Governing Standards for Sodium Hypochlorite (NaOCl - Bleach) Service
What to Avoid in Sodium Hypochlorite (NaOCl - Bleach) Service
- Carbon steel valves
- Bronze or brass valves - copper contamination
- SS 316 for concentrated NaOCl
Service Considerations
- NSF/ANSI 61 certification required for valves in contact with potable water treatment chemicals
- No copper alloys - Cu ions from bronze/brass create toxic byproducts (CHCl₃)
- Temperature control critical - NaOCl decomposes rapidly above 25°C
- Ventilation mandatory in pump rooms - Cl₂ release if acid accidentally contacts NaOCl
