Housing Age Profile
Because the majority of Canterbury's housing predates 1986, when lead solder was banned from new plumbing, the median build year of 1971 reflects a city where lead-era plumbing materials are common rather than exceptional.
Over half of homes in Canterbury were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.
