The installation of a Delta bathtub and associated fixtures requires a thorough understanding of plumbing codes, adhesive application, and valve configuration. This guide compiles detailed information from official technical manuals and installation instructions provided by Delta for two specific models: the B14416-6032-WH Acrylic Rectangular Back Center Drain Freestanding Soaking Bathtub and the T144339-LHD-PP Modern Monitor 14 Series Tub & Shower Trim – Less Head. The information presented here is derived exclusively from manufacturer-provided documentation and is intended for use by professionals and experienced DIY users.
Installation of the Delta B14416-6032-WH Acrylic Bathtub
Pre-Installation Considerations
Before beginning installation, it is essential to review local plumbing codes. The Delta bathtub is designed to meet general standards, but compliance with local regulations is the responsibility of the installer. The installation of this freestanding soaking bathtub involves several critical steps, including positioning, leveling, and proper connection to waste piping.
Positioning and Leveling the Tub
Position the Tub: Place the tub in the desired location, ensuring it is level on the finished floor. If the floor is uneven, the tub can be adjusted using the hex nuts and threaded rods at the base. Loosening the hex nut allows the tub to be raised or lowered by adjusting the rod in or out of the wood block.
Drain Alignment: To ensure proper drainage, the toe tap drain should be unscrewed and the drain location marked. A Schedule 40 1 1/2” PVC waste pipe must be installed in accordance with local plumbing codes. It is recommended to perform a dry fit of the tub to confirm that the PVC waste pipe is seated correctly within the waste drain to prevent potential leaks.
Adhesive Application: A bead of adhesive should be applied along the bottom of the apron and legs to secure the tub to the floor. The adhesive should not be applied to the cutout area of the apron to avoid interference with drainage and to allow for proper sealing.
Adhesive and Sealant Use
Sealant Application: After positioning the tub, a bead of kitchen and bath sealant should be applied around the outside of the bathtub. This sealant serves both a functional and aesthetic purpose, ensuring watertight integrity and a finished appearance.
Paper Leak Test: To check for leaks during installation, a piece of paper can be slid underneath the apron at the waste overflow side of the tub while water is turned on. The presence of water soaking the paper indicates a leak and requires repositioning or resealing.
Faucet Installation (Optional)
The installation of a faucet requires the bathtub to be disassembled prior to installation. The faucet should be installed on the bathing well deck before reassembling the apron. Once the faucet is in place, the bathing well should be set on an elevated surface to prevent damage to the faucet. The apron must be reattached with the cutout aligned to the waste and overflow side. It is important to note that this method of installation may violate local plumbing codes, and installers should verify compliance with their jurisdiction before proceeding.

Pre-Installation Warnings and Notices
The T144339-LHD-PP model is a pressure-balanced or thermostatic tub and shower trim that requires careful installation to ensure safe and consistent water temperature. Several warnings and cautions are included in the official documentation, emphasizing the importance of proper installation and adjustment.
Key Warnings and Cautions
Hot Water Burn Risk: This valve does not automatically adjust for changes in inlet temperature or pressure. If the temperature setting of the hot water heater or inlet is altered, the valve must be manually adjusted. Failure to do so can result in hot water burns or extreme cold, particularly when other appliances (such as dishwashers or washing machines) are in use during a shower.
Labeling Requirements: Installers are required to apply specific labels to both the water heater and the valve. These labels serve as reminders for the homeowner to maintain proper settings and to inform them of the need for manual adjustments. One label must be affixed to the water heater near the temperature adjustment knob, and another should be placed inside a cabinet or vanity near the valve for visibility.
Rotational Limit Stop Adjustment: The valve includes a rotational limit stop that must be set by the installer to prevent unsafe temperature fluctuations. This setting must be verified after installation and updated if the hot water heater’s temperature is adjusted. The installer must complete a section on the caution label with their name, company name, and the date of adjustment, and this label must be affixed to the back of the closest cabinet door.
Installation and Adjustment Procedure
Shutting Off Water Supplies: Before beginning installation, ensure that both hot and cold water supplies are turned off. This is critical for safety and to prevent water damage during the installation process.
Mounting the Valve Body:
- Plasterguard Positioning: The body of the valve should be installed so that the surface of the finished wall is flush with the front of the plasterguard, with a tolerance of ± 3/8”. For models with stops, the plasterguard must be either flush or subflush by 3/8” to the finished wall.
- Bracket Mounting: The body should be mounted using the two stringer mounting holes on the bracket. The word “UP” on the valve body must be oriented correctly (on top) to ensure proper internal function.
Connecting Water Supplies:
- Connect the valve body to the water supplies using appropriate fittings (copper tubing, iron pipe, or PEX).
- The cold inlet port is labeled as (1), and the hot inlet port is labeled as (2). If either of the two outlet ports is not being used, it should be sealed with a pipe plug.
Handle and Trim Installation:
- Use an Allen wrench to secure the set screw and install the handle onto the stem. Tighten the set screw to ensure the handle is secure.
- If the model includes a plug button, insert it into the set screw hole.
- Adjust the sleeve to minimize the gap between the sleeve and the handle for a clean appearance.
Rotational Limit Stop Adjustment:
- After installation, the rotational limit stop must be adjusted according to the instructions provided. This ensures that the water temperature remains within a safe range and does not fluctuate due to changes in pressure or inlet temperature.
- The installer must complete the caution label with their information and affix it to the designated location (typically the back of a cabinet door). The warning label must also be attached to the water heater.
Verification and Final Steps:
- After installation, the water supply should be turned on, and the system should be tested for proper function and temperature control.
- The installer must inform the user of the need for potential future adjustments, especially if the water heater’s temperature setting changes.
- The instruction sheet should be left for the homeowner’s reference, and the labels must remain visible for future reference.
Warranty and Maintenance Considerations
The Delta bathtub and valve systems come with specific warranty conditions that must be followed to ensure coverage:
Bathtub Warranty: The warranty on the Delta bathtub is void if the product is damaged due to misuse, abuse, neglect, accident, improper installation, or the use of non-genuine replacement parts. Adherence to the installation instructions is essential for maintaining warranty validity.
Valve Warranty: Similarly, the valve system is not covered under warranty if the rotational limit stop or temperature knob is not adjusted correctly, or if the system is used in a manner that violates the provided instructions.
Maintenance Recommendations: Regular checks for leaks, proper sealing, and water temperature stability are recommended to ensure the longevity and safety of the installed system.
Conclusion
The installation of Delta bathtubs and trim components requires careful adherence to both manufacturer guidelines and local plumbing codes. The Delta B14416-6032-WH freestanding bathtub and the T144339-LHD-PP tub and shower trim each have specific installation requirements that must be followed to ensure functionality, safety, and compliance with warranty terms. Proper leveling, alignment, adhesive application, and valve adjustment are all critical steps in the process. Installers must also be mindful of the warnings and cautions provided, particularly regarding the manual adjustment of temperature settings and the potential for hot water burns. By following these detailed instructions, professionals and experienced DIY users can achieve a reliable and safe installation that meets both aesthetic and functional standards.
