Default Toilet drain pipe slope.

i am putting a bathroom in my basement where there is NO piping at all, i have to chisel out the concrete floor and lay new pipes and everything. My biggest concern is what kind of slope do i need from where the toilet is to where the sewage exits my house. I want to make sure that its going to drain out and not backup or plug on me.

The standard in my area is 1/4" per 4' length.

There are systems now made to allow you to hook up whole bath where pipes don't exist and tie into the exising pipes. Called a macerator(?)

Welcome Npelzer:
Getting back to your original question; your drain line should have a minimum fall of 1/8" per foot (an 8' line would have 1" of fall from end to end) and a maximum of 1/4" per foot. The pump systems are great but if you have the space to get the proper fall, there is no need to go to the expense.
In a low fall situation all junctions should be made with wyes instead of tees; Y's get the waste flowing in the right direction before they enter the main line.
Glenn
