Tools Required for Changing Kitchen Tap

To replace a kitchen tap, you will need a few essential basic tools. Here is a list of what you need and how they work;

Tools Required for Changing Kitchen Tap

  1. Adjustable Wrench: An adjustable wrench, also known as a crescent wrench, is a versatile tool that can be used to loosen and tighten nuts and bolts of different sizes. It has an adjustable jaw that can be opened or closed to fit different sizes of nuts and bolts.
  2. Basin Wrench: A basin wrench, also known as a sink wrench, is a long-handled tool designed specifically for tightening or loosening nuts that are located in tight spaces, such as behind a sink. It has a long handle with a swivelling jaw that can reach around obstructions and provide greater leverage.
  3. Screwdriver: A screwdriver is a handheld tool used for driving screws into wood or other materials. It comes in different types and sizes, including flathead and Phillips heads, and can be used to loosen or tighten screws that hold the tap in place.
  4. Plumber’s Putty: Plumber’s putty is a soft, pliable material that is used to seal gaps between the tap and sink. It helps prevent water from seeping through the gap and causing damage to the sink and surrounding areas.
  5. Pliers: Pliers are a versatile tool that can be used to grip and twist objects, such as supply hoses and mounting bolts. They can also be used to cut or strip wires.
  6. Bucket: A bucket is a useful tool to have on hand when replacing a kitchen tap. It can be used to catch any water that may spill out when disconnecting the supply hoses or removing the old tap.

Step-by-Step Guide to Change Kitchen Mixer Tap

  1. Inside a quarter-turn tap, there are two ceramic discs with precisely cut openings.
  2. When the handle is turned 90 degrees, the discs align, allowing water to flow.
  3. Turning the handle back closes the openings, stopping the water instantly.


Key Features:

✔ Fast & effortless operation – No need to twist multiple times.

✔ Drip-resistant – Ceramic discs reduce wear and tear.

✔ Smooth movement – Ideal for all ages, especially seniors or those with mobility issues.

How to remove the old kitchen mixer tap

Remove the old tap

To remove the old tap, follow these instructions:

1. Turn off the Water Supply

Before you start removing the old tap, turn off the water supply to the sink. The shut-off valves are usually located underneath the sink.

2. Disconnect the Supply Hoses

Once you’ve turned off the water supply, use pliers to loosen and disconnect the supply hoses that are attached to the bottom of the tap. Make sure to place a bucket underneath to catch any water that may spill out.

3. Remove the Mounting Nuts

Locate the mounting nuts that are holding the tap in place. These are usually located underneath the sink and can be removed using a basin wrench or adjustable wrench.

4. Remove the Tap

Once you’ve removed the mounting nuts, gently lift the old tap out of the sink. It may be helpful to wiggle it back and forth to loosen it.

5. Clean the Sink

After removing the old tap, use a cleaning agent and a soft cloth to clean any build-up or debris around the mounting holes. This will ensure a clean and smooth surface for installing the new tap.

By following these simple steps, you can successfully remove the old tap and prepare the sink for the installation of a new one.

Fit the new mixer tap

After removing the old tap, you can now fit the new kitchen mixer tap using these steps:

Installing new kitchen mixer tap

1. Insert the New Tap

Begin by inserting the new tap into the mounting holes in the sink. Make sure to align the tap correctly and secure it in place.

2. Attach the Mounting Nuts

Once the tap is in place, attach the mounting nuts underneath the sink using a basin wrench or adjustable wrench. Make sure the tap is securely fastened in place.

3. Connect the Supply Hoses

Reconnect the supply hoses to the bottom of the tap and tighten them using pliers. Make sure the hoses are not kinked and are connected securely.

4. Install the Aerator

The aerator is a small attachment that screws onto the end of the tap. It helps regulate water flow and prevent splashing. Screw the aerator onto the end of the new tap.

5. Turn on the Water Supply

Finally, turn on the water supply to the sink and test the new tap for leaks. If you notice any leaks, tighten the connections and retest until there are no more leaks.

By following these steps, you can successfully fit a new kitchen mixer tap and enjoy a fully functional and updated kitchen sink.

How Long Does it Take to Replace a Tap?

Replacing a kitchen tap can be a quick and easy process if you have the necessary tools and experience. However, the length of time it takes to replace a tap can vary depending on several factors.

Firstly, the complexity of the installation process can impact the time it takes to complete the job. If you are simply replacing a standard tap with a similar model, the installation may only take a few hours. However, if you are installing a more complex tap with additional features or need to make modifications to the sink or plumbing system, the installation may take longer.

Your level of experience with plumbing and DIY projects can also impact the time it takes to replace the tap. If you are a novice, it may take longer to complete the installation as you navigate the process and troubleshoot any issues that arise. On the other hand, if you are experienced with plumbing and DIY projects, you may be able to complete the installation more quickly and efficiently.

Overall, the length of time it takes to replace a tap can vary depending on several factors, but with the right tools and experience, you can complete the job in a timely manner and enjoy a fully functional and updated kitchen sink.

Outstanding plumbing service!
Chris was incredibly professional, punctual, and thorough. He quickly found the cause of our drainage issue using a camera inspection and explained everything clearly. The job was done neatly, efficiently, and with great attention to detail. Highly recommend Chris for anyone needing a reliable and skilled plumber.
Greg Whalan
Dial up plumbing were honest and upfront with the costs associated with the job.
In addition, they also too made a video of the problem areas with ongoing comments while the job was being performed.
I’d recommend these guys to anyone who have plumbing issues

My family are very satisfied and impressed with this plumbing company. We live in the Liverpool area. Charlie visited us for a quote on a kitchen tap replacement and toilet repairs. He was very friendly and professional, took the time to explain the repairs and discuss prices. Chris then carried out the repairs the same day and he was equally as friendly and professional. We were so impressed with the work.
We also had an emergency hot water system repair after hours the next week. We contacted Charlie who was so very helpful over the phone. Losing hot water can be stressful but he put us at ease. He attended within 30 mins and again explained the issue and cost. Once we agreed on the price he completed the repairs right away and we had hot water again. I have to say again how helpful Charlie was to us because losing hot water can be stressful especially the time of night everyone needs to shower. We are so grateful to finally find a plumbing company that is professional, honest, friendly and genuine on both occasions.
