How to Change Bathroom Sink Mixer Tap: A Comprehensive Guide

Replacing a bathroom sink mixer tap may seem like a daunting task, but with the right tools and a bit of preparation, you can easily complete it yourself. This step-by-step guide will provide you with everything you need to know to change your bathroom sink mixer tap successfully.

Tools and Materials

Before you begin, gather the necessary tools and materials:

New bathroom sink mixer tap
Adjustable wrench
Plumber's putty
Joint sealant tape (Teflon tape)
Bucket or basin
Old rags

Step-by-Step Instructions

Step 1: Turn Off the Water Supply

Locate the water shutoff valves under the sink or behind the access panel in the bathroom closet. Turn both the hot and cold valves clockwise to stop the water flow.

Step 2: Disconnect the Old Tap

Place the bucket under the sink to catch any water that drains out. Use the adjustable wrench to loosen the nuts that secure the hot and cold water supply lines to the old tap. Then, remove the nuts and disconnect the supply lines.

Next, loosen the lock nut that connects the old tap to the sink. Use care not to overtighten or damage the lock nut.

Step 3: Remove the Old Tap

Once the supply lines and lock nut are loosened, lift the old tap straight up and out of the sink opening.

Step 4: Clean and Seal

Use old rags to clean the sink surface and remove any old putty or debris. Apply a thin layer of plumber's putty around the base of the new tap's mounting flange.

Step 5: Install the New Tap

Insert the new tap into the sink opening and align it properly. Tighten the lock nut by hand as much as possible.

Step 6: Reconnect the Supply Lines

Apply joint sealant tape to the threads of the new tap's inlet connections. Then, hand-tighten the supply lines to the appropriate inlets.

Step 7: Tighten and Seal

Use the adjustable wrench to further tighten the lock nut. Be sure not to overtighten. Finally, wrap another layer of joint sealant tape around the base of the tap where it meets the sink and tighten it with the wrench.

Step 8: Turn on the Water Supply and Check for Leaks

Turn on the water shutoff valves and allow water to run through the new tap. Check for any leaks at the connections. If you notice any leaks, tighten the connections further or apply additional joint sealant tape.

Tips

If you are replacing an old-style tap with a mixer tap, you may need to purchase an adapter.
Use a plastic or rubber cap to protect the wrench from scratching the tap.
If you are not comfortable working with plumbing, do not hesitate to call a licensed plumber.
