What it is
The CONNECTION RETURN SINGLE is a Buderus component for the boiler's return water circuit, where the returning heating water is connected back into the appliance. It is listed under Buderus part number 78168 and is classed within the manufacturer's gas boiler spares range.
Signs this part needs replacing
- Visible water weeping or a damp patch around the boiler return connection
- Corrosion, scale build-up or pitting on the connection body or its sealing face
- A joint that will not seal after re-making, indicating a distorted or damaged connection
- Discolouration or heat marking at the connection where the joint has been running hot
- Staining or drip marks below the appliance consistent with a slow leak on the return side
Before you order
- Confirm the appliance model and GC number match the boiler being worked on
- Check the part number 78168 against the existing component before removal where possible
- Inspect the surrounding pipework and seals, as a leaking connection can damage adjacent joints
- Isolate the appliance and drain down as required before fitting
