What is the reason that P-type or S-type traps are fitted on the sinks in a head?

🔍 Key Concepts

• Function of P-type and S-type traps in plumbing systems • Purpose of a water seal in sanitary piping • Difference between flow control, siphoning, and gas sealing in drains

💭 Think About

• Think about what problem would exist in a head compartment if there were NO trap under the sink drain. • Consider what stays inside the bend of a P-type or S-type trap during normal use, and what that prevents from moving back up the pipe. • Which answer choices describe effects related to pressure surges in pipes versus effects related to odors and air movement from the drainage system?

✅ Before You Answer

• Identify which option specifically mentions blocking gases/odors rather than changing water flow speed or pressure. • Recall that traps are designed to always retain a small amount of standing water in the bend—ask yourself what that standing water is protecting you from. • Eliminate any choices that mainly deal with erosion, water hammer, or siphon strength, and focus on the one that deals with separation between the drain and the compartment.

What is the reason that P-type or S-type traps are fitted on the sinks in a head?

to reduce water velocity and minimize erosion

to create a strong siphon effect

to provide a cushion of water to reduce the effects of water hammer

to provide a seal against sewer gas rising into the compartment
