"Green plumbing" sounds vague, but in practice it's about concrete, measurable water and energy efficiency. The most effective measures reduce water use, lower energy bills, and often improve comfort too. Here are seven practical green plumbing tips for a more water-efficient Gold Coast home.
1. Fix leaks promptly
Every dripping tap and running toilet wastes water continuously. Fixing leaks is the most immediate water-efficiency action you can take, because it stops waste that runs around the clock. A single running toilet can waste hundreds of litres a day. See our guides on signs of a leaking toilet and signs of a water leak
2. Install water-efficient fixtures
Replacing old fixtures with high WELS-rated alternatives is one of the highest-impact green plumbing measures:
- Showerheads — a water-efficient showerhead reduces water use per shower by 30–50% and cuts hot water energy costs.
- Toilets — a dual-flush toilet with a 4-star WELS rating uses a fraction of the water of an older single-flush model.
- Taps — water-efficient tapware and aerators reduce flow without noticeably affecting usability.
3. Install a rainwater tank
A rainwater tank captures water from your roof for garden irrigation and, with the right plumbing, toilet flushing and laundry. On the Gold Coast, where summer storms deliver plenty of rain, a tank can significantly reduce mains water use. See our guide on the benefits of installing a rainwater tank
4. Upgrade to an efficient hot water system
Hot water is one of the largest energy uses in most homes. Upgrading to an efficient system — a heat pump, a correctly sized continuous flow system, or a solar system with a gas or electric booster — can reduce energy use significantly. The right choice depends on your household and energy source. See our hot water services and our guide on hot water system sizing
5. Insulate hot water pipes
Insulating the hot water pipes between the system and the fixtures reduces heat loss, so the water arrives hotter sooner and less energy is wasted heating water that cools in the pipes. It's a relatively inexpensive measure that improves efficiency and comfort — you wait less time for hot water to reach the tap.
6. Install a tempering valve
A tempering valve delivers hot water at a safe, controlled temperature, reducing the risk of scalding and preventing the system from overheating water unnecessarily. It also means you're not mixing excess cold water at the tap, which wastes both hot and cold water. See our guide on why you might not have enough hot water
7. Maintain your plumbing system
Preventative maintenance extends the life of your plumbing and fixtures, reducing waste from premature replacement. Regular hot water system flushing, drain inspections, and prompt repairs all keep the system efficient. See our guide on how to prolong the life of your plumbing system
Start with the biggest wins
If you want to prioritise, start with fixing leaks and upgrading showerheads and toilets — these deliver the biggest water savings for the least effort. Hot water system upgrades and rainwater tanks are larger investments that pay off over time. If you'd like help implementing any of these, contact our Gold Coast team for advice and installation.
