Drainage, Waste & VentQuestion 15 of 120
A cleanout is installed on a 2 in horizontal waste line in a finished room. What is the minimum clearance required in front of the cleanout?
a.6 in
b.8 in
c.18 in
d.12 in
Explanation
Cleanouts on 2 in and smaller pipe require at least 12 in of clearance in front of the opening for rodding, while pipe larger than 2 in requires 18 in. The 18 in figure is the wrong pipe-size row here, and 6 in and 8 in are below any code clearance.
