The Delta R10000 Series Multichoice Universal Shower Valve is a versatile and durable solution designed for use in a wide range of bathroom configurations. As a rough-in valve, it serves as the foundational component of a shower system, allowing for the installation of various Delta-branded trim assemblies. This article provides a detailed technical overview and step-by-step installation guidance based on official documentation and instructions from Delta Faucet Company.
Understanding the installation requirements and specifications of this product is essential for ensuring safe, functional, and code-compliant installation. The following sections outline key components, installation procedures, and maintenance considerations, all grounded in the information provided by Delta Faucet.
Key Components and Technical Specifications
The Delta R10000 Series Multichoice Universal Shower Valve is a pressure-balanced system that regulates water flow and temperature to prevent scalding or sudden temperature changes. The valve is designed for installation behind the finished wall and connects to the hot and cold water supplies via standard plumbing methods. The installation process involves positioning the valve body, connecting the water supply lines, and ensuring the proper alignment with the finished wall.
The valve body includes a plasterguard, which is a protective shield that helps maintain the valve in alignment with the finished wall surface. The distance between the stringer (a structural component of the valve body) and the front of the plasterguard is specified as 2 3/4 inches ± 1/4 inch (70 mm ± 6 mm). This measurement is also the same as the distance from the stringer to the finished wall. Additionally, the distance from the stringer to the front of the bonnet is 3 7/8 inches (99 mm).
The valve is compatible with multiple types of piping materials, including copper tubing, iron pipe, and PEX (cross-linked polyethylene). When using PEX, it is important to use the appropriate fittings for crimping and cold expansion. If one of the two outlet ports is not being used, it should be sealed with a pipe plug.
For installations where the finished wall is thinner than standard, special mounting considerations are required. In such cases, the RP47202 mounting bracket may be necessary to ensure proper alignment and support.
Installation Preparation and Setup
Before beginning installation, it is essential to shut off the water supply to the area where the valve is being installed. This step is critical to prevent water damage and to ensure a safe working environment. The installation instructions emphasize the importance of reading all provided materials prior to starting the process, as failure to do so may result in personal injury, property damage, or product failure.
The first step in installation involves positioning the valve body (1) so that the surface of the finished wall is flush with the front of the plasterguard (2) ± 1/4 inch. This ensures that the finished wall will align correctly with the trim and that the valve will function as intended. For models that include a stop mechanism, the plasterguard must be flush or subflush by 1/4 inch to the finished wall.
The valve body should be mounted using the two stringer mounting holes (3) on the bracket. It is important to remove the cover (4) to access the mounting holes during installation. The word “UP” (5) must be oriented to the top of the valve body to ensure correct orientation.
Connecting Water Supply Lines
Once the valve body is properly positioned, the next step is to connect the valve to the water supply lines. The valve includes two inlet ports: (1) is the cold inlet port, and (2) is the hot inlet port. These ports should be connected using the appropriate fittings based on the type of piping material being used—copper tubing, iron pipe, or PEX.
For PEX connections, it is important to use the correct type of fitting and tool. Specifically, the fitting must be compatible with the type of PEX being used, and the tool must be suitable for either crimping or cold expansion, depending on the fitting type. Failure to use the correct tools and fittings may result in leaks or improper connections.
If one of the outlet ports is not being used, it must be sealed with a pipe plug. This prevents water from escaping and ensures that the pressure within the system remains balanced.
Reverse or Back-to-Back Installation
In some installations, it may be necessary to perform a reverse or back-to-back installation, where the hot and cold water supplies are reversed. This type of installation requires careful attention to the orientation of the valve body and the water supply lines.
When installing in a reverse configuration, the hot inlet port (1) and cold inlet port (2) must be connected accordingly. The valve body should be installed as described, but the water supply lines will be reversed. It is important to verify the correct orientation of the ports and ensure that the valve is installed with the word “UP” (5) facing the top of the valve body.
Assembly and Adjustment
After the valve body is installed and the water supply lines are connected, the next step involves assembling the stem and nut assembly. The thread nut (6) should be threaded onto the stem (7) as shown in the installation guide. The stem and nut assembly should then be pressed into the body (8) and tightened using a 3/8-inch, 6-point, deep well socket.
Once the stem is in place, it can be adjusted using a flat head screwdriver. Turning the stem clockwise will close the valve, while turning it counterclockwise will open the valve. This adjustment is used to fine-tune the valve’s operation and ensure that it functions correctly with the intended trim assembly.
Safety and Warning Considerations
During the installation process, several safety precautions should be taken to avoid damage to the valve or injury to the installer. One such precaution involves avoiding high-temperature soldering, as this can damage the internal components of the valve, particularly the screen (3). It is recommended to keep the temperature as low as possible during soldering to prevent such issues.
Additionally, if the valve is a model that includes stops (4), these should be removed before soldering. Installing the stops before soldering may result in damage or improper function of the valve. It is also important to remove the bonnet (1) and test cap (2) before soldering, while the screen (3) should remain installed to protect the internal components.
Maintenance and Cleaning
Once the valve is installed and operational, regular maintenance is not typically required, as the system is designed for durability and long-term use. However, if cleaning is necessary, it should be done with care to avoid damaging the finish.
The finish on the valve is extremely durable, but it can be compromised by harsh abrasives or polish. To clean the valve, it is recommended to use a damp cloth to gently wipe the surface and then blot it dry with a soft towel. This method is effective in removing dirt and grime without causing any harm to the finish.
