximately 3-5
minutes to drain column.
Do not stop dripping by
applying excessive force
when closing the valve.
