Alpha 1.015421 1/2 Inch Isolating Valve - Cold Water Inlet

The Alpha 1.015421 is a 1/2 inch cold water inlet isolating valve manufactured by Alpha for use on CD32C appliances. It sits on the cold water feed into the appliance and provides a means of shutting that supply off at the unit itself. Isolating the inlet in this way allows service, repair or component replacement to be carried out without draining down the wider system.

• The cold water supply cannot be shut off at the appliance when the valve is closed
• Water weeps or drips from the valve body, spindle or connection points
• The valve handle is stiff, seized or turns without changing the flow
• Scale or debris in the valve prevents it seating properly
• The appliance cannot be isolated for servicing without draining the supply

• Check the part number on the existing valve or in the appliance documentation against 1.015421
• Note the previous Alpha part code 1.021391, which may be marked on older stock
• Confirm whether a sealing washer or gasket is required at the connection before fitting
• Verify the connection size and appliance family, as the CD32C is the only family listed for this valve
