Fixing a Leaking Sink Drain

Causes of a Sink Drain Leak

  • Worn or cracked rubber gasket
  • Loose connection between drain and sink
  • Faulty valve
  • Blocked drain pipe

Steps to Fix a Leaking Sink Drain

Check Plumbing Connections

  • Step 1: Tighten the P-trap, tail piece, and gasket using a wrench.
  • Step 2: Ensure the sink basket’s strainer and locknut are secure by hand-tightening them.

Replace Washer or O-Ring

  • Step 1: Remove the worn washer or O-ring using a pair of pliers.
  • Step 2: Place a new washer or O-ring onto the bolt.
  • Step 3: Tighten the nut using a wrench.

Tighten or Replace the Trap

  • Step 1: Check if the trap connections are tight by hand-tightening them.
  • Step 2: If the trap is still leaking, you may need to replace it. To do this, loosen the nuts that connect the trap to the drain and sink, and remove the old trap. Install the new trap and tighten the nuts.

Preventive Maintenance

  • Step 1: Clean the drain periodically with a mixture of vinegar and baking soda. To do this, pour 1/2 cup of baking soda down the drain, followed by 1/2 cup of vinegar. Let the mixture sit for 15 minutes, then flush the drain with hot water.
  • Step 2: Use a mesh strainer to catch hair and debris before it even makes it down the drain.
  • Step 3: Avoid pouring grease or oil down the drain, as this can clog the pipes.
