Installing a Westbrass tub drain may seem like a task best left to a licensed plumber, but with the right tools and a methodical approach, it becomes a manageable weekend project. This guide walks you through the process, focusing on the specific requirements and design nuances of Westbrass components to ensure a watertight seal and long-term functionality. Replacing an old, leaky drain is one of the most effective ways to update the look and performance of your bathtub without a full remodel.
Westbrass is renowned for its commitment to quality materials and classic design aesthetics, often featuring durable chrome finishes and robust brass construction. Their tub drains are engineered to withstand daily use, but proper installation is critical to realizing their full lifespan. A failed seal not only causes water damage to your subfloor but can also create an unsightly mess around the base of your tub. Understanding the specific components—such as the rubber gasket, the locking nut, and the waste assembly—is the first step to a successful install.
Tools and Materials You Will Need
Before you begin, gather all necessary tools to avoid mid-project trips to the hardware store. Having everything at arm's length ensures you maintain focus and efficiency throughout the installation process. Missing a simple tool like a basin wrench can turn a straightforward task into a frustrating ordeal.
- Adjustable wrench or channel-lock pliers
- Screwdriver (flathead and Phillips)
- Basin wrench (specifically for reaching the underside of the tub)
- Plumber's tape (Teflon tape)
- Putty knife
- Flashlight
- Bucket or towel
Removing the Old Drain Assembly
Safety and preparation are paramount before diving into the removal stage. Start by turning off the water supply to the bathroom, or at least ensure the tub is empty to prevent water from rushing down the pipes as you work. Place your bucket or towel on the floor to catch any residual water that may spill from the drain pipe.
Locate the visible locking nut that holds the Westbrass drain body in place beneath the tub. Using your basin wrench, grip the nut securely and turn it counter-clockwise to loosen it. This component is often the most stubborn part of the process due to years of mineral buildup and corrosion. Once the nut is free, carefully lift the drain body out of the hole, extracting the rubber gasket and any debris that has accumulated over time.
Preparing the Drain Hole and New GasketWith the old component removed, take a moment to inspect the drain hole in your tub. Ensure that the surface is clean and free of old plumber's putty or dried grout, as any obstruction will prevent a proper seal. Use your putty knife to scrape away any residue, and rinse the area with water if necessary, allowing it to dry completely before proceeding.
Westbrass kits usually come with a new rubber gasket designed specifically for their drains. Inspect this gasket for any defects or tears, as it is the primary barrier against leaks. Lubricate the gasket with a small amount of plumber's grease or soap to allow it to slide into place easily. This lubrication ensures that the gasket seats correctly without tearing when you tighten the components.
Installing the New Westbrass Drain
This is the core step of the installation process. Begin by inserting the new gasket into the drain hole from inside the tub. Next, thread the Westbrass drain body through the hole, ensuring the orientation is correct—the slotted or flat side should face up toward the tub floor. Screw the rubber gasket onto the drain body by hand, turning it clockwise until it is flush with the bottom of the tub surface.
Now, position the new locking nut onto the threads beneath the tub. Carefully tighten this nut by hand first, then use your basin wrench to secure it firmly. The goal is to tighten it enough to compress the gasket and create a watertight seal, but avoid overtightening, which can crack the tub's enamel or distort the metal components. Hand-tight plus a quarter-turn with the wrench is often sufficient for a secure fit.
Connecting the Waste Pipe and Final Check
With the drain body secured, you must now address the connection to the house's plumbing waste line. Depending on your setup, you will either attach the new drain's tailpiece to a P-trap or directly into a pipe in the wall. Apply a generous layer of plumber's tape to the threads of the drain's outlet to prevent future leaks. Use your adjustable wrench to screw on the coupling or tailpiece, ensuring it is tightened appropriately.
Once everything is connected, it is time for the critical final check. Slowly pour several gallons of water into the tub and observe the drain assembly closely for any signs of dripping. Check the connection points both inside the tub and under the floor for at least a minute. If no leaks are present, you have successfully installed your Westbrass tub drain. Wipe away any excess plumber's putty and restore your water supply to complete the job.
