hi folks, i have been building my tub setup using, in part, 3/4" brass valves, flow meter, fittings, and so on. nearing the end of the build i was alarmed to find that a nipple i bought was labelled unsafe for drinking water. this may be a direct consequence of my living in california. in any case, this paper describes the surprisingly varying levels of lead in brass plumbing fittings. unfortunately, i already bought rather a lot of brass fittings without ever noticing that they had different levels of lead. this leads me to believe i should either presume the worst (8% Pb) or replace everything. i realize the tub water is not for ingestion, but there are children involved.
what levels of lead in fittings are considered safe for bathing? (not sure if this is the same for swimming and hot baths.)
