I have a leak under my sink, the leak in question is coming from the part i've crudely circled, I cannot see anything similar from googling "sink plumbing" what is part called in case i have to replace it and what is it actually for? and does anyone know how i'd go about stopping it leaking?
The leak only really occurs if i fill the sink and release the plug, it doesnt tend to happen if i have the tap running with the plug out.
Would appreciate any advice. [/img]
