No more than how many fixtures may be on a 1/2 inch fixture branch?

• A. 2 fixtures
• B. 4 fixtures
• C. 3 fixtures
• D. 5 fixtures

Answer: (C)

A half-inch fixture branch is sized to carry only a limited flow to multiple fixtures, so you must limit how many fixtures it serves to avoid pressure drops that leave fixtures inadequately supplied. In practical sizing, three fixtures is the maximum that can be reliably fed from a 1/2 inch branch while maintaining usable pressure at each fixture. If you need to serve more fixtures, you’d upsize the branch or run additional branches from a larger main so each fixture still gets adequate flow.
