Planning & EstimatingQuestion 277 of 360
When planning cleanout locations on a long horizontal building drain, what is the maximum spacing between cleanouts under the CPC?
a.50 feet
b.100 feet
c.150 feet
d.200 feet
Explanation
CPC 707.4 requires cleanouts on horizontal drainage lines to be spaced not more than 100 feet apart, measured along the developed length of pipe. Additional cleanouts are also required at changes of direction. Locating them on the plan up front avoids code violations and eases future clearing.
