How Old Is Kualapuu's Housing Stock?
With 90% of homes built before 1986, lead solder in plumbing is a potential concern. Federal law banned lead solder in drinking-water plumbing in 1986, but many older homes retain original plumbing.

Housing Age Profile
Some homes in Kualapuu predate the 1986 federal restrictions on lead in new pipe and solder, so a tap test is a reasonable step for older homes; median build year: 1967.
Over half of homes in Kualapuu were built before 1986, when federal law began restricting lead solder in drinking-water plumbing. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

Protecting Children from Lead in Kualapuu
Why children are most at risk: The CDC states that no safe blood lead level in children has been identified. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
If you have young children or are pregnant, consider testing your home's water - especially if your home was built before 1986.
