What it is

The Vaillant filling loop, part number 0020083527, is a boiler component used to top up system water pressure on Vaillant EcoTEC PLUS VU appliances. It sits within the isolation valve group on the boiler and allows the heating circuit to be pressurised from the mains supply. It is listed for the EcoTEC PLUS VU range.

Signs this part needs replacing

  • Boiler pressure drops repeatedly and the system needs frequent topping up
  • Water weeping or dripping from the filling loop valve or hose
  • The valve will not close fully, allowing system pressure to creep up
  • Stiff or seized valve handle that will not turn
  • Visible scale or corrosion around the valve body or connections

Before you order

  • Confirm your boiler model against the fit list above
  • Check the GC number on the appliance data badge matches the listed models
  • Inspect the existing filling loop to confirm the part is correct for your installation
