🔍 Key Concepts

• Look at how item 4 connects to many separate branches in the system. • Think about what a manifold does in piping diagrams versus what a single suction line does. • Consider whether item 4 is showing a whole system or just one part that distributes flow.

💭 Think About

• Does item 4 appear to collect or distribute flow from/to several smaller lines? • If you follow the arrows at item 4, are they indicating multiple outlets from one common body, or just the direction in a single pipe? • Which choice describes a component that serves as a central point for several branch lines in a piping system?

✅ Before You Answer

• Verify whether item 4 has multiple arrows/ports indicating several connections. • Check if the surrounding symbols show this component feeding different branch lines rather than just one run of pipe. • Confirm that the label for item 4 seems to represent a single piece of equipment, not an entire system such as all bilge piping.
