Foam water solution shall be tested every:

Foam water solution shall be tested every:

• A. Daily
• B. Weekly
• C. Monthly
• D. Year

Answer: (D)

Foam-water solution testing is performed annually because the mixture and the equipment that create it are designed for long-term stability. The test verifies that the foam concentrate remains compatible with the system, that the correct foam-to-water proportion is still being delivered, and that the proportioning devices, pumps, and lines are functioning properly. Since the solution sits in the system and isn’t used constantly, frequent testing (daily or weekly) isn’t necessary and would be impractical. Monthly checks would be excessive for this type of system, while an annual test aligns with standard maintenance practices to ensure reliable performance without unnecessary disruption.
