Which type of trap is typically used in kitchen sinks?

The type of trap typically used in kitchen sinks is the P-trap. This design is favored because it effectively minimizes odors from the sewer system while ensuring that sink drainage is efficient.

The P-trap works by holding a small amount of water in its bend, which creates a seal that prevents sewer gases from escaping into the living space. This is crucial in a kitchen where food particles and grease are often present, as these can contribute to clogging and foul odors if not managed properly.

Additionally, the P-trap is relatively easy to install and access for maintenance, which is an important factor in kitchen plumbing where clogs can occur more frequently due to food waste. Other types of traps, like the S-trap, are not typically used in kitchen sinks due to their vulnerabilities in creating siphonage issues, while drum and bell traps are less common in residential settings and are more often found in specific applications like floor drains.
