When testing the soil, waste, and vent system, what is the minimum head of water required?

The minimum head of water required when testing the soil, waste, and vent system is set at 10 feet. This standard ensures that the system can withstand and be effectively tested for leaks under adequate pressure, which simulates the conditions that the system will encounter during normal operation.

Testing at this height allows for the detection of any potential weaknesses or failures in the joints and fixtures of the system that could lead to leaks or plumbing issues down the line. A head of water lower than this may not provide enough pressure to identify all possible failures, while a higher head could introduce unnecessary risk of damage or strain on the system. Therefore, adhering to the 10-foot minimum ensures a thorough and safe testing process.
