These assemblies feature a stopper that is pushed down to seal the drain and pushed again to release it. Delta push-and-seal drain assemblies are known for their ease of use and streamlined design. They are often available in a variety of finishes to complement contemporary bathroom styles.

Cable-Operated Drain Assemblies: Cable-operated drain assemblies use a cable to connect the overflow lever to the drain stopper. This type of drain assembly is suitable for bathtubs with more complex plumbing configurations or when the overflow is located at a distance from the drain. Delta cable-operated drain assemblies offer flexibility and reliability, even in challenging installation environments.

Components of a Delta Bathtub Drain Assembly

Regardless of the specific type, a typical Delta bathtub drain assembly consists of several key components that work together to ensure proper drainage and prevent leaks. Familiarity with these components is essential for installation, troubleshooting, and maintenance.

Drain Flange: The drain flange is the visible metal ring that sits flush with the bathtub's drain opening. It provides a secure connection point for the drain assembly and prevents water from leaking between the tub and the drain. Delta drain flanges are typically made from brass or stainless steel and are available in various finishes.

Drain Body: The drain body is the main housing of the drain assembly, connecting the drain flange to the drainpipe. It typically includes internal threads for securing the drain flange and a threaded outlet for connecting to the waste and overflow pipe. Delta drain bodies are designed for durability and corrosion resistance.

Stopper: The stopper is the component that seals the drain opening to prevent water from escaping. The design of the stopper varies depending on the type of drain assembly. Pop-up drains have a plunger-style stopper, while lift-and-turn drains have a stopper that is manually lifted and turned. Toe-touch and push-and-seal drains feature a specialized stopper mechanism.

Overflow Plate and Lever: The overflow plate is a decorative cover located near the top of the bathtub that conceals the overflow pipe. The overflow lever, which is attached to the overflow plate, controls the drain stopper in pop-up drain assemblies. Delta overflow plates and levers are available in a variety of finishes to match the bathroom's decor.

Waste and Overflow Pipe: The waste and overflow (W&O) pipe is a crucial component that connects the bathtub drain to the main drainpipe. It allows excess water to drain when the bathtub is overfilled, preventing overflows and potential water damage. Delta W&O pipes are typically made from PVC or brass and are designed for efficient drainage.

Gaskets and Washers: Gaskets and washers are used to create watertight seals between the different components of the drain assembly. These components are essential for preventing leaks and ensuring proper drainage. Delta drain assemblies typically include high-quality gaskets and washers made from rubber or silicone.

Installing a Delta Bathtub Drain Assembly

Installing a Delta bathtub drain assembly correctly is crucial for ensuring its proper function and preventing leaks. While professional installation is always recommended, a homeowner with intermediate plumbing skills can often complete the installation process by following these steps:

Preparation: Before beginning the installation, gather all necessary tools and materials, including a pipe wrench, adjustable wrench, screwdriver, plumber's putty, Teflon tape, and the new Delta bathtub drain assembly. Ensure the water supply to the bathroom is turned off.

Removing the Old Drain Assembly: Carefully remove the old drain assembly by loosening the drain flange with a pipe wrench or adjustable wrench. Disconnect the waste and overflow pipe from the drain body. Clean the drain opening thoroughly to remove any debris or old plumber's putty.

Preparing the Drain Flange: Apply a generous amount of plumber's putty to the underside of the new drain flange. This will create a watertight seal between the flange and the bathtub. Ensure the putty is evenly distributed around the flange.

Installing the Drain Flange: Insert the new drain flange into the drain opening, pressing firmly to ensure the plumber's putty makes good contact with the bathtub surface. From underneath the tub, attach the drain body to the drain flange, tightening it securely with a wrench. Remove any excess plumber's putty from around the flange.

Connecting the Waste and Overflow Pipe: Attach the waste and overflow pipe to the drain body, ensuring all connections are tight and secure. Use Teflon tape on the threaded connections to prevent leaks. If necessary, adjust the length of the waste and overflow pipe to fit the specific plumbing configuration.

Installing the Overflow Plate and Lever: Install the overflow plate and lever, connecting the lever to the drain stopper mechanism. Ensure the lever operates smoothly and the stopper seals the drain effectively. Secure the overflow plate to the bathtub with screws.

Testing for Leaks: After completing the installation, turn the water supply back on and fill the bathtub with water. Check for leaks around the drain flange, waste and overflow pipe, and overflow plate. If any leaks are detected, tighten the connections or reapply plumber's putty or Teflon tape as needed.

Common Issues with Delta Bathtub Drain Assemblies

Even with proper installation and maintenance, Delta bathtub drain assemblies can sometimes experience issues that affect their performance. Being aware of these common problems can help in troubleshooting and resolving them effectively.

Slow Drainage: Slow drainage is a common issue that can be caused by hair, soap scum, or other debris clogging the drainpipe. To resolve this, use a drain snake or plunger to clear the blockage. Regularly cleaning the drain with a drain cleaner can also help prevent clogs.
