What it is
The return pipe filter is a component fitted to the return pipework of the Alpha CB50 (LPG) gas boiler. It captures system debris before the water re-enters the boiler, helping to protect the heat exchanger and internal waterways from sludge and magnetite build-up. It is supplied by Alpha under part number 1.012489.
Signs this part needs replacing
- Reduced heating or hot water performance as flow through the return path becomes restricted.
- Boiler overheating or repeated overheat lockouts during operation.
- Kettling, gurgling or rumbling noises from the heat exchanger.
- Visible sludge, magnetite or scale collected on the filter when it is removed for inspection.
- Frequent shutdowns or temperature fluctuations that persist after the system has been cleaned.
Before you order
- Confirm the appliance is an Alpha CB50 (LPG) before ordering.
- Check the part number 1.012489 against the manufacturer's parts list for your model.
- Isolate the boiler and drain down the system before removing the filter.
- Inspect the filter housing and surrounding pipework for damage while the filter is out.
