Question

Weekly fire sprinkler system inspections would include:




flow testing the system


ensuring cold weather enclosures are heated and sealed


draining the low points of the system


testing fire hoses

Answer 1

Typically only the cold‑weather check would be part of a routine weekly sprinkler inspection. Weekly inspections are mainly visual/operational checks (valve positions, gauges, signs of leaks or freeze risk, alarms/supervisory condition) — so verifying cold‑weather enclosures are heated and sealed fits.

The others are periodic tests that are not normally done weekly:
- Flow testing the system (full flow/inspector’s test) is a scheduled test at longer intervals.
- Draining low points (or main drain tests) is done as required/seasonally or at scheduled intervals, not routine weekly draining.
- Fire hose testing/pressure testing is handled under hose inspection/testing schedules (NFPA 1962) and is not a weekly sprinkler inspection item.

Always follow NFPA 25 and your AHJ/owner maintenance schedule for the exact frequencies.
