New York City Plumbing Code 2022 Key Changes in Pipe Hanger Spacing Requirements - Changes to Drainage Fixture Unit Loads for Unlisted Fixtures
The 2022 New York City Plumbing Code brought significant changes to how unlisted fixtures are handled. Previously, there wasn't clear guidance for these fixtures, leaving plumbers and inspectors to make their own judgments. The new code now mandates that the drainage fixture unit load for unlisted fixtures be determined by the size of their drainage outlet. This means that the code provides a more standardized approach to determining the flow rate of water for these fixtures, which can help to ensure that the plumbing system can handle the volume of water being discharged.
The code also requires the minimum trap size for unlisted fixtures to be at least as big as the drainage outlet. This rule is intended to prevent clogs and other problems by ensuring that the trap can effectively collect and retain water, preventing odors and gases from entering the building.
Another interesting change is that the code now assigns a drainage fixture unit load of one-half to Clearwater waste receptors. This is a specific type of waste receptor that is often used in commercial kitchens, and the new code recognizes that these receptors generally handle less water than other types of fixtures.
The changes made to the code in 2022 are part of a broader trend toward increasing the standardization and rigor of plumbing regulations. The code is constantly evolving, with revisions often based on advancements in plumbing technology, material science, and best practices.
