PROBLEM
Valve will not flow water.
Valve leaks when shut off.
Temperature control handle is turned from
cold to hot (or hot to cold), and volume from
spout/head is not constant.
Valve delivers sufficient quantity of cold, but
little hot (or the reverse of this).
Temperature varies without moving the handle.
Valve delivery temperatures reduces gradually
during use; handle must be turned to a hotter
position to maintain constant temperature.
CAUSE
Hot and cold water not turned on.
Hot and cold washers are worn, or
there is foreign matter between
washers and seat surfaces.
Pressure balancing piston housed in
spindle assembly is blocked from free
movement by foreign matter.
Same as above.
Same as above.
Overdraw on hot water supply; i.e.
running out of hot water.
SOLUTION
Turn on both supplies.Valve will not operate unless
both hot and cold water pressure is turned on.
Replace hot and cold washers; inspect top surface
on hot and cold seals; replace if necessary.
With valve open halfway, remove handle and tap
spindle with plastic hammer. If problem is not solved,
remove spindle assembly completely and tap handle
end against solid object to free piston. Soaking in
household vinegar will also help free foreign matter.
Same as above.
Same as above.
Check hot water source.
