What it is
The Alpha by-pass cartridge (part number 3.025159) is a complete by-pass assembly for Alpha ECO 2 and InTEC 2 boilers. It sits in the boiler's by-pass circuit and regulates the flow of water around the primary circuit, which helps the appliance maintain correct flow rates and temperature differentials across the heat exchanger. It is supplied as a complete cartridge.
Signs this part needs replacing
- The boiler short-cycles or struggles to hold a steady flow temperature
- Overheating or flow-related fault codes appear
- Unusual noise from the boiler during operation
- Water weeping from the by-pass housing or cartridge
- Poor or inconsistent heating performance
Before you order
- Check your boiler model and GC number against the fitment list above
- Confirm the part number 3.025159 matches the cartridge currently fitted
- Establish whether your appliance requires the complete cartridge or a separate component
- Isolate and drain the boiler before removing the existing cartridge
