Alpha Fitting Collar Inlet Manifold to Diverter 1.015633

The Alpha 1.015633 is a fitting collar that connects the inlet manifold to the diverter valve inside Alpha's CB and CD range of boilers. It sits within the hydraulic assembly, where it holds the manifold-to-diverter joint secure and keeps the water path sealed under normal operating pressure. The collar is supplied as a single component and is listed by Alpha under the diverter valve and hydraulic components part type.

• Water weeping or a visible drip at the joint between the inlet manifold and the diverter valve
• Cracking, distortion or corrosion on the collar body
• Scale or debris packed around the collar seating, preventing it from pulling down evenly
• Falling system pressure with no leak found elsewhere on the appliance
• The diverter valve failing to seat correctly, with hot water performance dropping off as a result

• Check the GC number on the appliance data badge. This part is listed against GC numbers 47-532-14, 47-532-15, 47-532-16, 47-532-17, 47-532-19, 47-532-21, 47-532-25, 47-532-26, 47-532-27, 47-532-29, 47-532-30 and 47-532-44.
• Confirm your boiler model against the compatibility list below before ordering, as the same collar is used across a number of CB and CD variants.
• The collar also appears on older paperwork and parts labels as 1250136 or 015633, so check any previous invoice against those numbers.
