How long must a licensed master plumber maintain records identifying all welds?

A licensed master plumber is required to maintain records identifying all welds for a period of six years. This requirement is in place to ensure accountability and traceability in plumbing work, particularly regarding safety and compliance with building codes. Keeping detailed records allows for a thorough inspection and verification process, which is crucial for maintaining the integrity of plumbing systems.

Welding in plumbing is a critical process, as it directly impacts the durability and safety of installations. By retaining records for this duration, plumbers can provide evidence of compliance with relevant regulations and standards, ensuring that all work meets the required quality and safety benchmarks. This practice also facilitates maintenance or troubleshooting tasks, as a historical record of past work can be invaluable when assessing existing systems.

The specified timeframe of six years aligns with common regulatory practices, providing a balance between the need for oversight and the practicalities of record management within the plumbing industry.
