Structures built before the lead ban will be at a higher risk. The lead ban went into effect in Texas in 1988. Plumbing installed before 1988 can have lead in the solder, pipes, faucets, or fixtures, which can leach into the water supply over time.
Developments built in the past 35 years would have neither lead service lines nor private plumbing lines that are lead, but plumbing fixtures in the home or business could contain lead. From 1986 to 2014, plumbing fixtures could contain up to 8% lead to be categorized as, “Lead free.” However, current standards for “lead-free” fixtures allow no more than 0.25% of lead content.
