- simonblack 5y agoI probably wasn't clear-enough. After sufficient time has elapsed, the amount leached out drops further and further. After several years (a lot less than many plastic pipes' lifetimes) that amount of leaching will have dropped to very low levels. Just like radio-activity never actually drops to zero, but declines exponentially to negligible amounts after around 10-20 half-lives, I similarly see the same thing happening with plastic-leaching. As I said earlier, we don't appear to have had enough studies on the problem which look at things like plastic-leaching half-lives. As for not ageing well, I'm not either. <grin>
