How to Replace a Basin Tap – A step by step guide

If you’re looking to upgrade your bathroom or simply need to replace a worn-out basin tap, you’ve come to the right place.

In this comprehensive guide, we will walk you through the process of replacing a basin tap, from start to finish.

Whether you’re a seasoned DIY enthusiast or a beginner looking to tackle a home improvement project, our step-by-step instructions will help you get the job done efficiently and with confidence.

Fitting a new basin tap – things to keep in mind

• Before replacing the basin tap, it’s a good idea to familiarise yourself with the fittings underneath the sink.
• Beneath the sink is large, plastic pipe – this is the waste that’s connected to the plug hole. The two smaller copper pipes are the hot and cold water pipes.
• The tap is screwed into the basin, and there will be screws and nuts that lock it in position.
• There may also be washers between the nut and the basin, which help protect the ceramic sink and ensure an effective seal.
• It’s a good idea to check if you need a compression fitting. This connects the water pipe to the flexible tap tail. There may be one fitted to the old pipes, but it’s possible the new pipes could be a different size, so therefore you may need a new compression fitting.
• Follow the steps below, and you’ll have your new basin tap fitted in no time.

Gather those tools and materials

Before you begin, make sure you have the following tools and materials on hand:

• Adjustable wrench
• Screwdriver

• Replacement basin tap
• Teflon tape
• Towels or rags
• Bucket or container
• Plumber’s putty (if needed)

Removing the Old Basin Tap

Step 1 – Remove the tap handle

• Use a screwdriver to remove the screw that holds the tap handle in place.
• Gently pry off the handle to reveal the valve beneath.

Step 2 – Loosen the locknut

• Using a basin wrench, loosen the locknut that secures the tap to the basin.
• Turn the wrench anti-clockwise to loosen the nut.

Step 3 – Disconnect the water supply lines

• Use an adjustable wrench to disconnect the water supply lines from the tap.
• Place a bucket or container under the connections to catch any remaining water.

Step 4 – Remove the old tap

• With the locknut and water supply lines detached, lift the old tap out of the basin.
• Clean the area around the tap hole and remove any old plumber’s putty or debris.

Installing the new basin tap

Step 5 – Apply plumber’s putty

• If your new tap requires it, apply plumber’s putty to the base of the tap.
• Insert the tap into the hole in the basin.

Step 6 – Secure with locknut

• Place the locknut onto the threaded tail of the tap.
• Hand-tighten the locknut, and then use a basin wrench to securely tighten it.

Step 7 – Connect water supply lines

• Reconnect the water supply lines to the new tap.
• Use an adjustable wrench to ensure a snug fit, being careful not to overtighten.

Step 8 – Attach the tap handle

• Slide the tap handle onto the valve stem.
• Secure it in place with the screw you removed earlier.

Testing and final steps

Turn on the water supply

• Slowly turn on the water supply valves.
• Check for any leaks around the new tap.
