For how many years must records of backflow prevention inspections be retained?

The retention period for records of backflow prevention inspections is mandated to ensure that there is a documented history of compliance with safety regulations and to facilitate future inspections. Retaining these records for five years allows for a comprehensive review of the backflow prevention systems in place, enabling authorities to track maintenance, any required repairs, and the overall effectiveness of these systems in preventing contamination of the public water supply. This timeframe also aligns with various state and local regulations, which typically require a minimum retention period to uphold public health standards. Keeping these records readily accessible supports efficient management and accountability within plumbing practices.
