Text in the illustration

rusting of galvanized pipe can greatly reduce water pressure and will eventually cause leaks as rust creates holes in the pipe walls
problems are likely to occur soonest on pipes carrying hot water, horizontal pipes and at threaded (thinner) sections

Generated explanation

The illustration shows a circular cross section and a longitudinal cutaway of galvanized steel water-supply pipe. Orange-brown rust deposits line the interior and narrow the water passage. Both views show water spraying through holes in the pipe wall caused by corrosion. The longitudinal view also shows a threaded pipe end. The annotations identify reduced water pressure and eventual leakage as consequences of rusting, with problems likely to occur first in hot-water pipes, horizontal runs, and thinner threaded sections.
