Advice
Practical tips for residents
Flush After Absence
If your home has been unoccupied for several days, run the kitchen tap for 30 seconds before drinking. This clears stale water that has been sitting in pipes.
Use Cold Water for Cooking
Always draw cold water for cooking and drinking. Hot water systems can leach metals from pipes and fittings, and cold water has less dissolved material overall.
Maintain Your Filter
If you use a water filter jug or benchtop system, replace the cartridge according to the manufacturer's schedule. An old filter can harbour bacteria and reduce performance.
