Cannot receive more than a trickle of water:
Both hot and cold supply lines must be
pressurized. If only one side is pressurized, the
system will not allow adequate flow of water.
Faucet leaks from showerhead:
Remove
the showerhead then turn the water on and
off to verify if the cartridge is leaking or the
showerhead is draining slowly (the showerhead
may need to be cleaned if water drains slowly).
If leak persists -
SHUT OFF WATER SUPPLIES
Replace cartridge assembly - RP47201.
Unable to set or maintain mixed water
temperature:
SHUT OFF WATER SUPPLIES. Remove handle
assembly, trim sleeve, and bonnet nut. Check
to make sure the “H” marking on the cartridge
aligns with the hot inlet and the “C” marking on the
cartridge aligns with the cold inlet to the valve body
The thermostatic cartridge cannot function if hot
and cold inlets are reversed.
Low flow:
Low flow may be caused by clogged screens within
the thermostatic cartridge. To clean the hot and cold
screens in the cartridge, follow the steps below:
1. SHUT OFF WATER SUPPLIES.
2. Remove the handle assembly.
3. Unscrew the hex shaped portion of the cartridge
from the brass section of the cartridge. the brass
section must be held securely by the flats while
the hex is rotated counter-clockwise. Failure to
secure the brass section while rotating the
hex can result in damage to the cartridge.
4. Carefully clean any debris from the screens
under running water. If the debris is difficult to
remove then soak the screens overnight in a
50% water and 50% vinegar solution.
5. Reassemble the cartridge.
6. Replace the handle.
7 Turn the water back on.
8. Reset the limit stop before using the valve.
