Thank you for the reply. Pressure is fine in other faucets (it's an apartment building). I am actually more concerned about inability to mix warm water in a reliable fashion.
The faucet is Franke FF-200. I called them and they suggested to start with the flow restricting part on the flexible extension pipe - he suspected it could've been either set to a too restrictive a value or clogged. Still not sure if it solves the mixing problem.
