Because the majority of Ravensdale's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1987 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Ravensdale were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.
