How do I identify and fix the issue?

Plug the sink 

The last thing you want is to lose any vital pieces of your tap or components. They will literally be down the drain and finding new parts may not be easy.

Remove the tap button, handle, skirt and bonnet 

You do this using a screwdriver or spanner to expose the inside of the tap. This will also help to  determine the type of tap you have. The tap skirt is usually made from metal and may need a bit of extra wiggling and jiggling to remove it. Once you have the tap skirt off, you can use a pair of pliers to remove the sealant. When doing this, be careful not to scratch or damage your tap. Finally, for the tap bonnet (otherwise known as the tap body), you’ll need the help of a spanner.

Important Note: When disassembling your tap, don’t get the pieces mixed up! Line your parts up on a piece of paper and if you don’t have an elephant memory, it is best to label them. That way you can put your tap back together without wondering if you have done it backwards or upside down!  

Remove the washer and jumper valve

Now that the outer pieces have been removed, you’ll be able to locate the washer and jumper valve. Remove both using a pair of tweezers.

Replace the washer and jumper valve

Now it is time for a trip to your local Bunnings or hardware store! Take the washer and jumper valve and buy replacement parts. You may also need to buy some silicone skirt sealant if you had to remove it in the earlier step.

Reassemble the tap 

Install the new washer and jumper, ensuring that all the pieces you initially removed have been reassembled in the correct order and aligned properly. Use a spanner to tighten but don’t use the silicone yet, this will be the final step. 

Now to test your DIY skills!

Turn the water back on

The first step is to make sure your tap is turned off.  You would be surprised how many people forget to check this. Once you are sure your tap is off, you can turn on the water main.

Test the tap for leaks 

Turn the tap on and if it is no longer leaking, congrats you fixed it! Now you can remove the skirt and handle to add silicone to the skirt base as a sealant. 

My tap is still leaking 🙁

If your tap is still leaking, this is likely the sign of a much larger issue and you will need the help of a professional plumber.
