How to Change a Kitchen Tap (DIY – Do It Yourself)

Not all plumbing jobs require a professional plumber, a lot of domestic plumbing jobs can be DIY you can do yourself.

But there are certain plumbing tasks that you will need a professional plumber, and for that, we recommend that you call our plumber for them tasks.

Replacing your kitchen tap falls into the category of DIY jobs – Do it Yourself.

The Tools You Need to Replace Your Tap

To complete the job you’ll need certain tools, if you don’t have any of these tools you should make a trip to your nearby DIY store.

The tools you need are:

  • Your favorite tap
  • Monoblock tap spanner (usually a set of 3)
  • Box immersion spanner or a basin wrench (click here for a list)
  • Ajustable pliers (also known as water pump pliers)
  • Pipeslice 15mm pipe cutter (15mm is standard – check your pipework)

Step 1. Turn off your water supply

Locate the isolating valve also known as stopcock, you might find it under your sink, or outside your home.

Once you have found it, turn the valve only a quarter to turn off the water. You can test to see if it has worked by turning a tap on to see if any water comes out, that way you know if you have turned it off properly.

If you are 100% sure that there is no circulating water in your taps, you may proceed to the next step. If you still have running water, you may need to turn the valve a little more and test again.

Step 2. Disconnect your old tap

If your tap has the flexible type connections this is going to be very easy for you. You can use your adjustable pliers to do this job, unfasten the nuts where they join the mains pipe connections. A bit of common sense will also help complete this task.

Its now time to remove your old tap by using the tools needed, you can start by loosening the nut that keeps the tap attached to the surface, for this you will need the Monoblock tap spanner or depending on the space you might be able to use your adjustable pliers. Once you’ve removed your old tap, take the time to clean any nasty residue and any water buildup from the open mains pipe connections under the sink.

Step 3. Fit your new tap

It’s now time to install your new tap, fitting your new tap is far easier than removing one. Your new tap may have come with pre-fitted hoses, this will make this part of the task so much easier as you wont need to use the old hoses from your old tap.

It might be a good idea to grab the manufactures manual and follow the instructions. You may need to get someone to help you out by holding the tap in place while you fit the connections under the sink.

It’s now time to reconnect the mains supply, start the threads by hand to avoid cross-threading. Once you are happy that everything is tight, its now time to turn on your water supply.

Step 4. Turn your water supply back on

You can now turn on your water supply but only once you’re happy everything is connected and tight. All you have to do is adjust the isolating valve to its original position and your water supply should now be on. Give it a test and if everything is fine – congratulations! You’ve just replaced your tap successfully!
