What is another term used for "island venting"?

Island venting refers to a specific plumbing design method that is typically applied in kitchen fixtures where the sink is located on an island without adjacent walls for the installation of conventional venting methods. The term "loop venting" is synonymous with island venting, as it describes the technique whereby the vent pipe forms a loop to connect back to the drainage system and effectively vent the trap of the sink. This design allows for the venting of gases and the prevention of siphoning in situations where traditional vertical venting cannot be utilized due to the sink's location.

Understanding loop venting as another term for island venting is crucial for plumbing design practice, especially with regards to ensuring compliance with plumbing codes and maintaining proper functionality in kitchen environments. Loop venting is designed to maintain air pressure in the drainage system, enabling efficient drainage while also preventing trap seal loss.
