The bathroom basin is coming away from the wall & a tap needs replacing.
So, removed the basin and cut back the water feeds to allow me to fit the flex pipes.
After cleaning up the wall and removing the old trim, I fitted the basin back and attached the water supply, making sure the hot & cold were connected to the right tap, they were not before. Fixed the waste back and turned on the supply, checking there were no leaks.
Finished off with white silicone around the back of the basin to the wall. Job done.
