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 suffi cient 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.

seat surfaces.
Pressure balancing piston
housed in spindle assembly is
restricted from free movement
by foreign matter.

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.

Reduce maximum fl ow by using volume control
adjustment on valve or shower head. Th is 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

procedures.
Aft er the
control spindle assembly
(TA-10) is threaded back into the
spindle cap assembly (TA-12A)
ensure control spindle is rotated
