Rice and Carrots and Lettuce, Oh My!

My mother called me at work today (she’s in town, staying with us). She was in the basement asking how to make my printer work.

She mentioned that it smelled musty down there, which it does, a little.

But when I got home, Stacey said there were puddles downstairs, presumably from the rain storm of late.

I went down to investigate, and noticed that one of the puddles was composed mostly of ground up rice, carrots and lettuce. Directly below the kitchen sink pipe.

So… does anyone have a plumber recommendation to fix rusted-through pipes?
