🔍 Key Concepts

• Steam trap operating principles (how condensate is discharged while steam is retained) • How an inverted bucket trap is constructed compared with an upright bucket or "P" trap • The orientation of the bucket and discharge valve inside the trap body

💭 Think About

• Look closely at the shaded bucket-shaped part: is its open end facing up or down, and what does that tell you about the trap type? • Trace the path from the inlet at the side of the body to the outlet at the top: how does the internal mechanism use buoyancy to open or close the discharge? • Compare what you see in the drawing to the typical plumbing shape of a "P" trap—does this internal cross‑section match that kind of simple bend in piping?

✅ Before You Answer

• Identify the orientation of the bucket (open end up vs. down) and relate that directly to the name choices. • Confirm where the valve and seat are located (top or bottom of the unit) and how the bucket connects to them. • Verify whether a true "P" type trap would normally show an internal moving bucket at all, or simply a fixed U/P-shaped water seal.
