On plumbing plans, piping that runs below the floor slab or underground is most commonly drawn using which line type?
a.A double solid line
b.A line with a row of circles
c.A heavy solid line
d.A dashed (broken) line
Giải thích
Concealed or below-grade piping is conventionally shown as a dashed line, while exposed or above-slab piping is a solid line. Distinguishing solid from dashed lines tells the installer whether a run is under the slab or overhead. Always confirm against the drawing's line-type legend.
