What is a Duo Valve & Why is It Important?

A Duo Valve is a crucial component in electric hot water systems that prevents backflow and regulates water pressure entering the system. It protects your hot water unit and plumbing by ensuring water only flows in the correct direction.

Signs You Need a Duo Valve Replacement:

✔ Hot Water System Leaking – A failing valve may allow water to escape.
✔ Reduced Water Pressure – A blocked or worn-out Duo Valve can restrict water flow.
✔ Water Backflow Issues – Dirty or discolored water can indicate backflow contamination.
✔ Unusual Noises in Pipes – Water hammering or whistling sounds suggest valve failure.
✔ Old or Worn-Out Valve – Duo Valves should be replaced every 5-10 years for efficiency and safety.
