Hi Community,
I've encountered a strange issue with my basin tap. Water seeps around the tap quite quickly, even though I've shut off the hot and cold water supply valves below. I'm trying to determine whether I should replace the basin tap or inspect for further leaks.
My confusion arises because, despite turning off both the hot and cold water supplies (with no water coming from the tap itself), there is still seepage around it.
Any advice on why this might be happening and what steps I should take would be greatly appreciated.
Thank you!
