A Washington buyer's inspector finds evidence of galvanized steel pipes in a 1955 home. The inspector should note that galvanized pipes:

AAre superior to copper pipes for longevity
BCan corrode internally over time, potentially affecting water quality and flow rate, and may be near end of useful life✓ Correct
CAre required to be replaced by Washington building code before sale
DOnly affect the water supply, not the drain lines

Explanation

Galvanized steel pipes were common in older homes but corrode from the inside out over time, reducing water pressure, affecting water quality (reddish discoloration), and eventually failing. Homes with original galvanized pipes from the 1950s are often approaching or past end of service life.
