Upstairs bathroom sink not draining at all (24 hours to drain half a sink worth of water). I've snaked it, used liquid plumber pro for hours, twice. Cut into the wall, pipe seems to have sufficient fall, all other drains in the house drain fine. What do I do??

Hi Kenzie

Did you remove the pop-up plug itself? If not, remove the pop-up plug (loosen nut under sink) and see what kind of mess is attached to the pop-up plug... could be the issue right there... ;).

Start there and let me know what you find, OK?
