🔍 Key Concepts

• Identify the symbol used for item 3 in the piping diagram (what type of valve or fitting it represents). • Recall how a check valve vs. a stop valve vs. a flow control valve affects the direction of flow in a system. • Consider whether the direction of flow through that item depends on system pressures or is fixed by the design of the component.

💭 Think About

• Look closely at the graphic symbol for item 3. Does it show a moving element that blocks flow in one direction and opens in the other, or is it a simple open passage? • Ask yourself: if the pump were reversed or pressures changed, would this component allow reverse flow or prevent it mechanically? • Compare the symbol at item 3 with the symbols at items 2a, 2b, 6, and 7. Which ones clearly allow flow both ways, and which one is designed specifically to stop backflow?

✅ Before You Answer

• Confirm what standard piping symbol item 3 matches (e.g., check valve, globe valve, gate valve, relief valve). • Verify whether that component’s internal construction allows, prevents, or controls reverse flow regardless of pump suction or discharge pressure. • Make sure you are not confusing a pressure‑dependent relief valve with a directional check valve when choosing between the options.
