A dripping tap might seem like a minor annoyance, but over time, it can lead to bigger problems—both for your home and your wallet. Whether it’s the kitchen, bathroom, or laundry, that slow, steady drip can be a sign of something that needs fixing fast.

In this article, we’ll explain why taps drip, the potential consequences of ignoring them, how to fix a dripping tap, and when it’s time to call in a professional plumber.

Why is My Tap Dripping?

There are several reasons a dripping tap might occur:

• Worn-out washer or O-ring – The most common cause. Over time, washers inside the tap wear down and can no longer form a tight seal.

• Damaged valve seat – This is the connection between the tap and the spout. If it becomes corroded or worn, it can cause leaking.

• High water pressure – Excessively high pressure can cause water to leak out of your tap even when it’s turned off.

• Loose parts or fittings – General wear and tear or poor installation can lead to small leaks.

How Much Water Does a Dripping Tap Waste?

You might be surprised to learn that a dripping tap can waste up to 20,000 litres of water a year—enough to fill a small swimming pool! That’s not only bad for the environment, but it can also add a significant amount to your water bill over time.

Can I Fix a Dripping Tap Myself?

If you’re comfortable with a bit of DIY, you might be able to fix a dripping tap yourself. Here’s a basic step-by-step:

1. Turn off the water supply – Locate your isolation valve and turn it off to prevent flooding.

2. Plug the sink – Just in case you drop a small part.

3. Remove the tap handle – This usually involves unscrewing a cap or cover to access the internal components.

4. Replace the washer or cartridge – Depending on your tap type (compression, ceramic disc, ball, or cartridge), you’ll need the correct part.

5. Reassemble the tap and turn the water back on to test for leaks.

If the drip continues—or if you’re unsure what you’re doing—it’s best to get help from a licensed plumber.

Why You Shouldn’t Ignore a Dripping Tap

While a dripping tap may seem harmless, it can lead to:

• Increased water bills

• Water damage to benchtops, cabinetry, or walls

• Mould and mildew growth

• Corrosion or further damage inside the tap system

Fixing a tap early is often quicker and cheaper than dealing with the consequences later.
