How far above an underground 2000 gallon WC tank must the relief valve be piped?

• A. 5 ft
• B. 7 ft
• C. 9 ft
• D. 12 ft

Answer: (B)

The requirement for the relief valve to be piped at a height of 7 feet above an underground 2000 gallon water circulation (WC) tank is grounded in safety and operational protocols for tank systems. This height ensures that any potential discharge from the relief valve is elevated enough to prevent backflow into the tank, which could inadvertently create a hazardous situation. By maintaining this specified elevation, it helps to mitigate risks associated with pressure buildup within the tank, ensuring that the relief valve operates effectively when required. Additionally, placing the valve at this height allows for easier visibility and accessibility, which is important for maintenance and inspections without compromising safety. The other height options either do not meet established industry standards or create unnecessary complications regarding maintenance and potential safety hazards. Therefore, 7 feet is deemed the optimal height that balances safety with functional requirements.
