Timely repairs can significantly extend the life of your Dux system. Our plumbers replace worn components like sacrificial anodes and safety valves, preventing major breakdowns and maintaining energy efficiency.
We also support property owners with ongoing servicing and performance checks. If your system is more than five years old, a maintenance visit could save you from a costly emergency repair down the track.
