Toilet flush mechanisms need inlet and outlet valves working together to function properly. When the outlet valve starts wearing out, water slowly leaks from the cistern into the bowl. You'll hear that constant trickling sound, and it wastes hundreds of litres per day. A Buderim homeowner called us for same-day service, and our Sunshine Coast Plumbing and Hot Water technician found exactly this problem. The aging dual flush valve showed serious wear during inspection. Mineral buildup around the inlet valve was restricting water flow too. Both the outlet and inlet valves got replaced. We also installed a fresh flexible connection and upgraded the emergency shut-off device for added security. After thorough testing and commissioning, the system now runs silently with zero water waste.
