Glow-worm 3-Way Diverter Valve GLOWWORM0020097214

The Glow-worm 0020097214 is a 3-way diverter valve used in the hydraulic circuit of Glow-worm domestic boilers. It routes heated primary water either to the central heating circuit or through the domestic hot water heat exchanger, allowing the boiler to serve one demand at a time. It is a hydraulic component and does not carry gas.

• No hot water at the tap while the heating continues to run normally
• Radiators warming up when only hot water is being drawn
• Domestic hot water temperature fluctuating, or running cold before recovering
• The diverter valve motor failing to move, or the valve sticking in one position
• Water weeping from the valve body or from its connections

• Check the boiler's model plate and GC number to confirm the part suits your appliance.
• Match the number 0020097214 against the marking on the existing valve.
• Inspect the joint seals and washers when the valve is removed and renew them if they are worn.
