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.

Remove the two Screws with a Philips Head

Screwdriver then slide the Rough-In Template off

the Valve.

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.

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.

Install the Rough-In Template over the Shower Valve being sure the Rough-In Template sits flush against Valve Body. Following

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.

This document describes the installation, operation, and maintenance of the Speakman CPV-PB-PXE and CPV-PB-DV-PXE shower/bath valves.

Function Description:

The Speakman CPV-PB-PXE and CPV-PB-DV-PXE are pressure balance shower/bath valves designed to provide a consistent water temperature and flow. They are suitable for use with showerheads rated at 1.75 gpm (6.6 L/min) or higher. The "DV" in CPV-PB-DV-PXE indicates a diverter function, allowing the user to switch water flow between a showerhead and a tub spout. The "PXE" likely refers to PEX cold expansion connections. The valve includes a Temperature Limiting Stop (TLS) to prevent scalding by setting a maximum hot water temperature.

Important Technical Specifications:

Operating Pressure Range: 20-80 psi.
Maximum Static Water Pressure: 125 psi.
Minimum Flowing Water Pressure: 20 psi.
Minimum Cold Supply Temperature: 40 °F.
Maximum Hot Supply Temperature: 160 °F.
Minimum Hot Supply Temperature: 5 °F above set point.
Showerhead Flow Rate Compatibility: Designed for use with showerheads rated at 1.75 gpm (6.6 L/min) or higher.
Mounting Depth: The distance from the valve mounting surface to the finished wall MUST be between 3-1/8" to 4-1/8".
Tub Spout Distance: A 1'-9" (533mm) minimum distance from the valve body to the tub spout is required for proper operation.
Connections (CPV-PB-PXE):
- Hot/Cold Inlets: 1/2" F1960 Cold Expansion PEX.
- Shower Outlet: 1/2" Female Copper Sweat, 1/2" NPT Male.
- Tub Outlet: 1/2" Female Copper Sweat, 1/2" NPT Male (Cap included for Shower Only Connections).
Connections (CPV-PB-DV-PXE):
- Hot/Cold Inlets: 1/2" F1960 Cold Expansion PEX.
- Shower Outlet: 1/2" Female Copper Sweat, 1/2" NPT Male.
- Tub Outlet: 1/2" Female Copper Sweat, 1/2" NPT Male (Cap included for Shower Only Connections).
Compliance: ASME A112.18.1/CSA B125.1, ASSE1016/ASME A112.1016/CSA B125.16.

Usage Features:

Temperature Limiting Stop (TLS): Factory set at 110 °F, but adjustable to a desired maximum outlet temperature. This feature helps prevent accidental scalding. The adjustment involves removing a collar from the cartridge and rotating it clockwise for hotter or counter-clockwise for colder settings.
Back-to-Back Installation Capability: The valve can be mounted back-to-back with another valve in a shared space, which may involve reversing the HOT and COLD inlets. The cartridge can be rotated 180° to accommodate this configuration.
Diverter Function (CPV-PB-DV-PXE): Allows the user to easily switch water flow between the showerhead and the tub spout.
Rough-In Template: A template is provided to assist with accurate wall cutouts and valve positioning during installation.

Maintenance Features:

Regular Cleaning: The valve should be cleaned periodically with a soft cloth. Harsh chemicals and abrasives should be avoided as they can damage the finish and void the warranty. Only approved cleaners should be used.
Periodic Internal Maintenance: This type of valve requires regular maintenance, at least every 12 months or after any changes to the building's plumbing system. This includes removing and cleaning the spring check stop components and ensuring the stop poppet moves freely.
Winterization: For valves installed outdoors, winterization involves removing all internal parts and draining any standing water from the valve.
TLS Check: Quarterly, the maximum hot temperature setting (TLS) should be checked and adjusted as needed to maintain the recommended 110 °F setting.
Serviceability: The manual provides detailed instructions for removing and replacing key components such as the Pressure Balance Cartridge, Spring Check Stop Parts, and Diverter Cartridge (if present). This facilitates repairs and extends the lifespan of the valve.
Flushing: After installation, the water outlets should be flushed for at least one minute to remove any foreign matter before final use. This helps ensure clean water delivery and proper valve function.
