Removing the Old Bathtub Drain Plug

Before installing a new drain plug, the existing one must be carefully removed. The method depends on the type of drain plug installed, which can vary widely. Common types include lift-and-turn, push-and-pull, toe-touch, and trip lever plugs.

Start by inspecting the drain plug to identify its mechanism. Some plugs have a visible screw on top that secures the stopper to the drain body. Others may require unscrewing the drain flange or removing a set screw beneath the stopper.

To remove the old plug, follow these steps:

  • Lift-and-Turn or Push-and-Pull Plugs: Locate the small set screw on the side of the stopper. Use a flathead or Allen wrench to loosen this screw, then pull the stopper straight out.
  • Toe-Touch Plugs: These often unscrew by turning the stopper counterclockwise. Grip the stopper firmly and twist until it loosens.
  • Trip Lever Drains: Remove the trip lever assembly by unscrewing the faceplate. Then, unscrew the drain flange using a drain wrench or adjustable pliers.

If the stopper is stuck due to corrosion or buildup, apply a penetrating lubricant and allow it to sit for several minutes before attempting removal. Avoid excessive force to prevent damaging the drainpipe or bathtub surface.

Cleaning and Preparing the Drain Area

Once the old drain plug is removed, it is essential to clean the drain area thoroughly to ensure a proper seal for the new plug.

Begin by removing any debris, hair, or soap scum from the drain opening. Use a wire brush or an old toothbrush to scrub the drain flange and surrounding area.

Next, inspect the drain flange for damage or corrosion. If the flange is cracked or heavily corroded, it should be replaced to prevent leaks.

After cleaning, dry the area completely. This prevents moisture from interfering with the sealant or plumber’s putty used during installation.

Before proceeding, check the fit of the new drain plug by placing it into the drain opening. This helps confirm that the size and type are compatible.

Installing the New Bathtub Drain Plug

Installing a new drain plug involves several precise steps to ensure a watertight seal and functional operation.

  • Apply Plumber’s Putty or Silicone Sealant: Roll a small amount of plumber’s putty into a rope and place it around the underside of the new drain flange. Alternatively, use a high-quality silicone sealant designed for plumbing fixtures.
  • Insert the Drain Flange: Carefully place the flange into the drain opening, pressing firmly to create a seal with the plumber’s putty or sealant.
  • Secure the Drain Body: From beneath the tub, screw the drain body onto the flange. Use a drain wrench or adjustable pliers to tighten the connection. Ensure it is snug but avoid overtightening, which can crack the tub or strip threads.
  • Attach the Stopper Mechanism: Depending on the type of drain plug, attach the stopper by securing the set screw or threading the stopper into place.
  • Test the Drain Plug: Fill the bathtub partially with water and engage the drain plug to check for proper sealing and drainage. Look underneath for any signs of leaks.
Drain Plug Type Installation Tips Common Issues to Watch For
Lift-and-Turn Align stopper and tighten set screw securely. Loose set screw may cause stopper to spin without sealing.
Push-and-Pull Ensure stopper slides smoothly and seals tightly. Dirt buildup can cause sticking or improper sealing.
Toe-Touch Thread stopper fully and check ease of operation. Overtightening can strip threads or damage stopper.
Trip Lever Attach lever assembly securely and test drain lever function. Misaligned linkage can prevent proper stopper movement.

Troubleshooting Common Drain Plug Problems

Even after installation, some issues may arise with bathtub drain plugs. Addressing these promptly helps maintain functionality and prevent water damage.

  • Plug Does Not Seal Properly: This can be caused by improper alignment, worn rubber gaskets, or debris under the stopper. Clean the stopper and drain flange, inspect gaskets, and reposition the stopper as needed.
  • Stopper is Difficult to Operate: Mineral buildup or corrosion may cause stiffness. Remove the stopper, clean all parts with vinegar or a mild descaling solution, and lubricate moving components with a silicone-based lubricant.
  • Leaks Underneath the Tub: Check the tightness of the drain body and ensure plumber’s putty or sealant has been properly applied. Re-tighten connections if necessary and replace damaged seals.
  • Stopper Spins Without Lifting: Typically caused by a loose or missing set screw. Tighten or replace the set screw to secure the stopper to the shaft.

Regular maintenance, such as cleaning the drain and stopper monthly, can prevent many common problems and extend the life of the drain plug assembly.

Identifying the Type of Bathtub Drain Plug

Before proceeding with changing the bathtub drain plug, it is essential to identify the type of drain assembly installed in your tub. Different types of plugs require specific tools and replacement parts.

Common types of bathtub drain plugs include:

  • Lift-and-Turn: This plug lifts and turns to open or close the drain. It typically has a small knob on top.
  • Push-and-Pull: Functions by pushing down to close and pulling up to open the drain.
  • Toe-Touch: Operated by pressing the plug with a toe to open or close the drain.
  • Trip Lever: Uses an external lever on the overflow plate to open and close the drain.
  • Flip-It: Features a toggle mechanism that flips the stopper open or closed.

Determining the plug type ensures you purchase the correct replacement and understand the mechanism for removal and installation.
