TENZO PRO R-PB23-N Rough-In for 2 & 3 functions pressure balanced valve

A shower valve determines the entire shower experience. The wrong valve means inconsistent temperatures, weak water pressure, or limited functionality. The TENZO PRO R-PB23-N rough-in valve solves these problems.

This pressure balanced rough-in valve is designed for 2 or 3 function shower systems. The pressure balance mechanism monitors hot and cold water pressure. When pressure fluctuates, such as when a toilet is flushed, the valve adjusts the water mix to maintain consistent temperature. No sudden hot or cold surprises.

Pressure Balanced Technology

The pressure balanced valve uses a piston or spool mechanism inside the cartridge. This mechanism responds to pressure changes in the water supply lines. When cold water pressure drops, the valve instantly reduces the hot water flow to maintain the temperature balance. The response happens in milliseconds, protecting against scalding or freezing.

The valve delivers 25.5L/min (6.7 GPM) at 60psi. This high flow rate supports multiple outlets simultaneously. The adjustable temperature limiting device prevents water from exceeding a safe maximum temperature. The adjustable flow limiting device helps control overall water consumption.

2 or 3 Function Capability

The R-PB23-N supports both 2 and 3 function configurations. Two function systems typically operate a rain shower head and a handheld shower. Three function systems add a third outlet, such as body jets or a tub spout. The valve’s diverter cartridge determines the specific configuration.

Two diverter cartridge options are available. The non-shared diverter cartridge (CAR-HA-DV3-NS-33097-01) allows independent outlet operation. The shared diverter cartridge (CAR-HA-DV3D-33097-01) enables simultaneous water flow from multiple outlets.

Installation Features

The rough-in valve includes several features that simplify installation. Integrated check-stop valves allow service without shutting off the main water supply. A test cap enables pressure testing before the cartridge is installed. The 28mm adjustment range accommodates various wall thicknesses.

Available connections include PEX, PEX expansion, and NPT/welded. This flexibility suits different plumbing systems found in Canadian homes. The 1/2-inch NPT connection is compatible with standard shower trim kits.

Compatibility

The R-PB23-N is designed for use with TENZO PRO trim kits. The temperature cartridge (CAR-HY-PB-JH04BD) and diverter cartridges are sold separately with trims. This modular design allows homeowners to choose their preferred trim style while using the same rough-in valve.

The valve is compatible with both exposed and concealed shower systems. The concealed design keeps the valve body behind the wall, creating a clean appearance. The trim mounts on the wall surface, providing the visible controls.

Why Choose TENZO PRO for Canadian Homes

Canadian plumbing codes require pressure balanced valves for new shower installations. The R-PB23-N meets these requirements with CSA certification. The high flow rate accommodates Canadian households with multiple fixtures. The adjustable temperature limiter provides an extra safety measure.

The valve is built with solid brass construction for durability. Brass resists corrosion and maintains structural integrity in humid bathroom conditions. The valve is designed for Canadian residential use, with 1/2-inch NPT connections that fit standard plumbing.

What is a pressure balanced rough-in valve? 
A pressure balanced rough-in valve is the concealed valve body installed behind the wall. It monitors hot and cold water pressure and adjusts the mix to maintain consistent temperature. The rough-in valve is installed before the wall is finished, and the trim mounts on the wall surface.

What is the difference between 2 and 3 function valves? 
Two function valves typically operate two outlets, such as a rain shower head and a handheld shower. Three function valves add a third outlet, such as body jets or a tub spout. The R-PB23-N supports both configurations with different diverter cartridges.

What is the flow rate of this valve? 
The R-PB23-N delivers 25.5L/min (6.7 GPM) at 60psi. This high flow rate supports multiple outlets simultaneously without significant pressure loss. Actual flow may vary based on your home’s water pressure and plumbing configuration.

What connections are available?
Available connections include PEX, PEX expansion, and NPT/welded. This flexibility suits different plumbing systems found in Canadian homes. The 1/2-inch NPT connection is compatible with standard shower trim kits.

What is included with this rough-in valve? 
The valve includes the pressure balanced body, test cap, and installation hardware. The temperature cartridge and diverter cartridges are sold separately with the trim.

Is this valve compatible with TENZO PRO trims? 
Yes. The R-PB23-N is designed for use with TENZO PRO trim kits. The temperature cartridge (CAR-HY-PB-JH04BD) and diverter cartridges are included with the trims.

Care and Maintenance

The pressure balanced valve requires minimal maintenance. The integrated check-stop valves allow service without shutting off the main water supply. The test cap enables pressure testing during installation. If issues arise, replacement cartridges are available through TENZO PRO dealers.
