What it is

The Alpha 6.5638310 is a pipe that connects the three-port diverter valve to the domestic hot water cylinder on the Alpha 500 E boiler. It carries heated water between the valve and the cylinder coil as part of the hot water circuit. The component is supplied by Alpha as a spare for the 500 E appliance.

Signs this part needs replacing

  • Water weeping or dripping from the pipe joints or unions
  • Visible corrosion, pitting or scaling on the pipe surface
  • Reduced or no hot water from the cylinder while the boiler still fires
  • The three-port valve failing to divert, with debris or blockage present in the pipework
  • Kinked or distorted pipework restricting flow

Before you order

  • Confirm the appliance is an Alpha 500 E
  • Check the existing pipe routing and the connections at both the three-port valve and the cylinder
  • Match the part number 6.5638310 against the number on the existing component
