Trouble Shooting Guide
Problem
Water drips from spout or valve stem assembly.
Possible Cause
Flat washer on the stem/plunger is worn.
Water leaks from the front of the valve.
O-Rings on the plunger are worn out.
To Diagnose
To determine if the leak source is from the hot or cold side shut cold water source off. See if water still leaks from the spout. If leak continues then repair hot side if not repair cold side.
Visually determine whether the cold or hot side is leaking.
Remedy
We recommend installing valve repair kit.
We recommend replacing threaded insert, plunger assembly & spring.
See illustrations below.
