Problem
Valve will not pass water.
Valve leaks when shut off.
Temperature control handle is
turned from cold to hot (or hot
back to cold) and volume from
spout or head is not constant.
Valve delivers sufficient quantity of
cold, but little hot, or the reverse.
Temperature varies without
moving handle.
Valve delivery temperature reduces
gradually during use; handle must
be turned to hotter positions to
maintain constant temperature.
Valve delivers hot water when
initially opened. Water turns
colder as handle is rotated in
a counter-clockwise direction
toward the hot position.
Service Instructions
Removing control spindle assembly
(Ref. Parts Assembly figure)
■ Shut off water supply to valve
and remove control valve handle

Important:
do this can damage

Cause
Both hot and cold water supplies are
not turned on.
Hot and cold washers are worn or
foreign matter (dirt, chips) is lodged
between washers and seat surfaces.
Pressure-balancing piston housed in
spindle assembly is restricted from free
movement by foreign matter.
Same as above
Same as above
Overdraw on hot water supply
(i.e. running out of hot water).
Valve is piped incorrectly (i.e. the hot
supply is piped to the valve's cold inlet
and the cold supply is piped to the hot
inlet.)
.
■ Replace both seats even if only
one appears worn.
■ Install and tighten both seats to
15 foot pounds of torque.
Control Spindle Washer Repair Kit
Order p/n TA-9.
■ Remove control spindle assembly
■ Remove cold washer by holding
spindle using valve handle and
unscrew cold washer retainer
using channel lock pliers.
Failure to
■ Remove hot washer by removing
hot washer screw.
Checking Water Pressure
and
Balancing Piston
The perforated end of the control
spindle assembly houses the water
pressure balancing piston which is
the heart of the valve.
■ Remove control spindle assembly.
.
■ Shake spindle assembly and listen
for clicking noise. Piston should
be free to slide back and forth the
full length of its travel.

Solution
Turn on both supplies. Valve will not operate
unless both hot and cold water pressure is on.
1) Replace washers using control spindle
washer repair kit, p/n TA-9.
2) Replace hot & cold seats using hot/cold
seat repair kit, p/n TA-4.
1) Open valve halfway, remove handle and
tap spindle with plastic hammer.
2) Check water pressure balancing piston in
control spindle. See service instructions.
3) Replace control spindle, p/n TA-10.
Same as above
Same as above
Reduce maximum flow by using volume
control adjustment on valve or showerhead.
This will allow longer period of use before
overdrawing hot water supply.
If piping is accessible, correct connections to
the valve. If piping is not accessible, order
a reverse seat and tool kit, p/n T-108. Older
installations may also require replacing the
hot seat, hot/cold seat repair kit, p/n TA-4.
■ If piston appears restricted then
do the following:
(1) Tap the handle or stem end of
the spindle against a solid object
to free the piston.
(2) Try soaking in household
vinegar and repeat step (1).
.
■ If unable to free piston, replace
control spindle
Important:
attempt removal of
the piston.
Valve re-assembly
Reassemble by reversing above
procedures.
After the
control spindle assembly
(TA-10) is threaded back into the
spindle cap assembly (TA-12A)
ensure control spindle is rotated 1/2
turn clockwise from its maximum
counter clockwise rotational
position. Failure to do this will
damage assembly.
