Long Drain Pipe for Toilet

I have a very large shed in the back yard ( about 18 X 30 Ft ) it is built on a slab and is really just used for storage and has pool equipment in it.

I would like to Close off one section and put in a bathroom that would be used in the summer. To do this would require running a 4 inch drain line for about 8 ft then make a 90 degree turn, go through the basement wall of the house, make another 90 degree turn and continue for about 20 ft to the main stack. I have plenty of space to provide a 1/4 inch or more of slope. Will this work, or is this too far to run a horizontal pipe?

Thanks,
Ron

drain

It is not too far as long as everything else is installed correctly, and in most cases you would only need a 3" pipe for the sewer.

When making the 90 degree horizontal turns, dont use regular 90s. Use either long sweep 90s or better yet, two 45s with a short piece of pipe inbetween them.

Great Advice

Thanks for the advice, I will definitely use the two 45's
