Where should the discharge from relief valves be piped to?

The discharge from relief valves should ideally be piped into an open receptacle. This practice is important for several reasons. Open receptacles allow for safe and effective venting of any excess pressure or fluid without the risk of backflow or blockage that can occur if the discharge is directed into closed systems. By using an open receptacle, the discharge can be observed and managed more easily, providing a visual indication of potential issues.

Additionally, directing the discharge into an open receptacle reduces the risk of creating hazardous conditions, such as water damage or pressure buildup within the plumbing system. It can also prevent the potential buildup of harmful gases or vapors that could be harmful to occupants if they were discharged indoors. Thus, routing relief valve discharge to an open receptacle aligns with safety standards and effective plumbing practices.
