How to remove an old pop-up drain stopper from a bathroom sink?

 
Preparation and Gathering Tools
 

• Collect necessary tools such as a flathead screwdriver, pliers (slip-joint or channel-lock type), and a flashlight.
• Have a bucket or container nearby for catching any water or small parts that might drop.
• Wear gloves to protect your hands from sharp edges or rust.

 
Clearing the Work Area
 

• Move any items stored under the bathroom sink to ensure you have clear access to the drain assembly.
• Place towels or a drop cloth on the floor to safeguard against spills.

 
Inspecting the Drain Mechanism
 

• Examine the top of the sink where the pop-up stopper is visible. Most stoppers are connected to a pull rod and a linkage system.
• Determine whether your stopper is a lift-and-turn design or a twist-to-open type. This will affect the removal method.
• Look underneath the sink to identify the pivot nut or screw that holds the stopper’s linkage to the drainpipe.

 
Disconnecting the Linkage Under the Sink
 

• Position your flashlight under the sink and locate the horizontal rod (linkage) that connects the drain stopper to the pivot mechanism.
• If there is a retaining clip or nut securing the linkage, use your pliers or screwdriver to loosen or remove it carefully.
• Take note of the order and orientation of any parts before removal to ease reassembly if necessary.

 
Removing the Pop-Up Stopper from the Sink
 

• With the linkage detached or loosened, try raising the stopper from the sink; you may need to twist it slightly to disengage any locks.
• If the stopper resists, gently wiggle it back and forth while applying upward pressure. In some setups, it might require a slight rotation to release from the drain’s internal catch.
• Once freed, pull the stopper straight out, being careful not to damage the sink’s surface or the drain assembly.

 
Cleaning and Inspecting the Drain Assembly
 

• Check the drain opening for any buildup of debris, corrosion, or residual water that might cause issues later.
• Clean the surfaces with a mild cleaner and scrub gently if necessary.
• Inspect the linkage and pivot hardware for signs of wear or rust that might require replacement.

 
Final Steps and Considerations
 

• If you plan to install a new stopper, compare the old parts with the new ones to ensure compatibility.
• Follow the installation instructions for the new stopper carefully, ensuring that the linkage is reconnected correctly and that the pivot mechanism functions smoothly.
• Test the stopper’s operation by filling the sink with water and engaging the pop-up function repeatedly to confirm there are no leaks or mechanical issues.
• These instructions are applicable for both residential and commercial settings, including for those in St. Louis and Nashville.
