Maintenance Instructions
PROBLEM
Valve will not ow water. Hot and cold water not turned on.
Service Stops not open.
CAUSE
Be sure both supplies are turned on and
service stops are open. Valve will not
operate unless both HOT and COLD
water inlets have pressure.
Replace Hot and Cold washers and in-
spect top surface on hot and cold seats
for damage.
Pressure balancing piston housed in
control spindle assembly is blocked from
free movement by foreign matter.
With valve open half way, remove
temperature handle and tap spindle
with plastic hammer. If problem is
not solved, remove spindle assembly
completely and tap handle end against
a solid object to free piston. Rinse out
control sample assembly. Soaking in
household vinegar will help free foreign
debris matter buildup.
Water volume from valve is inconsistent
during operation.
Reduce maximum ow rate out of valve
or shower head. This will allow longer
period of use before reduction of hot
water supply.
Supply system is running out of hot
water.
Temperatures out of valve reduces
gradually during use.
Hot and cold water washers are worn,
or foreign matter (solder, chips, etc.) are
between washers and seat surfaces.
SOLUTION
Temperatures uctuates without moving
temperatures handle.
Valve delivers an insufcient quantity of
Hot or Cold water.
This is a design function of the valve.
Water is allowed to trickle from the tub
spout when diverter is set in shower
position; in accordance to national
standards.
While using a tub & shower valve with
integral diverter set for shower, a trickle
of water runs from tub spout.
Back to Back Installation Drawings
Valve makes loud noise. Piston in stem is moving back and forth
because of a large pressure differential
between the HOT and COLD water
lines.
Alter the water system such that the
pressure differential at all shower valves
is no more then 5 psi.
NOTE: It is recommended that when any TG1 shower valve is rst installed on a new large system or in an excessively dirty system, that the hose bibb
ushing out kit (RK7000-20HB) be used to clean the valve of debris from the installation of the water system. To do this, remove the spindle assembly
per the service instructions and replace with the hose bibb bonnet nut. Attach a garden hose to the bibb to direct the water to a drain. Open both service
stops and allow the water to run for several minutes. Once the system is completely ushed out, replace the hose bibb with the spindle assembly. Open
valve to ush out any debris that may be in the spindle.
NOTE: If the shower valves are going to remain unused for an extended period of time (over 3 months) then the water should be shutoff to the valves (via
service stops or system control valve) and each valve should be opened to allow the water in the valve to evaporate. This is to keep the piston from sticking,
due to stagnant or hard water, once the valve is in use again. If piston does stick, soak the valve assembly in vinegar per the maintenance instructions.
Valve leaks when shut-off.
The ZURN TEMP-GARD Pressure Bal-
ancing Shower Valve is equipped with an
adjustable limit stop screw. The limit stop
device is to be used to limit the valve handle
from being turned to undesired hot water
discharge temperatures. To adjust the limit
stop screw, remove handle and escutcheon,
turn valve to maximum desired temperature
and turn the limit stop screw until it seats.
IMPORTANT: Failure to adjust the limit
stop screw properly increases the chanc-
es for serious injury.
