Removing the Drain Stopper

The first step in disassembling a bathtub drain is to remove the drain stopper, which typically prevents water from flowing out of the tub. The type of stopper installed will determine the removal process. Common types include lift-and-turn, push-and-pull, toe-touch, and trip lever stoppers.

For lift-and-turn and push-and-pull stoppers, locate the small set screw on the side of the stopper’s knob. Using a suitable screwdriver or Allen wrench, loosen this screw without fully removing it. Then, twist or pull the stopper upward to remove it from the drain body.

Toe-touch stoppers usually require a firm pull upward after loosening any visible screws, while trip lever stoppers are connected to a linkage mechanism operated by a lever on the tub’s overflow plate. In this case, you will need to remove the overflow plate to access the linkage and disconnect it before removing the stopper.

If the stopper is corroded or stuck, applying a lubricant such as penetrating oil around the base can help loosen it. Be sure to wipe away any debris to prevent it from entering the drain.

Unscrewing the Drain Flange

Once the stopper is removed, the drain flange—the visible ring inside the tub drain—can be unscrewed. This flange connects to the drain pipe and often requires a specialized tool known as a drain wrench or a pair of adjustable pliers.

To proceed:

  • Insert the drain wrench into the flange, ensuring it grips the crossbars inside.
  • Turn the wrench counterclockwise to loosen the flange.
  • If a wrench is not available, locking pliers can be used to grip the flange tightly and turn it.
  • For stubborn flanges, applying a lubricant around the threads can aid in loosening.

Be cautious not to damage the tub surface or the flange threads during removal. If the flange is sealed with plumber’s putty or caulking, gently scrape around the edges to break the seal before unscrewing.

Disconnecting the Drain Pipe

After removing the flange, the drain pipe underneath the tub will be exposed. This pipe connects the bathtub drain to the home’s main drainage system.

Steps for disconnection include:

  • Inspect the pipe connection. If it uses a threaded coupling, grip the coupling with adjustable pliers or a pipe wrench and turn counterclockwise.
  • For slip joint connections, locate the slip nut and loosen it by hand or with pliers.
  • In some cases, PVC pipes may be glued; these require cutting the pipe with a hacksaw or reciprocating saw. Ensure you have a replacement pipe and fittings ready before cutting.
  • Place a bucket or towels beneath the pipe to catch any residual water.

Once disconnected, the drain assembly components can be fully removed for cleaning, repair, or replacement.

Identifying the Drain Type

Understanding the type of drain installed is critical for selecting the proper disassembly method. Bathtub drains typically fall into one of the following categories:

Drain Type Description Common Disassembly Method
Trip Lever Drain Features a lever on the overflow plate that raises and lowers the drain stopper. Remove overflow plate and lever assembly; unscrew drain flange with a drain wrench.
Push-Pull Drain Stopper is lifted or pushed down manually to open or close the drain. Unscrew the stopper by hand or with pliers; remove flange as needed.
Lift-and-Turn Drain Stopper is lifted and turned to open or close. Unscrew stopper by rotating counterclockwise; then remove flange.
Toe-Touch Drain Operated by pressing the stopper with a toe to open or close. Unscrew stopper by hand or with pliers; remove flange.

Step-by-Step Process to Disassemble the Bathtub Drain

Follow these detailed steps to safely and efficiently disassemble a standard bathtub drain:

  1. Remove the Stopper:
    Depending on the drain type, the stopper may need to be unscrewed or detached. For screw-in stoppers (lift-and-turn or toe-touch), rotate counterclockwise. For push-pull stoppers, pull firmly upward or unscrew if threaded.

  2. Detach the Overflow Plate and Trip Lever (if applicable):
    Use a screwdriver to remove the screws securing the overflow plate. Carefully pull the plate away from the wall, extracting the trip lever assembly.

  3. Loosen the Drain Flange:
    Insert a drain wrench into the crossbars inside the drain flange. Turn counterclockwise to unscrew. If no drain wrench is available, adjustable pliers can be used cautiously to avoid damage.
