Replacing a Tap: A Step-by-Step Guide


A leaking tap can be one of the most annoying and expensive problems to have around the house.

Not only does it waste water, but it can also cause costly water damage if left unchecked.

Fortunately, replacing a tap is a fairly simple process that anyone can do with the right tools and know-how.

Read on for a step-by-step guide on how to replace a tap in no time.

Turn off the Water Supply & Unscrew the Old Tap

Before you begin, make sure to turn off the water supply to your taps; otherwise, you could end up with a huge mess!

After this is done, unscrew the old tap by using an adjustable spanner or wrench.

You will need to remove both hot and cold taps as they are usually connected.

Once they’re both removed, undo any pipes that connect to them too.

Install New Washers & Screws

The next step is to install new washers and screws into your new taps before you start fitting them.

Make sure that each tap is thoroughly cleaned before adding any new parts, as this will help ensure that everything fits snugly in place when installed.

It's also important to check that all seals are properly fitted so that your taps don't leak once installed.

Fit The Taps

Make sure that all of the pieces are lined up correctly before attempting to fit them together with your hands or an adjustable spanner/wrench.

If you're having trouble getting them in place, use some WD-40 or another lubricant to help get them moving smoothly and easily into position.

Once they are in place, tighten them up until there is no more room for movement - just be careful not to over-tighten them as this could cause damage or breakage!

1. How do I turn off the water supply to my taps before replacing them?

To turn off the water supply to your taps before replacing them, you will need to locate the main shut-off valve for your home.

This is usually located near the water meter or where the main water line enters your house.

Once you have located this valve, turn it clockwise until it’s fully closed.

This should stop the water supply to all of your taps, making it safe for you to replace them.

2. What tools do I need to replace a tap?

To replace a tap, you will need a few basic tools. These include an adjustable wrench, pliers, screwdrivers and possibly a basin wrench.

You may also need some pipe sealant, a plumber’s tape, and a new tap washer.

It’s also a good idea to have some rags handy in case of any leaks.

Finally, it is always recommended that you wear safety glasses, gloves and other protective clothing when working on any plumbing job.

3. Is it necessary to use lubricant when fitting the new taps?

It is not always necessary to use lubricant when fitting new taps.

However, it is a good idea to use a lubricant such as a plumber’s grease or Vaseline if you are struggling to get the new taps into place.

4. Do I need any additional parts or pipe joint compound for the installation?

Depending on the type of tap you are replacing, you may need to purchase additional parts or pipe joint compound for the installation.

5. What should I do if the basin has cracks or is damaged?

If the basin has cracks or is damaged, you should replace it before installing your new taps.

You will need to ensure that the basin is properly sealed when installing it, as any leaks will cause damage to your taps.

6. How do I check my water pressure before installation?

Before installing your new taps, it is important to check the water pressure in your home.

You can do this by attaching a pressure gauge to the main water supply and turning on a tap.

If the pressure is too low, you may need to install a water pressure regulator before you can proceed with the tap installation.

If the pressure is too high, you may need to replace a regulating valve before you can install the new taps.

7. What should I do if I'm having trouble fitting the new taps in place?

If you are having trouble fitting the new taps into place, it is best to call a professional plumber.

A plumber will be able to assess the situation and provide you with the best advice on how to proceed with replacing your taps.

They will also be able to carry out the installation for you, ensuring that your taps are fitted correctly and safely.

8. Are there any additional considerations to keep in mind when replacing a tap?

When replacing a tap, it is important to remember to turn off the water supply before you begin.

You should also make sure that you have all the necessary tools and parts before starting the job.

Finally, it is always recommended to contact a professional plumber if you encounter any difficulties.

This will ensure that your taps are installed correctly and safely and that you do not cause any damage.

9. How can I contact a professional for help with replacing my tap?

If you need help with replacing your tap, there are several ways to contact a professional.

You can search online for local plumbers in your area ask friends and family for recommendations.

You can also contact a plumbing supplies store for advice and hire a professional if necessary.

By following these steps and consulting a professional, you can ensure that your taps are replaced correctly,

10. Is it necessary to go underneath the sink when replacing a tap in the bathroom or kitchen?

In most cases, replacing a tap in the bathroom or kitchen does not require going beneath the sink.

However, if you are replacing a tap in the bathroom, it is necessary to turn off the water supply before unscrewing the old taps.

If you are replacing a tap in the kitchen, you may need to go beneath the sink to access the pipes and fittings.


Replacing a tap can seem like an intimidating task at first but with the right tools and know-how, it’s quite easy!

All you need is an adjustable spanner or wrench, some new washers and screws, and maybe some WD-40 or another lubricant if needed.

With these few things at hand, you should be able to replace even the most stubborn of taps in no time at all!

So go ahead and give it a shot - you might surprise yourself with how much easier than expected it turns out to be!
