At my previous apartment, I had a city employee test my water. They let faucet run for about 10 minutes, then took a sample and got basically immediate results and told me the pipes were leaded. If that’s all it takes to test positive, then the protection can’t be that effective. The tech was in my apartment for less than 15 minutes, and 10 minutes of that was just letting the faucet run.
They tell us that there is no safe amount of lead, and they can detect the presence instantly. That tells me there’s not much protection. Even if it takes 10 minutes to get past that protective layer, after taking a shower your water wouldn’t be safe anymore until there’s another buildup.

The ten minutes is to get a lower reading not a higher one. The longer the same water sits in those pipes the more shit it absorbs from the pipes.
