WARRANTY
Your new Shower/Bath Valve is designed for years of
trouble-free performance. Keep it looking new by
cleaning it periodically with a soft cloth. The use of
harsh chemicals and abrasives on any of the Speakman
custom finish products may damage the finish and void
the product warranty. Please be sure to only use
approved cleaners. Please contact Speakman for any
clarification of acceptable cleaners.
MAINTENANCE
Cover your drain to prevent loss of parts. Be sure to
wear eye protection while cutting pipe.
SAFETY TIPS
IMPORTANT
• Be sure to read instructions thoroughly before
beginning installation.
• Be sure to have properly adjusted the Temperature
Limiting Stop (TLS) as outlined in this Installation
Manual.
• Inspect all connections after installation of valve.
• This valve has an operating range of 20-80 psi.
• This valve is designed to be used in conjunction
with a shower-head rated at 1.75 gpm (6.6 L/min)
or higher flow rate.
• NOTE: This installation manual covers several
models of valves. While the appearance of your
valve may differ from those shown, the installation
method is the same.
• Maximum water pressure: 125 psi static; minimum
water pressure: 20 psi flowing; minimum cold
supply temperature: 40 °F; maximum hot supply
temperature: 160 °F; minimum hot supply
temperature: 5 °F above set point.
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 and
adjusted accordingly.
1
Remove the two Screws with a Philips Head
Screwdriver then slide the Rough-In Template off
the Valve.
2
Referencing the supplied rough-in dimensions
(located at the end of this manual), determine the
preferred location of Valve. Align the supplied
Rough-In Template with this location and trace
outline of Template onto wall. Using a Keyhole
Saw or similar tool, cut along traced line and
remove this section of wall.
3
Shut off the water supply to the Tub and Shower. Verify that the hole sizes and
positions in the wall are correct:
A. The shower and tub spout outlet holes should be 1” diameter.
B. To determine the Valve mounting depth, see STEP 4.
C. The distance from the Valve mounting surface to the finished wall MUST be
between 3-1/8" to 4-1/8". Position the Valve Body ❶ correctly in the wall with
the “UP” pointing up. The 1’-9” minimum from the Valve Body to the Tub Spout is
required for proper operation.

the rough-in dimensions for your model of valve (located ot the end of this manual) as well as the markings on the supplied
Rough-In Template, install valve at proper depth. The distance from the Valve mounting surface to the finished wall MUST be
between 3-1/8" - 4-1/8". See images below for reference.
