We’ve all been there – you’re washing up after dinner when you notice a few drips from the kitchen tap. Your first thought? “I’ll just pop down to the hardware store and grab a new washer.” And fair enough, too. Replacing a worn washer is often the quick, budget-friendly fix that gets your tap back in working order.
But here’s the thing: not every leaky tap can be saved with a simple washer replacement. Sometimes, your kitchen mixer tap is trying to tell you something more serious – that it’s reached the end of its useful life and needs to be replaced entirely.
After more than two decades helping Perth families with their plumbing needs, we’ve seen countless kitchen taps that have soldiered on well past their use – by date. While we absolutely admire the Aussie spirit of making things last, there comes a point where holding onto an old tap actually costs you more in water bills, potential damage, and sheer frustration than investing in a quality replacement.
So how do you know when it’s time to say goodbye to your old kitchen mixer tap? Let’s walk through the five key signs that indicate you’re better off replacing the whole unit rather than just changing the washer.
Sign 1: Water Is Leaking from the Base of the Tap
This is probably the most common and concerning sign we see. You’ll notice water pooling around the base of your tap, right where it meets the sink or benchtop. Give it a wipe, and within hours (or even minutes), that puddle is back again.
A kitchen tap leaking from the base is usually a sign that the internal seals or O – rings have deteriorated. Unlike a simple washer that sits at the end of the spout, these seals are deeper within the tap body and much more difficult to access and replace. In many cases, especially with older or budget mixer taps, the parts simply aren’t available separately.
But here’s why this particular problem is more serious than just annoying: that water sitting at the base of your tap can seep into your benchtop or cabinetry. If you’ve got laminate benchtops (as many Australian kitchens do), prolonged moisture exposure can cause swelling, warping, and delamination. Even stone benchtops aren’t immune – water can damage the sealant and potentially lead to staining or deterioration of the material underneath.
We’ve seen kitchen renovations required because a leaking tap base was ignored for too long. What could have been a straightforward tap replacement turns into replacing entire sections of cabinetry. Not ideal for anyone’s budget.
Sign 2: The Tap Body Has Visible Corrosion or Mineral Buildup You Can’t Remove
Perth’s water can be quite hard in many suburbs, and over time, mineral deposits build up on and inside your tapware. A bit of white crusty buildup around the aerator? That’s normal and can usually be cleaned with vinegar or a descaling solution.
But when you start seeing significant corrosion, pitting, or mineral deposits that won’t budge no matter how much elbow grease you apply, your tap is telling you it’s had a good innings. Corrosion that’s visible on the outside often indicates even worse deterioration happening inside the tap body where you can’t see it.
Chrome – plated taps, in particular, can develop issues where the plating wears through, exposing the base metal underneath. Once this happens, the corrosion process accelerates, and the tap becomes increasingly difficult to clean and maintain. Not only does this look unsightly, but corroded internal components can affect water flow and even water quality.
We’ve had customers who’ve persisted with heavily corroded taps, only to find that the constant cleaning required becomes a never – ending chore. At a certain point, the time and products you’re spending on maintenance make replacement the more sensible option.
Sign 3: You’re Constantly Adjusting the Handle to Get the Right Temperature
Remember when your mixer tap actually mixed water at the temperature you wanted? You’d set it just right, and it stayed there? If those days feel like a distant memory, and you now find yourself constantly fiddling with the handle to maintain a decent temperature, your tap’s internal cartridge is likely worn out.
Modern mixer taps use a cartridge system that blends hot and cold water. These cartridges are precision – engineered components, but they don’t last forever. Over time, the internal discs or ball mechanisms wear down, making it harder to achieve consistent temperature control.
In some quality tap brands, you can replace just the cartridge. However, for many mid – range and budget mixer taps, finding the correct replacement cartridge can be challenging. Even when you can source the part, the labour involved in replacing it – combined with the cost of the cartridge itself – often approaches the price of a new tap anyway.
There’s also a safety consideration here, particularly if you’ve got young children or elderly family members in the house. A tap that suddenly delivers scalding water because the temperature control has failed can cause serious burns. If your tap’s temperature control has become unreliable, that’s a sign it needs replacing sooner rather than later.
Sign 4: Reduced Water Pressure That’s Isolated to That One Tap
We all complain about water pressure from time to time, but if every other tap in your home runs fine and your kitchen mixer tap has slowed to a disappointing dribble, the problem is specific to that tap.
Start with the simple fixes first – unscrew the aerator (the little screen at the end of the spout) and check whether it’s clogged with sediment or mineral deposits. Give it a clean and see if that helps. If cleaning the aerator makes no difference, the blockage is somewhere inside the tap body itself.
Internal blockages can occur when sediment, mineral deposits, or even bits of corroded pipe work their way into the tap’s internal mechanisms. Sometimes these blockages can be cleared, but often they indicate that the tap’s internals have deteriorated to the point where debris is constantly breaking free and causing problems.
Reduced water pressure doesn’t just make washing dishes frustrating – it can also significantly increase the time your tap is running, which adds up on your water bill. If you’ve been struggling with poor flow from your kitchen tap for months, you might be surprised how much water you’re wasting.
Sign 5: Your Tap Is More Than 10 – 15 Years Old and Showing Multiple Issues
Here’s some perspective on tap lifespans: a quality kitchen mixer tap, well – maintained in average conditions, typically lasts between 10 and 15 years. Some higher – end models with excellent warranties might push beyond that, but it’s the exception rather than the rule.
If your tap is approaching or has passed this age and you’re experiencing multiple issues – perhaps a minor leak plus temperature control problems plus occasional reduced flow – it’s time to accept that your tap has done its job and deserves retirement.
At this age, even if you manage to fix the current problem, another issue is likely just around the corner. You’ll find yourself in a frustrating cycle of repairs, each buying you only a few more months before the next problem crops up.
There’s also the question of efficiency and technology improvements. Modern mixer taps often include features like water – saving aerators, smoother operation, and better temperature control. The water savings alone from a modern WELS – rated tap can make a noticeable difference to your bills over time.
What About the Cost to Replace a Kitchen Mixer Tap?
We understand that budget is always a consideration. The cost to replace a kitchen mixer tap varies depending on the style and quality you choose, but you can find excellent options at a range of price points.
At Budget Plumbing Centre, we work with Perth families to find solutions that meet both their functional needs and their budget. A basic but reliable kitchen mixer tap replacement might cost a couple of hundred dollars, while premium models with advanced features can run higher. Installation costs vary depending on whether it’s a straightforward swap or requires additional plumbing work.
Here’s something to consider: while replacing a tap is more expensive upfront than changing a washer, a failing tap can cost you in other ways. Wasted water from leaks, potential damage to cabinetry, and the frustration of dealing with ongoing problems all have a cost – some financial, some in terms of your time and peace of mind.
Making the Right Choice for Your Kitchen
If you’ve recognised your own kitchen tap in any of these five signs, it’s probably time to start looking at replacement options. But here’s the good news: choosing a new kitchen mixer tap is actually an opportunity to upgrade your kitchen’s functionality and style.
Think about how you use your kitchen. Do you often fill large pots? A high – spout tap might be perfect. Constantly washing vegetables? Look for a pull – out spray option. Want to reduce water usage? Check the WELS star rating to find water – efficient models.
When you’re selecting a new tap, quality matters. While it might be tempting to go for the cheapest option, a mid – range tap from a reputable brand will likely serve you better in the long run. Look for taps with good warranties – they’re a sign that the manufacturer stands behind their product.
Getting Professional Advice and Installation
While some handy homeowners might tackle a tap replacement themselves, there are good reasons to consider professional installation. A plumber can identify any underlying issues (like corroded pipes or incorrect water pressure), ensure the tap is properly sealed to prevent future leaks, and make sure everything complies with Australian plumbing standards.
At Budget Plumbing Centre, we’ve been helping Perth families since 2000 with everything from simple tap washers to complete kitchen renovations. Our experienced team can guide you through selecting the right kitchen mixer tap for your needs and budget, and we can arrange installation if required.

There’s really no substitute for trying out the handle action and seeing how the tap looks and functions before making your decision. Our friendly staff are always happy to share their expertise without any pressure – we’re here to help you find the right solution, not just make a sale.
Don’t Wait Until It’s an Emergency
One final piece of advice: don’t wait until your tap fails completely or causes damage before addressing the problem. We’ve seen too many situations where a tap that’s been “meaning to replace” suddenly breaks on a Friday evening or during the Christmas holidays, turning a planned upgrade into an emergency situation with limited options.
If you’ve noticed any of these five signs, start planning your replacement now while you have time to research options, compare prices, and make an informed decision.
