How To Replace Bathroom Faucet 3 Hole

Replacing a 3-hole bathroom faucet is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, even a novice DIYer can tackle this task with confidence.

Gather Your Tools and Materials:

New 3-hole bathroom faucet
Adjustable wrench
Basin wrench
Pliers
Teflon tape
Plumber's putty
Bucket or bowl

Step 1: Turn Off Water Supply

Locate the water supply valves beneath the sink and turn them clockwise to shut off the water flow to the faucet.

Step 2: Disconnect Old Faucet

Use an adjustable wrench to loosen the nuts that hold the water supply lines to the old faucet. Then, use a basin wrench to loosen the nuts that hold the faucet to the sink. Once loose, remove the old faucet from the sink.

Step 3: Apply Plumber's Putty

Roll a ring of plumber's putty around the base of each new faucet mount and press it firmly into place. This putty will help create a watertight seal between the faucet and the sink.

Step 4: Position New Faucet

Place the new faucet over the sink holes and align it with the water supply lines and drain hole. Tighten the mounting nuts hand-tight using pliers.

Step 5: Connect Water Supply Lines

Wrap a layer of Teflon tape around the threads of the new water supply lines. Attach the lines to the faucet mount and tighten them with an adjustable wrench.

Step 6: Connect Drain Pipe

Slip the drain pipe over the drain assembly and tighten the slip nut. Ensure a snug fit without overtightening.

Step 7: Turn On Water Supply

Slowly turn on the water supply valves beneath the sink to allow water to flow through the new faucet. Check for any leaks around the faucet base and water lines.

Step 8: Adjust and Secure

Adjust the handles of the new faucet to ensure they operate smoothly and regulate water flow properly. If necessary, use an adjustable wrench to tighten the nuts that secure the faucet to the sink.
