The Hamworthy 530801019 is a water connection casting for the flow and return pipework on Hamworthy Modumax floor standing gas boilers. The casting carries threaded connections and forms part of the boiler's hydraulic pipework assembly. It is supplied as a service part under part number 530801019.

• Visible weeping or a drip from the casting or its threaded joints
• Rust staining or corrosion pitting on the casting body
• Water tracking down the flow or return pipework beneath the connection
• Threads that will not seal or have been cross-threaded during previous work

• Confirm the boiler model against the fit list above, as the casting is listed for Modumax floor standing units only
• Check the part number on the existing casting or the boiler's parts documentation matches 530801019
• Inspect the pipework and seals around the flow and return before ordering, as the leak source may be a joint rather than the casting itself
• Confirm whether the flow and return connections on the appliance are threaded as described before fitting
