|In response to Re: Gravity Drain|
: I am installing a toilet in a basement and can easily get aboe the drain line but need to know the general rate of decline that is neccessary for proper flow.
the upc code states that any line 3" or less must be 1/4" per foot or 2%. a 4" line if needed can be 1/8" per ft. you only need a 3" line for 1 stool.Dale
