What it is
The Altecnic Calflow Plus is a 15mm flow regulator that limits the flow rate through the pipework to 15 litres per minute. It is supplied in the green variant and is used for flow regulation on boiler and heating systems, holding the set flow rate steady regardless of pressure fluctuation elsewhere in the circuit.
Signs this part needs replacing
- Flow rate at the outlets no longer matches the 15 litres per minute setting
- Flow becomes erratic, rising and falling as other outlets are opened or closed
- Reduced hot water output or uneven performance across a multi-outlet system
- Visible scale, debris or corrosion around the regulator body or connections
- Leaks or weeping from the body or its connections
Before you order
- Confirm the pipework is 15mm at the point of installation
- Confirm the required flow rate for the application is 15 litres per minute
- Check that the green variant matches the identification used on the existing part
- Check access and orientation at the installation point before removing the existing regulator
