How to clean a P-trap in my kitchen sink?

 
Preliminary Setup
 

• Gather necessary supplies: a bucket, adjustable pliers, an old toothbrush or scrubbing brush, a wrench (if needed), cloth or paper towels, protective gloves, and a cleaning solution (such as baking soda and vinegar).
• Clear the area under the sink to have enough space and lay down old towels or a bucket to catch any spilled water.
• Understand the layout of your P-trap. It is the curved pipe connecting the sink drain to the rest of the plumbing system.

 
Many property owners in St. Louis and Nashville find these steps effective for routine plumbing maintenance.
 
Clearing Out the P-trap
 

• Place a bucket or container directly underneath the P-trap to catch water and debris.
• If the P-trap has slip nuts securing it, use your pliers to loosen these; if the nuts turn easily by hand, loosen them manually.
• Remove the P-trap carefully. It may be slightly heavy and full of water, so tilt it slowly to allow the water to drain into the bucket.

 
Cleaning the P-trap
 

• Empty the contents of the P-trap into the bucket and inspect for any blockages or accumulated grime.
• Using an old toothbrush or scrubbing brush, scrub the inside and outside of the trap. Apply a mixture of baking soda and vinegar or a mild detergent to break down grease and remove buildup.
• Allow the cleaning mixture to work for 5–10 minutes before scrubbing vigorously.
• Rinse thoroughly with running water to ensure that all debris and cleaning solution are washed away.

 
Reassembling the P-trap
 

• Inspect the trap's rubber gaskets or washers. Replace if there are signs of wear to prevent future leaks.
• Reattach the P-trap by aligning the slip nuts and tightening them by hand initially. Use pliers if necessary to ensure a secure fit, but avoid overtightening to prevent damaging the joints.
• Double-check that all connections are secure and the trap is properly aligned.

 
Final Inspection and Testing
 

• Turn on the water to check for leaks. Make sure all joints are dry and no water is escaping.
• If leaks are detected, tighten connections slightly and test again until the leak is resolved.
• Clean up the working area and dispose of any waste or used cleaning materials responsibly.
