That annoying drip from your kitchen or bathroom tap might seem like a minor issue. But a leaking tap is more than just an irritation — it’s costing you money and could be a sign of bigger problems.

How Much Water Does a Dripping Tap Waste?

The numbers are surprising:

• One drip per second = over 12,000 litres per year
• A steady trickle = up to 40,000 litres per year
• A fast leak = over 100,000 litres per year

At Melbourne’s current water rates, even a slow drip adds a noticeable amount to your water bill every year. A faster leak costs significantly more.

Common Causes of Leaking Taps

Worn Tap Washers

The most common cause. Rubber washers wear out over time and lose their seal. This is usually a quick, affordable fix.

Damaged O-Rings

The O-ring is a small disc that helps keep the tap handle in place. When it wears out, you’ll notice leaking around the base of the tap.

Corroded Valve Seat

The valve seat connects the tap to the spout. Mineral deposits can cause corrosion, leading to leaks.

Worn Cartridge

Modern mixer taps use cartridges instead of washers. These can wear out and need replacement.

High Water Pressure

Excessively high water pressure can cause taps to drip, especially at night when demand is low and pressure is highest.

The Hidden Costs of Ignoring a Leak

A leaking tap doesn’t just waste water:

• Water damage - Persistent moisture around sinks causes wood rot, mould, and damage to cabinetry
• Mould growth - Damp areas breed mould, which poses health risks
• Staining - Constant dripping leaves mineral stains on sinks and basins
• Worsening damage - Leaks never fix themselves — they only get worse
• Higher bills - Wasted water adds up month after month

Can You Fix a Leaking Tap Yourself?

For a simple washer replacement, DIY is possible if you’re handy. However, be aware:

• You need to turn off the water supply first
• Different tap types require different approaches
• Over-tightening can crack the tap body
• Incorrect repairs can make the problem worse
• In Victoria, certain plumbing work must be done by a licensed plumber

When to Call a Professional

Call a plumber if:

• The leak persists after replacing the washer
• You have a mixer tap or ceramic disc tap
• There’s leaking from the base or body of the tap
• You notice water damage around the tap area
• Multiple taps are leaking (could indicate a pressure problem)
• You’re not confident doing the repair yourself
