How many feet of head are required for testing a sanitary drainage system?

In Massachusetts, the plumbing code requires a minimum of 10 feet of head for testing a sanitary drainage system. This specific requirement ensures that the system can be adequately checked for any leaks, proper flow, and to confirm that there are no blockages present. The 10 feet of head creates sufficient pressure within the system to simulate real-world conditions that would occur during normal operation.

This testing standard is critical for confirming the integrity of the drainage system and ensuring that it complies with safety and performance standards. Utilizing less pressure than the required 10 feet could potentially overlook flaws or issues in the system that could lead to more severe operational problems or even health hazards in a functioning plumbing system.

Attention to specified testing requirements is vital for all plumbing professionals to ensure systems are safe, effective, and up to code.
