Plumbing advice

[glatt]

Are you mocking me?

Your first post made it sound like you went to the store to buy a snake to fix your problem, but you saw that the one you wanted was too expensive. So you bought a smaller one instead, even though you think it's too small for the big jobs like this. That's why you are going to hire the plumber.

Nowhere in your post do you say that you tried the smaller one.

I've used snakes like the one you are talking about, and they are pretty good. I'm trying to save you the money of hiring a plumber. 25 feet is very long. It should be able to reach the clog and break it up. You probably don't need a plumber.

Of course, if you have already tried it and failed, that's another story.
