Hi everyone, I feel like a complete idiot. I went to replace my taps but there is a white attachment on the spindle (also not sure I am using the correct words!) that prevents me removing the flange and I don't know what it is and how to remove it... all advice welcome. Very new to this!!! ![20210511_050052[1].jpg 20210511_050052[1].jpg](https://us.v-cdn.net/6038643/uploads/migrated-attachments/1a80975496c3a2cb36ccef11e81887f6.jpg)
