We promote getting the lead out of plumbing. It is also common to find lead in the plumbing system of a period home. The water service entrance, pipes, and lead solder joints can contribute to the lead level in drinking water. If the water stays in the pipes for too long, there is a good chance that it will eventually contain lead. We advise you run the tap water long enough for it to get very cold before drinking it. This will prevent ingesting the water that was in your pipes and which could contain lead.
