I know the line wants to be as straight as possible, with few bends. I know it wants to have more than 45* of drop, and/or less than 1/2" per foot drop. My question is how many turns and bends is too many turns and bends so that the solids flow too slowly and the waste water out runs them......leaving the solids stopped in the line.....???? Is there a formula like no more than "X" amount of degrees of bends per ten foot of run...???
