Step 1: Install the Faucet

Install the faucet onto the sink first. Start by fitting the faucet onto the sink and then attaching the water supply lines to the faucet. Hand tighten the supply lines, then finish tightening one-quarter to one-half turn with an adjustable wrench.

Step 2: Attach the Tailpiece and the Trap

Attach the tailpiece to the drain hole of the sink (Image 1). Attach the trap (often referred to as a P-trap or a J-trap) to the tailpiece (Image 2) by sliding the trap nut and washer onto the tailpiece and tightening them onto the trap. Attach the wall tube to the trap (Image 3).

Step 3: Attach the Supply Lines

Attach the supply lines to the water supply valves. Place a rag beneath the supply valves in case there are any leaks.

Step 4: Place the Sink

Place the sink against the wall, and connect the wall tube to the drainpipe extending from the wall. Turn on the water and check for leaks. Allow the water to run for a while so you can be sure there aren't any wet areas. You may want to secure the sink to the wall or floor to prevent it from shifting.
