Step 1 · Prepare Workspace and Disconnect P-Trap

Begin by clearing everything from the cabinet under the sink to give yourself ample working space. Place a bucket directly underneath the P-trap assembly to catch any residual water that will spill out when you disconnect the pipes. Using a pair of channel-lock pliers, loosen the slip nuts connecting the P-trap to the strainer's tailpiece and the wall drain pipe. Once loose, you can usually finish unscrewing them by hand. Carefully lower the P-trap and empty any water into the bucket.
