They're way too clogged, you must have too much horizontal plumbing in your house or you do the :boink: to yourself in there too much. Get one of those snakes, you might have to hire a plumber, cause it may be clogged further down.

Edit: One time I actually makeshifted a pump that forced pressure into the pipes, I used this plastic cup piece that molded around the drain, and attach my bike pump to it and held the cup in while someone pumped it. It won't do much if your pipes aren't fully clogged, cause there won't be any pressure if nothing is stopping it.
