Is an air test acceptable for a storm and sanitary system?

An air test is considered acceptable for a storm and sanitary system primarily when a water test is not feasible or practical. This is particularly relevant in cases where water is not readily available, or in circumstances where flooding could occur or where water could cause damage to other ongoing work or installations. The air test serves as a viable alternative to demonstrate the integrity of the piping systems by ensuring there are no leaks present, which can lead to water infiltration or other issues.

When conducting an air test, it is important to adhere to specific guidelines and requirements set forth in plumbing codes or standards. While a water test is typically preferred for its ability to visualize leaks, in situations where it cannot be performed, the air test becomes a useful tool for system verification.

Other options present limitations or conditions that may not align with accepted plumbing practices or code regulations regarding the integrity testing for storm and sanitary systems. Understanding the context and permissible testing methods enhances the ability to ensure proper system functionality while adhering to safety and regulatory standards.
