Steps

1. Step 1: Prepare the area

   • Clear items from under the sink.
   • Turn off the faucet.
   • Place towels under the sink and set a bucket below the trap.
   • If there is standing water in the sink, remove some with a cup or container so it will not splash easily.

   Check: The cabinet area is clear and protected. · A bucket is positioned under the trap. · Water will not spill excessively when you begin.

2. Step 2: Remove visible debris from the drain opening

   • Put on gloves.
   • Take out the sink strainer or stopper if present.
   • Pull out any visible food debris or buildup from the drain opening.
   • Run a small amount of hot water to see if the blockage was near the top.

   Check: The drain opening is free of obvious debris. · Water either drains better or confirms the clog is deeper.

3. Step 3: Plunge the sink

   • Add enough water to cover the plunger cup.
   • If you have a double sink, seal the other drain opening with a wet cloth or stopper.
   • Place the plunger firmly over the clogged drain.
   • Push and pull with a few firm, controlled strokes, then lift the plunger and check drainage.
   • Repeat several times if needed.

   Check: The plunger maintains a seal over the drain. · Water begins to drain faster or the water level drops after plunging.

4. Step 4: Flush with hot water and dish soap

   • Pour a little dish soap into the drain.
   • Follow with hot water in stages, not all at once.
   • Wait a minute and observe the drain speed.

   Check: Water drains steadily without backing up quickly. · There is no leaking under the sink.

5. Step 5: Clean the trap if the sink is still clogged

   • Keep the bucket directly under the curved trap.
   • Use adjustable pliers if needed to loosen the slip nuts carefully.
   • Remove the trap and let water and debris empty into the bucket.
   • Clear out any blockage inside the trap.
   • Reattach the trap securely by hand, tightening gently with pliers only if needed.

   Check: Debris was removed from the trap. · The trap is reinstalled evenly and feels secure. · No water leaks from the fittings when tested.

6. Step 6: Test and finish

   • Run warm water for 30 to 60 seconds.
   • Check underneath the sink for leaks at the trap connections.
   • Wipe up the area and put items back under the sink only after confirming it stays dry.

   Check: The sink drains normally. · No drips or leaks appear under the sink. · The work area is clean and dry.
