We have a very slow draining bathroom sink, but it's finicky. I say this because in the evening everything seems fine with water running for 5 minutes. In the morning, water builds up in the sink and it takes about 1/2 hour to drain out. Last night, I used the Liquid Plumr Foam Snake formula as directed. Everything seemed fine as I ran water for a good 10 minutes with no issues. Now, this morning, we are back to A

Any suggestions?

I am about to call the plumber, but just want to make sure I am not missing anything here. I am not about to go tearing out pipes myself. :-)


EDIT: I am residing on the first floor of a 2-story condo complex of 8 units (4 units per floor) if that helps.
