First time so forgive me if I am answering a stupid question.
6 months ago, fitted a new mixer tap to my sink "Moretti Flare Mono Sink Mixer" from screwfix. All went well, but now the tape is becoming extremely stiff when moving the spout between the 2 sinks.
The actual tap handle moves left and right fine to control temperature and up and down for flow. I wondered if there was any way to loosen or adjust the spout to make it move freely. When I purchased the tap, I noticed that it was supplied with an allen key and a small allen bolt at the base of the tap, but no instructions on what it was for. If this to adjust the taps spout from travelling from left to right?
