A dripping tap is one of those small household annoyances that can quickly become a major distraction. Beyond the repetitive sound, that steady drip can lead to a surprising amount of wasted water and an unnecessary increase in your monthly utility bills.
Most people assume a leak requires a massive repair job, but the solution is often found in a tiny, inexpensive component. Taking the time to address a leak early is a great way to maintain your home and keep your plumbing fixtures in top condition.
Learning how to change a tap washer is a valuable skill that empowers you to handle basic maintenance without any stress. This guide will walk you through the process of refreshing your taps with confidence and precision.
Gathering Your Tools and Supplies
Before you get started, it’s helpful to have everything you need within arm’s reach. A standard adjustable wrench, a pair of pliers, and a screwdriver are usually enough to get the job done. You’ll also need a packet of replacement washers from your local hardware store.
While you’re at the shop, consider picking up some plumbing grease or lubricant. Applying a small amount of this to the internal threads of the tap can make the handle turn much more smoothly. This little extra step adds a professional touch to your repair and helps extend the life of the tap components.
Safety First with the Water Supply
The most important step in any plumbing task is to turn off the water supply. You can usually find the isolation valve under the sink or near the basin. If there isn’t a specific valve for that tap, you will need to turn off the main water meter for your property. This is typically located near the front boundary of your home.
Once the water is off, open the tap fully to let any trapped water and pressure drain out. This prevents a sudden splash when you begin to disassemble the spindle.
Removing the Tap Handle and Cover
Most Australian taps have a decorative button on top that indicates hot or cold. You can usually pop this off with a flat-head screwdriver or a fingernail to reveal a screw underneath. Once that screw is removed, the handle should slide straight off. If it feels a bit stubborn, a gentle tug is usually all it takes to loosen it from the spindle.
After the handle is out of the way, you’ll likely see a metal shroud or cover. These are often decorative and can be unscrewed by hand. If the cover is tight, you can use your pliers, but wrap a cloth around the metal first to avoid leaving any marks on the shiny finish. Removing these parts gives you a clear view of the tap bonnet and the internal spindle.
Accessing and Replacing the Washer
Use your adjustable wrench to unscrew the tap bonnet. This is the large nut that holds the spindle in place. Once it’s loose, you can lift the entire spindle assembly out of the tap body. The washer is located at the very bottom of this assembly. It might be held in place by a small nut, or it may simply be sitting on a jumper valve that lifts right out.
Take the old washer out and replace it with a fresh one of the same size. If the old one looks flattened or has visible cracks, you know exactly why the tap was dripping. Make sure the new washer sits snugly in its housing so it can create a perfect seal against the tap seat.
Checking the Tap Seat
While the tap is apart, take a moment to look down into the tap body at the seat. This is the brass ring that the washer presses against to stop the water. If the seat is rough or has small grooves worn into it, a new washer might not solve the leak entirely. In many cases, a quick wipe with a clean cloth to remove any grit is enough to ensure a good connection.
If the seat looks particularly pitted, you might need a seating tool to smooth it out, but this is less common with modern fixtures. For most standard maintenance, a clean seat and a new washer are the perfect duo for a leak-free result.
Reassembling the Tap
Putting everything back together is simply a matter of reversing the steps you took earlier. Place the spindle back into the tap body and tighten the bonnet with your wrench. You want it to be firm, but there’s no need to use excessive force. Over-tightening can actually damage the new washer before it even gets to work.
Replace the decorative shroud and slide the handle back onto the spindle. Tighten the screw and pop the hot or cold button back into place. Before you turn the main water back on, make sure the tap is in the ‘off’ position. This allows you to monitor the tap closely as the pressure returns to the system.
Testing Your Handiwork
Slowly turn the water supply back on and head back to your tap. Open it slowly to let any air out of the line, then turn it off firmly. Watch the spout for a minute or two to ensure that the drip has vanished.
If the tap turns smoothly and stays dry, you have successfully completed the job. Regular maintenance like this prevents larger issues from developing and keeps your home running efficiently.
Final Word: When to Seek a Professional Touch
Most tap repairs are straightforward, but sometimes you might encounter a spindle that is completely seized or a leak that persists despite a new washer. If the tap is still dripping or if you find water leaking from the handle itself, the O-rings inside the spindle might need replacing as well. Whether it’s a single dripping tap or a full bathroom upgrade, having a professional look ensures that every connection is secure and every seal is perfect.
