Hi all, I'm a new pool owner for a few months and this site has been wonderfully helpful. I'm in the process of upgrading a Kreepy Krauly (with a Poolvergnuegen 4X!). Upon dismantling the Krauly, I noticed this weight bar had several of its weights worn through the plastic enclosure. These feel like they are made out of lead (but I would hope not). Should I be concerned about having lead contamination in my pool now?
