Likely Pipe Material

Housing Age Profile

While newer cities carry lower aggregate plumbing risk from lead-era construction, King Of Prussia sits firmly in the older category. The median build year of 1974 indicates that more than half the housing stock was built before 1986, when lead solder was still legally used in residential copper plumbing - and a substantial portion likely predates 1970, when lead pipes were still commonly installed for service lines. These two thresholds together define the elevated plumbing risk environment that older housing cities carry, independent of what the municipal water supply delivers to the meter.
