Alpha Pipe No.3 Domestic Hot Water Outlet 1.019923

Pipe No.3 is the domestic hot water outlet pipe supplied by Alpha for use in District Heating appliances. It forms part of the hot water circuit, carrying heated water away from the heat exchanger or store towards the domestic hot water draw-off point. The pipe is identified by Alpha part number 1.019923.

• Visible weeping or dripping from the pipe body or at its connections
• Corrosion, pitting or green/white scale deposits on the pipe surface
• Reduced domestic hot water flow at the outlets served by this pipe
• Kettling, gurgling or air ingress traced to the hot water outlet pipework
• Discolouration or deformation of the pipe indicating overheating or prolonged scale build-up

• Confirm your appliance is an Alpha District Heating Direct or District Heating LOW Pressure model
• Check the existing pipe against Alpha part number 1.019923 before ordering
• Inspect the surrounding connections and seals, as these may also need attention when the pipe is replaced
• Verify the fault is with the pipe itself rather than a blocked or scaled circuit elsewhere
