What is the branch size for a plaster sink?

The branch size for a plaster sink is typically 2 inches. This size is selected based on plumbing code requirements and practical considerations for drainage. A 2-inch branch provides adequate flow capacity, helping to prevent clogs and ensure proper drainage for the sink's waste.

In the context of plumbing systems, particularly those involving fixtures that may experience a high volume of waste, a 2-inch pipe is standard as it can efficiently handle the necessary drainage without risking backflow or slow drainage issues. It strikes a balance between being large enough to accommodate the expected waste and water flow while not being unnecessarily large, which could complicate installation and increase costs.

Understanding this standard allows plumbers to ensure that fixtures like plaster sinks operate effectively within the overall plumbing system.
