What happens here

Begin by connecting the P-trap to the existing wall drain connection. Ensure a new rubber washer is used inside the slip nut for a secure seal. Attach the straight pipe from the P-trap to the T-fitting. Connect the double-ended tailpiece to the other sink's basket strainer, ensuring a rubber washer is in place and removing any plastic burrs from manufacturing for a smooth seal. Measure and cut the necessary length for the horizontal pipe connecting the two sink tailpieces to the T-fitting. Use a Rigid ratcheting cutter for clean cuts. Ensure all pipes are aligned and hand-tightened first. Apply a small amount of pipe thread sealant (e.g., Mega Lock) to the threaded connections for an extra layer of protection against leaks. Ensure proper slope for drainage. Before final tightening, check for any mold pieces or burrs on the inside edges of the PVC pipes, as these can cause leaks. Use a utility knife or reamer to smooth these edges.

Goal: This step details the assembly of the new PVC drain pipes, including the P-trap, double-ended tailpiece, and connecting T-fitting, using rubber washers for leak-proof compression joints.
