MAINTENANCE (CARE and CLEANING)
The Speakman Sentinel Pro thermostatic/pressure balancing shower /bath valve should provide years of reliable
service. This type of valve must be cleaned and maintained on a regular basis. Periodic maintenance should be
performed at least every 12 months or after any changes have been made to the building’s plumbing system. This
maintenance should include removing and cleaning the spring check stop components. Make sure the stop poppet in
each stop moves freely. Valves that are installed outdoors should be winterized by removing all of the internal parts
and removing any standing water from the valve. Quarterly the maximum hot temperature setting (TLS) should be
checked (See Step #5 of the installation instructions). For servicing the valve, see the instructions below. The gleaming
finish of your SPEAKMAN Sentinel Pro valve can be cleaned by using mild soap and warm water. Dry immediately
with a soft, clean cloth for best results.
SERVICE INSTRUCTIONS
Caution- Any repair or servicing of the valve may affect the maximum hot temperature setting of the valve.
After working on the valve, make sure the maximum hot water temperature is set to the recommended setting
of 110° F maximum.
1) T/P Cartridge Removal
- Shut off the hot & cold water supply integral stops at the valve. Remove handle index
button & handle. Remove index retaining ring & index. Remove wall plate screws (2) & wall plate. Remove the
trim sleeve.
2) With the valve in the OFF position, remove the retaining o-ring and TLS plate from the valve spindle. Remove the
TLS ring from the valve cartridge. Remove the (4) valve bonnet screws and carefully remove the bonnet. The
cartridge may come out with the bonnet.
3) If necessary remove the cartridge from the valve body by pulling on the valve spindle of the cartridge. Make sure
the lower rubber quad rings (2) are installed in the bottom of the cartridge and not in the valve body.
4) Replace the necessary parts with new parts. When replacing the T/P cartridge, make sure that the rubber quad-rings
(2) are properly installed in the recesses on the bottom of the cartridge. These quad-rings seal over the hot & cold
inlet holes inside the body. When replacing the cartridge, refer to Figure #4 for proper positioning of cartridge in the
valve body.
5) Make sure the large bonnet o-ring seal is installed and seated properly in the valve body. Reassemble the valve
bonnet, making sure the “UP” on the bonnet is in the up position. Tighten the (4) bonnet screws. Reassemble the
TLS ring onto the cartridge, so that the ring’s lower lug (with hole) is positioned between the bonnet lugs (2).
Important- Adjust the valve’s maximum hot water temperature to the recommended setting of 110° F.
See
Step #5 of the installation instructions for the TLS adjustment instructions.
6) Turn ON the hot & cold water supply integral stops. Check valve for leaks.
7) Reassemble the trim parts, reversing the above procedure (Also see Step #6 of the installation instructions).
1) Spring Check Stop Parts Removal
- Shut off hot and cold water supply valves to the integral stops of the valve.
Remove handle index button & handle. Remove index retaining ring & index. Remove wall plate screws (2) & wall
plate.
2) CLOSE integral stops by turning the stop spindles clockwise. Unscrew the stop’s retaining nut with wrench.
Carefully remove the retaining nut w/spindle, spring, and poppet assembly. Clean and/or replace the necessary
parts. Reassemble the parts, reversing the above procedure. Repeat procedure on the other stop.
3) OPEN the integral stops by turning the stop spindles counter clockwise. Turn on the hot and cold water supply
valves. Check for leaks.
4) Reassemble the trim parts, reversing the above procedure (Also see Step #6 of the installation instructions).
