A leak or dripping faucet can be a nuisance. It wastes water and increases costs, which are already high in Melbourne. Learning how to replace a tap washer is a straightforward DIY job.
In this guide, you’ll learn how to change a tap washer. These steps are easy, and you can complete this project quickly.
Tap washers are small components shaped like a disc. They are typically rubber, nylon, or fibre and create a watertight seal to stop water flow. It sits between the tap handle and valve seat. Its purpose is to prevent leaking when the tap is off.
Tap dripping is likely the result of a worn-out tap washer. Ignoring it leads to wasted water and higher water bills.
Replacing tap washers is a simple and effective solution that helps you maintain your taps and avoid bigger plumbing issues.
When dealing with persistent leaks or older fixtures, it can sometimes be a sign of underlying wear in your home’s plumbing system. Many homeowners turn to professional residential plumbing services in Australia to ensure the problem is fixed correctly and to prevent further damage that DIY repairs might overlook.

Before you start the process of changing tap washers, gather these items:
When selecting washers, look for high-quality ones with a long useful life.
Now, you’re ready to replace the tap washer and fix that annoying leak. This process is straightforward, but it does require a bit of care and attention to detail. Taking your time will help you avoid mistakes, protect the tap’s finish, and ensure all parts are put back together correctly. Follow these steps carefully, and you’ll have your tap working smoothly again in no time.
First, shut off the water supply. Usually, this is at the isolation valve or main stopcock. Locate it and turn it to the off position to prevent leaking or water damage.
Next, use a plug or a cloth in the sink drain so that any small parts like screws or washers don’t fall in. Keeping your work area tidy is another way to prevent this from happening.
The third step is to gently pry off the decorative cap or button with a flathead screwdriver. Be careful with the pressure you apply, and you won’t damage it.
Next, unscrew and remove the tap handle. These may be tightly screwed in and seem stuck because of water deposit build-up. You can try vinegar or penetrating oil if this is the case with your handle. The adjustable spanner can be helpful, too. Cover the handle with a cloth so you don’t damage its finish.
Step five is the removal of the skirt and bonnet. Cover the tap’s internal components. Use the adjustable scanner. Once off, put them to the side, organising all parts for quick reassembly.
Next, pull out the spindle after the skirt and bonnet. Be gentle and apply even pressure so you don’t strip the threads.
Take it out and look for signs of hardening or damage, which may be the culprit of the leaking. During this step, you can also inspect the washer seat for wear.
Compare the old washer to the new ones to verify you have the correct size. Then press it into place on the spindle and secure it. Dab some plumber’s grease onto the washer to improve sealing and the lifespan of the part.
Screw the bonnet and skirt back and reattach the handle. Ensure each part is tightened correctly. Over-tightening can cause damage and make it harder to remove for future jobs of changing tap washers.
Turn your water back on and see if the leak is gone. Slowly turn the water supply back on and test for leaks. If drips persist after the replacement, the causes may be a corroded tap seat, a worn valve stem, or a damaged O-ring.
