Turn off the water supply valves under the sink to prevent accidental leaks.
Place a bucket directly under the P-trap to catch any residual water.
Use an adjustable wrench or your hands to loosen the slip nuts on both ends of the P-trap.
Carefully remove the P-trap and pour any water inside into the bucket.
Inspect the washers and seals for cracks, wear, or misalignment.
Check the P-trap itself for cracks or corrosion that could cause leaks.
Replace any damaged washers or the entire P-trap if necessary.
Wrap plumber's tape around the threaded connections if they appear worn or loose.
Reinstall the P-trap by aligning it with the drain pipe and tailpiece.
Hand-tighten the slip nuts securely, ensuring the washers are seated properly.
Turn the water supply back on slowly and check for any leaks.
Run water through the sink for a few minutes while observing the P-trap area.
If leaks are present, slightly tighten the slip nuts with a wrench without over-tightening.
Ensure the P-trap is aligned correctly and not under stress from misaligned pipes.
Wipe down the area with a towel or rag to remove any spilled water.
Use a flashlight to double-check for slow drips or hidden leaks.
If leaks persist, disassemble and recheck washer placement and pipe alignment.
Apply plumber's putty around joints if needed for a better seal.
Once leak-free, remove the bucket and clean up the workspace.
Dispose of any old parts and dry the area thoroughly to prevent mold.
