Altecnic 1/2 MxF Flow Limiter 10 Litres/min (Light Blue) 534110

This is a 1/2 in male x female flow limiter from Altecnic, rated at 10 litres per minute and colour-coded light blue within the Altecnic flow regulation range. It restricts the volume of water passing through a circuit to a fixed maximum, which stabilises flow rates across outlets and protects downstream components. It is a plumbing and heating system component rather than an appliance part.

• Measured flow at the outlet is consistently above the rated 10 litres per minute
• Flow rate becomes erratic or varies between draw-offs where it was previously steady
• Reduced flow through the fitting, indicating scale or debris build-up in the restrictor
• Visible weeping or drips at either connection
• Water hammer or noise from the pipework when taps or valves are operated

• Confirm the pipework connections are 1/2 in and that a male x female arrangement suits the installation
• Check the required flow rate against the 10 litres per minute rating for the circuit being balanced
• Verify the light blue colour coding matches the flow rate intended for that part of the system
• Check available space and access around the fitting before removal of the existing component
