Alpha Hot Water Connecting Pipe Blending Valve 1.031351

The Alpha 1.031351 is a hot water connecting pipe assembly with an integral blending valve, used on Alpha Wall Hung Flowsmart 50 appliances. It carries domestic hot water through the appliance and blends the flow to regulate the delivered water temperature. The assembly is supplied as a single pipe and valve unit for direct fitment to the appliance.

• Domestic hot water temperature fluctuating between hot and cold at the tap
• Blending valve seized or failing to modulate, leaving water consistently too hot or too cold
• Scale or debris build-up inside the valve body restricting flow
• Water weeping or dripping from the pipe connections or valve body
• Reduced hot water flow rate through the appliance

• Confirm the appliance is an Alpha Wall Hung Flowsmart 50
• Check the part number on the existing pipe or valve assembly against 1.031351
• Inspect the pipe connections and valve body for scale, corrosion or damage before fitting
• Verify the fault is with the blending valve or connecting pipe rather than the thermistor or diverter
