How often should strainers be inspected under normal flow conditions?

Strainers play a crucial role in fire protection systems by filtering out debris and preventing foreign materials from entering the water supply of sprinklers, which could impair their operation. Inspecting strainers annually under normal flow conditions ensures that they are functioning properly and are free from clogging or buildup that could hinder water flow in the event of a fire.

Annual inspections allow for timely detection of any issues, leading to proactive maintenance actions that can prevent failures during an emergency. Regular check-ups help maintain the efficiency of the entire sprinkler system and enhance its reliability when needed most.

Longer intervals, such as every two years or five years, may not sufficiently address potential issues that could arise due to sedimentation or other forms of contamination in the water supply, thus compromising the effectiveness of the sprinkler system. Quarterly inspections might not be necessary for most systems, as annually strikes a balance between thoroughness and practicality, ensuring that strainers remain in optimal condition without incurring excessive inspection costs.
