How should the discharge from a reverse osmosis system enter the drainage system?

Directly into a sink
Separate trench
Side by side in the same trench
Via a dedicated pipe

The correct answer is: Side by side in the same trench

The correct method for discharging waste from a reverse osmosis system is through a dedicated pipe. Using a dedicated pipe ensures that the waste stream from the reverse osmosis system is kept separate from other plumbing fixtures, preventing potential contamination and improving the overall efficiency of the drainage system. Discharging directly into a sink can lead to backflow issues and contaminate potable water sources with waste. Additionally, having the discharge enter via a separate trench could create unnecessary complications in the plumbing layout, such as increased costs and potential for leaks. By using a dedicated pipe, the system maintains regulatory compliance and adheres to best practices for plumbing installation. This method also simplifies maintenance and monitoring of the reverse osmosis waste stream, ensuring proper handling at all times.
