How to Fix a Sink Drain Stopper

Quick answer

To fix a sink drain stopper, first identify if it's a pop-up or lift-and-turn type. For pop-up stoppers, check for debris or a broken rod. For lift-and-turn stoppers, ensure the pivot rod is properly aligned. Always turn off the water supply before starting any repairs.

• Water drains slowly or not at all when the stopper is engaged.
• Stopper does not stay in place when engaged.
• Stopper is difficult to lift or turn.
• Water leaks around the stopper when the sink is filled.
• Stopper is missing or broken.

Tools and prep

• Screwdrivers (flathead and Phillips)
• Pliers
• Channel-lock pliers

• Towels to soak up water
• Turn off water supply to the sink
• Place a bucket under the sink to catch water
