What it is

The Vaillant 0020010295 is a cold water inlet valve fitted to a wide range of Vaillant ecoTEC Plus combi boilers. It regulates the flow of cold water into the boiler, ensuring the correct amount of water reaches the system for safe, efficient operation, and allows manual isolation of the supply for maintenance, filling or pressure protection.

Signs this part needs replacing

  • Boiler loses pressure or will not hold pressure after re-filling
  • Valve will not fully isolate or shut off the cold water inlet
  • Visible leaking or dripping from the valve body
  • Difficulty filling or topping up the system pressure

Before you order

  • Match the part number 0020010295 against your existing valve before ordering
  • Isolate the mains water and gas supply before removal or fitting
  • Fitting must be carried out by a Gas Safe registered engineer
