Question

If, due to structural conditions, horizontal vents are less than 6 inches above the overflow rim of the fixture, the horizontal portion shall be installed with?

1) A slope of at least 1/4 inch per foot
2) A slope of at least 1/8 inch per foot
3) A slope of at least 1/2 inch per foot
4) A slope of at least 1 inch per foot

Answer 1

If horizontal vents are less than 6 inches above the overflow rim of the fixture due to structural conditions, the horizontal portion shall be installed with a slope of at least 1/4 inch per foot.The correct option is 1.

Step-by-step explanation:

If horizontal vents are less than 6 inches above the overflow rim of the fixture due to structural conditions, the horizontal portion shall be installed with a slope of at least 1/4 inch per foot. This slope is necessary to facilitate proper drainage and prevent the accumulation of wastewater in the vent. The slope ensures that water flows downward and away from the fixture, maintaining the functionality of the vent system.
