Whether you’re upgrading for style or fixing a leaky faucet, this guide has you covered.
Tools and Materials Needed
Having the right tools and materials on hand is essential for a smooth tap replacement process.
This section outlines everything you’ll need to get started, from the basics to extras that can make the job even easier.

Essential Tools for Replacing a Kitchen Tap
To get started, you’ll need some basic tools that are likely already in your toolbox. Here’s a list:
- Adjustable wrench
- Screwdrivers (Phillips and flathead)
- Pliers
- Basin wrench
- Bucket or towel (to catch water drips)
Optional Tools for Enhanced Efficiency
If you want to make the job even easier, consider these optional tools:
- Headlamp for better visibility under the sink
- Tape measure to confirm faucet dimensions
- Silicone sealant for a waterproof finish
Materials and Replacement Parts
You’ll also need the following materials:
- Your new tap or faucet
- Flexible water supply lines (if not included with the tap)
- Plumber’s tape (Teflon tape) to prevent leaks
Preparation Before Starting
Proper preparation can save you time and frustration. Before diving into the replacement process, there are a few important steps to take to set yourself up for success.

Turning Off the Water Supply
The first step in replacing a kitchen tap is to turn off the water supply. Locate the valves under the sink and twist them clockwise until tight.
If your sink doesn’t have shutoff valves, you’ll need to turn off the main water supply for your home.
Clearing the Area Under the Sink
Next, clear out the space beneath your sink. Remove any cleaning supplies, bins, or other items. Trust us – you don’t want to work in a cramped space with clutter in your way.
Ensuring Proper Lighting and Accessibility
It’s no fun fumbling in the dark. Use a flashlight or headlamp to illuminate the area. If possible, position a small stool or mat to make crouching more comfortable.
Understanding Kitchen Tap Types
Not all kitchen taps are created equal. Understanding the different types available can help you choose the best replacement for your needs and style.

Single-Handle Vs. Double-Handle Faucets
Single-handle taps offer simplicity and easy temperature control with one lever, while double-handle taps provide separate controls for hot and cold water.
Consider your preferences before purchasing a new tap.
Pull-Down and Pull-Out Taps
Pull-down and pull-out taps are great for added flexibility. They let you direct water exactly where you need it, whether washing dishes or filling large pots.
Wall-Mounted Vs. Deck-Mounted Faucets
Wall-mounted taps attach to the wall, freeing up countertop space. Deck-mounted taps are installed directly onto the sink or counter, a more common setup in most homes.
Australian Plumbing Standards to Keep in Mind
Ensure your new tap complies with Australian WaterMark certification standards. This guarantees that the tap meets safety and water efficiency requirements.
Step-by-Step Guide to Replacing a Kitchen Sink Tap
Replacing a kitchen sink tap involves several stages. Here’s a detailed, step-by-step guide to help you through the process.

Removing the Old Tap
Before installing your new tap, you’ll need to remove the old one. This involves disconnecting the water supply and detaching the old tap from the sink.
Disconnecting Water Supply Lines
Using your adjustable wrench, loosen and disconnect the water supply lines from the tap. Place a bucket underneath to catch any remaining water.
Loosening and Removing Mounting Nuts
With a basin wrench, unscrew the mounting nuts holding the tap in place. Be patient – these can be stubborn, especially if they’ve been there a while.
Extracting the Old Tap
Once the nuts are off, lift the old tap straight up. You might need to wiggle it a bit if it’s stuck due to mineral buildup.
Preparing the Sink for the New Tap
Before installing your new tap, it’s important to prepare the sink area to ensure a secure and leak-free fit.

Cleaning the Mounting Area
Use a damp cloth to clean any debris or residue around the mounting holes. This ensures a snug fit for your new tap.
Inspecting for Damage or Wear
Check the sink’s surface and fittings for cracks or wear. Addressing these now can save you headaches later.
Installing the New Tap
With the old tap removed and the sink prepared, it’s time to install your new tap. Follow these steps for a successful installation.
Positioning and Securing the New Tap
Insert the new tap into the mounting holes. Align it properly before tightening the mounting nuts beneath the sink.
Connecting Water Supply Lines
Reattach the water supply lines to the new tap, applying plumber’s tape to the threads to prevent leaks.
Testing the Installation
Turn the water supply back on and test the tap. Check for leaks and tighten connections if necessary.
Common Issues and Troubleshooting
Encountering problems during or after installation is common. This section addresses frequent issues and how to resolve them effectively.

Dealing With Leaks After Installation
Leaks are often caused by loose connections or missing plumber’s tape. Double-check these areas to resolve the issue.
Addressing Loose Connections
If the tap wobbles, tighten the mounting nuts under the sink. You may need to hold the tap steady from above as you do this.
Fixing Low Water Pressure
Low pressure could indicate a clogged aerator. Unscrew the aerator, clean it with vinegar, and reattach it.
