What it is

The Biasi BI1001505 is a domestic hot water (DHW) filter and pressure reducing valve for Biasi gas boilers. It filters the incoming mains water supply and reduces it to a stable pressure for the DHW circuit. The assembly is supplied with a filter kit.

Signs this part needs replacing

  • Reduced or fluctuating hot water flow at the taps
  • Water pressure from the DHW circuit too high, causing noise or discharge from the pressure relief valve
  • Debris or scale build-up in the filter, leading to restricted flow
  • Leaks from the valve body or connections
  • Unstable hot water temperature

Before you order

  • Check the boiler model and GC number against the Fits list above.
  • Confirm the part number on your existing valve is BI1001505 or the superseded code BG1001505.
  • Ensure the valve is for the domestic hot water circuit, not the heating circuit.
  • Check whether your boiler requires the filter kit to be replaced at the same time.
