What is the minimum diameter size required for the bypass around the check valve?

• A. 1 inch
• B. 2 inches
• C. 3 inches
• D. 4 inches

Answer: (B)

The minimum diameter size required for the bypass around the check valve is recommended to be 2 inches. This size ensures adequate flow and pressure management in the system, allowing for the proper operation of the check valve without creating excessive resistance or back pressure. A bypass system is essential for allowing fluid to flow around the check valve when it is closed, thereby maintaining system pressure and preventing potential damage or inefficiencies. Additionally, a 2-inch diameter bypass provides a balance between minimizing pressure loss and ensuring that sufficient flow can be maintained, which is critical for the effective operation of sprinkler systems. Smaller diameter bypasses might not handle the volume needed effectively, while excessively large bypasses could lead to unnecessary costs and installation complexity. Therefore, using a 2-inch bypass meets industry standards and operational requirements in most sprinkler fitting applications.
