What it is

The Glow-worm Hydroblock Flow, part number 0020064049, is a hydraulic component for Glow-worm Betacom combi boilers. It is listed as a diverter valve within the boiler's water circuit. It is supplied as a spare part for the Betacom 24C and Betacom 30C.

Signs this part needs replacing

  • Domestic hot water runs hot and cold intermittently.
  • Heating circuit warms up when hot water is drawn.
  • Boiler fails to switch cleanly between heating and hot water modes.
  • Water weeping or leaking from the hydroblock or diverter valve body.
  • Reduced hot water flow or unstable hot water temperature.

Before you order

  • Confirm your boiler model and GC number against the fitment list above.
  • Check the existing part number is 0020064049.
  • Inspect the hydroblock and surrounding hydraulic components for damage or leaks.
  • Confirm the fault is with the hydroblock rather than another component in the circuit.
