A dripping tap might seem like a minor nuisance, but left unchecked, it can waste thousands of litres of water each year and slowly drive up your utility bills. If you’re wondering “why is my tap dripping?” or you’re tired of hearing that consistent drip…drip…drip in the middle of the night, you’re in the right place. At Plumbform, we’re big on helping homeowners understand what’s going on behind the scenes with their plumbing, and more importantly, what you can do to fix it.
Common Causes of a Dripping Tap
There’s more than one reason why your tap might be dripping, and it often depends on the type of tap you have. Whether it’s a standard compression tap or a modern mixer, the underlying issue usually comes down to worn components or build-up within the mechanism. Identifying the right cause is key to a proper fix, and it saves you time, water, and money.
How Worn Washers Lead to Leaks
One of the most common leaky tap causes is a worn-out washer. Every time you turn your tap on and off, the washer is pressed against the valve seat, which over time causes it to wear down. A misshapen or hardened washer won’t seal properly, leading to those slow and frustrating drips. The good news? Replacing a washer is usually a simple job, but it does require turning off your water supply and having the right tools on hand.
Issues With O-Rings and Seals
The O-ring is a small rubber component that helps seal various parts of your tap, especially around the handle. If you’ve noticed water leaking from the base of the handle rather than the spout, the O-ring could be the culprit. Like washers, O-rings can perish or loosen with age, making them another common reason why your tap is dripping.
Problems in Mixer Taps
Mixer taps work a little differently – instead of separate hot and cold controls, they combine both into a single cartridge. If the cartridge is faulty or clogged, it can cause inconsistent water flow or persistent dripping. Swapping out the cartridge can be a bit fiddly depending on the tap model, and it’s something we’re happy to help with if you’re unsure.
Build-Up of Mineral Deposits
Brisbane’s water is generally quite clean, but it’s not immune to mineral build-up – especially in older homes or properties with ageing pipework. Over time, minerals like calcium can accumulate on internal parts of your tap, making it harder for them to seal properly. This is one of those reasons why your tap is dripping that can creep up slowly and often goes unnoticed until the drip becomes more frequent.
Water Pressure and Drips
Too much of a good thing isn’t always great; especially when it comes to water pressure. High water pressure can strain your tap’s internal components, forcing water through even the smallest gaps. If your tap only drips at certain times (like at night), it might be a pressure-related issue. In this case, the problem isn’t the tap itself… it’s your overall plumbing setup.
When the Tap Body is Damaged
In some cases, the tap body may be cracked or corroded, especially in older fixtures or outdoor taps exposed to the elements. Even the smallest hairline crack can interfere with how the tap seals, leading to persistent leaking. If this is the case, replacement is usually more cost-effective than repair.
Signs It’s Time to Replace the Fittings
If you’re constantly dealing with drips, multiple worn-out parts, or recurring issues across several taps in your home, it might be time to consider replacing the fittings entirely. New taps aren’t just more efficient; they can also modernise the look of your kitchen, bathroom, or laundry. And in the long run, they can save you from ongoing maintenance headaches.
Can a Dripping Tap Increase Your Water Bill?
Absolutely – a single dripping tap can waste up to 20,000 litres of water per year. That’s not just bad for the environment; it’s also money down the drain. Even slow drips add up over time, which is why it’s worth addressing the issue early rather than letting it linger.
When to Call a Plumber
If you’ve replaced the washer, checked the O-ring, cleaned out any mineral build-up, and your tap is still dripping… it’s time to call in a licensed plumber. At Plumbform, we’ve seen it all. Whether it’s a hidden valve issue, an underlying pressure problem, or something that just won’t stop leaking, we’re ready to sort it quickly and properly.
