Baxi DHW Flow Fitting 15mm 720543501

The Baxi DHW flow fitting is a 15mm connection component used in the domestic hot water circuit of Baxi and Broag Remeha Avanta Plus combi boilers. It forms part of the hot water side of the appliance, carrying water through the DHW assembly so the boiler can deliver a steady flow at the taps. A correctly seated, undamaged fitting is needed to keep that circuit leak-free and free of restriction. It is supplied under part number 720543501 and replaces previous number S62766.

• Weeping or visible water at the DHW flow connection, with dampness or staining around the joint
• Reduced hot water flow rate at the taps compared with normal operation
• Scale, sludge or debris restricting flow through the fitting
• Corrosion or water marking on the fitting body or on components immediately around it
• Unstable or intermittent hot water delivery traced back to the DHW assembly

• Check the model and GC number on the appliance data badge against the compatibility list before ordering.
• Confirm the number on the existing component where it is still legible; this fitting replaces previous number S62766.
• Inspect the mating joint and renew any gasket, O-ring or washer that is disturbed during the swap.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
