Soil Pipe

I am starting a remodel of the basement. The soil pipe is in a peculiar place. I was wondering about re-routing it. Is it possible to put a 90 degree on it. Or what is the maximum degree of bend I should use.

We want to help, but

sometimes, a question tells us the person doesn't have the knowledge or skill to venture into a particular project. I feel this is one of them.

Suggest you find a good plumber

I agree with Toolaholic. There are many factors to consider when revising a sewer line, and if you don't have knowledge of the basics, you would likely create a monster that would eventually have to be redone at considerable expense. You should get a plumber to do this project right. You might be able to cut expenses by doing some of the grunt work like digging and breaking concrete, but this is a time for a professional.
