Your path: I live in an older buildingLead from plumbing is the main question
Older buildings may have lead service lines, solder or fixtures. Lead is not in Youngsville’s published record, so only a tap test tells you. Test first-draw water, then filter if needed.
Your path: My water tastes of chlorineThe disinfectant is not in this record
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
