What it is

The Ferroli 39840720 is a filling loop cock/valve used on Ferroli Modena HE and Domicondens HE combi boilers. It forms part of the filling loop assembly that allows the sealed heating circuit to be topped up and pressurised from the mains cold water supply. The valve controls the flow of water into the system during filling and isolates the connection once the correct pressure is reached.

Signs this part needs replacing

  • The boiler loses pressure repeatedly and requires frequent topping up
  • Water weeps or drips from the filling loop valve body or its connections
  • The valve spindle is stiff, seized or will not shut off fully
  • System pressure continues to rise after the filling loop has been closed
  • Visible scale, corrosion or damage around the valve seating

Before you order

  • Confirm the boiler model and product code against the fit list above
  • Check the existing valve for the part number 39840720 where visible
  • Inspect the filling loop connections and washers for damage before refitting
  • Isolate the mains water supply and depressurise the system before removal
