7 Simple Ways to Save Water and Reduce Your Plumbing Bills
By Joel - Licensed Plumber, Hobsons Bay Plumbing
Water prices in Melbourne continue to rise, but small plumbing upgrades and habit changes can make a real difference. Here are seven practical ways to reduce your water usage and lower your bills - most of which pay for themselves within a year.
1. Fix Dripping Taps Immediately
A single dripping tap wastes up to 20,000 litres per year. That's around $50–$80 on your water bill for just one tap. If you have multiple dripping taps in your home, the cost adds up fast. Most tap repairs take under 30 minutes and cost far less than the water you're losing.
2. Install WELS-Rated Tapware
Replacing old taps with 4-star WELS-rated taps can reduce water flow by up to 50% without noticeable pressure loss. Look for the WELS label when buying new tapware - a 4-star tap uses around 4.5 litres per minute compared to 15+ litres for older models.
3. Upgrade to a Dual-Flush Toilet
Older single-flush toilets use 11–12 litres per flush. A modern dual-flush toilet uses just 3 litres (half flush) or 4.5 litres (full flush). For a family of four, that's a saving of over 35,000 litres per year.
4. Check Your Toilet for Silent Leaks
A running toilet can waste up to 60,000 litres per year - and you might not even notice it. To test: add a few drops of food colouring to the cistern. If colour appears in the bowl within 15 minutes (without flushing), you have a leak. Usually it's just a worn flapper valve - a quick, inexpensive repair.
5. Install Low-Flow Showerheads
A standard showerhead uses 15–20 litres per minute. A 3-star WELS-rated showerhead uses just 6–7 litres per minute. For a household that showers 20 minutes per day total, that's a saving of over 90,000 litres per year.
6. Insulate Your Hot Water Pipes
Uninsulated hot water pipes lose heat as water travels from the tank to your tap. This means you run the tap longer waiting for hot water - wasting both water and energy. Pipe insulation (lagging) is inexpensive and reduces heat loss by up to 80%.
7. Get a Plumbing Health Check
Many homes have hidden leaks - under slabs, behind walls, or in underground pipes. A plumbing health check can identify issues before they become expensive problems. Signs of hidden leaks include:
- Unexplained increases in your water bill
- Damp patches on walls or floors
- Water meter spinning when all taps are off
- Mould or musty smells in specific areas
