I am converting a bedroom in my house to a master bath, but the septic and drain field are on the opposite side of the house. I understand that I will have to cut the concrete floor to run my new pipes, but how much pitch should I give it ? Any info to make this project easy will help

I believe it's 1/4" per foot.

^^^ +1 to DM. Min is 1/4" per foot for what you are doing.

1/8" per foot if you use 4" pipe. In Canada, anyways. 1/4" per foot if you use 3" and smaller pipe.

Just be aware that where the slope of a drain is concerned, more is not better. Too much slope can allow the water to run ahead of the solid waste. The 1/4" per foot is said to be a good slope for drains.
