Cleanouts in horizontal drainage lines must be spaced no more than:
a.100 feet apart
b.50 feet apart
c.75 feet apart
d.150 feet apart
Giải thích
The CPC requires cleanouts in horizontal drainage piping to be installed not more than 100 feet apart measured along the developed length. Spacing at 50 or 75 feet is stricter than required, and 150 feet exceeds the maximum, leaving a run that cannot be fully cleared with standard equipment.
