At what differential pressure should Helen strainers be cleaned?

Helen strainers should be cleaned at a differential pressure of 3 PSID to ensure optimal performance and maintenance of the system. This pressure differential indicates that the strainer is becoming clogged or is experiencing a buildup of debris. Cleaning at this threshold helps prevent excessive strain on the system, reduced flow rates, or potential equipment failure.

Cleaning at this point is a balance between efficiency and protection of the system. Lower thresholds, like 2 PSID, might lead to unnecessary cleaning cycles, while waiting until higher thresholds could result in performance issues or damage. Therefore, 3 PSID is a practical and effective point for maintenance, allowing for a balance between performance and upkeep of the strainers.
