Wet system testing should be conducted on what frequency?

Wet system testing is crucial for ensuring that fire protection systems, specifically sprinklers, function correctly in the event of a fire. Conducting these tests monthly is a widely accepted practice in the fire protection industry. Monthly testing allows for the regular monitoring of system performance, identification of any faults, and prompt corrective measures to be taken to ensure the system remains operational and reliable.

This frequency balances the need for thorough oversight without overwhelming maintenance obligations. Systems, when tested regularly, can help uncover issues like leaks, corrosion, or other physical changes that could impair performance. While other frequencies such as weekly, quarterly, or annually might be considered in varying contexts or for different types of systems, monthly testing provides a consistent and practical approach that aligns well with regulatory recommendations and industry standards for wet sprinkler systems.
