How to Install a Bathroom Sink Tailpiece

Installing a bathroom sink tailpiece is a fundamental aspect of setting up a functional sink system. It is accountable for establishing a leak-proof connection between the P-trap and the drain hole of the sink.

The tailpiece is made of materials like chrome-plated brass, stainless steel, or plastic. The selection of materials influences its durability and corrosion resistance.

The dimensions of the tailpiece, including its length and thread size, vary based on the type of sink and drain assembly. It is essential to determine the appropriate dimensions to ensure a perfect fit.

In addition to the tailpiece itself, you will need a slip-joint washer, a lock nut, and a P-trap kit. The slip-joint washer creates a seal between the tailpiece and the P-trap, while the lock nut holds the tailpiece in place. The P-trap kit consists of a P-shaped trap and a drainpipe, which together prevent sewer gases from escaping into the bathroom.

Installing the tailpiece involves several steps. First, you need to disconnect the old tailpiece and remove the slip-joint washer and the lock nut. Next, clean the drain hole and apply a thin layer of plumber's putty around the base of the tailpiece.

Insert the tailpiece into the drain hole and tighten it with the lock nut. Ensure that the slip-joint washer is properly seated between the tailpiece and the P-trap. Finally, connect the P-trap kit to the tailpiece and secure it with the wing nuts.

By following these steps precisely, you can successfully install a bathroom sink tailpiece, ensuring a leak-proof and functional drain system for your bathroom.
