This guide provides a detailed breakdown of the installation process, based on official manufacturer instructions and technical documentation. The instructions cover the removal of existing fixtures, installation of the shower mount, connection of the hose and hand shower, and considerations for backflow protection and diverter valve setup. The content is derived exclusively from official installation manuals and verified technical resources, ensuring accuracy for U.S. users seeking a reliable shower system upgrade.
Overview of Delta 75740 ProClean Chrome Shower Head
The Delta 75740 is a dual-function shower system that includes a fixed showerhead and a handheld unit. The design allows users to alternate between overhead and handheld water delivery, offering versatility for different showering preferences. The system requires a compatible diverter valve to enable switching between the two spray modes. The installation process involves replacing existing shower components and ensuring compatibility with the user's plumbing setup.
Before beginning installation, users must verify the compatibility of their existing shower arm. If the shower arm features a ball at the end, it is not suitable for this model and must be replaced with a standard shower arm. The installation instructions emphasize the use of plumber's tape on exposed threads to ensure a secure and leak-free connection. Users are advised to avoid using tools such as wrenches or pliers during installation to prevent damage to the components.
Step-by-Step Installation Instructions
The installation process for the Delta 75740 involves several key steps, including the removal of the existing showerhead, installation of the shower mount, and connection of the handheld unit. The following section outlines each step in detail, based on the manufacturer's technical documentation.
Removing the Existing Showerhead
The first step in the installation process is to remove the existing showerhead. This should be done carefully to avoid damaging the shower arm. Users are instructed to turn the existing showerhead counterclockwise using an adjustable wrench or pliers. It is important to hold the shower arm in place to prevent it from unscrewing during this process.
If the existing shower arm has a ball at the end, it is not compatible with the Delta 75740 and must be replaced. Users are advised to install a standard shower arm before proceeding with the installation of the new system. This ensures proper alignment and functionality of the new components.
Installing the Shower Mount
Once the existing showerhead has been removed, the next step is to install the shower mount. This component is responsible for holding the handheld shower in place and allowing users to adjust its position. To install the shower mount, users should wrap plumber's tape around the threads of the shower arm. The manufacturer recommends using 2–3 wraps to ensure a secure connection.
The threaded end of the shower mount should then be hand-tightened onto the shower arm in a clockwise direction. It is important not to use a wrench or pliers during this step, as excessive force can damage the threads or the mounting bracket. Once the mount is securely in place, the handheld shower can be connected.
Connecting the Hose to the Handheld Shower
After the shower mount has been installed, the next step is to connect the hose to the handheld shower. This process involves seating the washer firmly into the hose nut and aligning the threads of the hose with the hand shower. Users are instructed to hand-tighten the connection without the use of tools. Once the hose is securely attached, the handheld shower can be placed into the shower mount.
The final step in this phase involves adjusting the shower mount to the desired position. This allows users to customize the placement of the handheld shower for optimal use. The manufacturer emphasizes the importance of proper alignment to ensure smooth operation and prevent water leakage.
Diverter Valve and System Configuration
In addition to the physical installation of the showerhead and handheld unit, users must also configure the diverter valve to enable switching between the two spray modes. The diverter is a critical component of the Delta shower system, allowing users to direct water flow to either the overhead showerhead or the handheld unit.
The diverter valve is typically part of the rough-in valve system and features three ports: one inlet port and two outlet ports. The inlet port receives the mixed water from the hot and cold supply lines, while the outlet ports direct the water to the showerhead and handheld unit. In the case of the Delta 75740, only two of the outlet ports will be used, with the third port being capped off.
Installation of the Diverter Valve
The installation of the diverter valve requires careful planning and attention to detail. Users are advised to consult the manufacturer's installation guide to ensure proper configuration. The rough valve installation does not determine the function of the system, but it plays a crucial role in directing water flow.
To install the diverter, users must first apply plumber's tape to the threaded ends of the 1/2-inch iron pipe nipple. The nipple is then threaded into the shower riser elbow, ensuring that it extends past the finished wall by no more than 1/2 inch and no less than 1/4 inch. A gasket should be placed behind the elbow to provide a watertight seal.
The supplied installation tool is then threaded onto the base of the elbow to provide additional leverage during the installation process. A 1/4-inch Allen wrench is used to tighten the supply elbow onto the nipple, ensuring that the outlet is facing downward. Once the installation is complete, the tool should be removed and the system tested for leaks.
Placement and Suggested Measurements
Proper placement of the diverter and other components is essential for optimal performance and user convenience. Delta provides recommended measurements for various components to ensure a functional and ergonomic setup.
For the hand shower mounting bracket, Delta suggests a height range of 72 to 84 inches from the floor. This allows for easy reach and flexibility, especially for users of varying heights. If the hand shower includes a slidebar, the top bracket should be installed at approximately the same height to allow for vertical adjustment.
The center of the mixing valve control handle should be placed at waist height, approximately 36 inches from the bottom of the shower enclosure. If a tub spout is installed, the control should be positioned 8 to 18 inches above the spout. These measurements ensure that users can easily access and adjust the temperature and flow settings.
Backflow Protection and Warranty Considerations
One important consideration for Delta shower system users is backflow protection. The Delta 75740 does not include a built-in backflow prevention device, which means users may need to install a separate vacuum breaker if local plumbing codes require it. This is particularly important in areas with strict water safety regulations.
Users are also advised to avoid removing or tampering with the flow restrictor, as this can lead to system failure and void the warranty. The manufacturer explicitly states that any unauthorized modifications to the internal components may result in a loss of warranty coverage.
Delta offers a lifetime warranty on all its fixtures, which reflects the company's commitment to quality and customer satisfaction. This warranty covers defects in materials and workmanship, providing users with peace of mind. For additional support, users can contact Delta's customer service team for assistance with installation, troubleshooting, or replacement parts.
Additional Installation Tips
While the installation process for the Delta 75740 is generally straightforward, there are several best practices that users should follow to ensure a successful installation. These include:
- Double-checking all measurements before drilling holes for mounting brackets or installing components.
- Ensuring that all threaded connections are properly sealed with plumber's tape.
- Avoiding the use of tools such as wrenches or pliers during installation to prevent damage.
- Testing the system for leaks after installation and making any necessary adjustments.
For users who are unsure about the installation process or encounter difficulties, it is advisable to consult a professional plumber or licensed contractor. This can help ensure that the system is installed correctly and functions as intended.
