Annual and 5-year NFPA 25 inspection requirements for commercial buildings in Texas. Hydrostatic testing, dry pipe trip testing, backflow preventers, and fire marshal reports.
Commercial property managers and facility operators in Texas must maintain strict compliance with NFPA 25 fire suppression codes to avoid municipal citations and insurance cancellations.
Under Texas State Fire Marshal rules and NFPA 25, commercial systems require annual comprehensive testing, quarterly gauge/valve checks, and a rigorous 5-year internal pipe inspection.
Every five years, inspectors open pipe fittings at the system risers and cross-main ends to inspect for internal Microbiologically Influenced Corrosion (MIC), obstruction, and scale.
Backflow prevention assemblies must be tested annually by a licensed Backflow Prevention Assembly Tester (BPAT) certified by the Texas Commission on Environmental Quality (TCEQ).
