Drain pipes work by gravity, and the slope is what carries the waste away. Too little slope leaves water standing, and too much leaves the solids behind.
The rule
Most home drain lines slope a quarter inch per foot, which is just enough to move water and solids together without leaving either behind.
The too-flat
A line that is too flat drains slowly and lets solids settle, which is how recurring clogs start.
The too-steep
A line that is too steep lets the water run away from the solids, which then build up and block the pipe.
The check
A level with a slope marking, or a camera inspection, confirms the grade. freezing winters put stress on exposed lines, and many older homes still have aging galvanized pipes In Sioux Falls, settling can throw off an old line's slope.
The quarter
The classic quarter-inch-per-foot slope moves water and solids together. Remembering that one number covers most home drains.
