Foam concentrate strainers inspection schedule?

Foam concentrate strainers inspection schedule?

• A. Daily
• B. Weekly
• C. Semi-annually
• D. Quarterly

Answer: (D)

Regular maintenance of foam concentrate strainers is essential to keep foam proportioning accurate and prevent debris from entering the foam mix. Debris and particulates in the concentrate can clog the screen, restrict flow, and throw off the proportioning, which compromises system effectiveness during a discharge. Strainers tend to accumulate contaminants gradually and aren’t subjected to constant cycling, so checking them on a quarterly basis provides a practical balance between catching buildup and keeping maintenance workload reasonable. During the inspection, look for signs of debris buildup, screen damage, corrosion, or any condition that would restrict flow. Clean or replace the screen as needed and ensure it is properly seated after maintenance. This schedule helps keep the system ready and reliable without unnecessary downtime, while longer intervals could allow blockages to develop.
