What is the minimum size of the water supply inlet for a pedestal urinal?

1 inch 1/2 inch 3/4 inch 5/8 inch

Correct Answer:

1 inch

Explanation:

The minimum size of the water supply inlet for a pedestal urinal is typically 1 inch. This standard supports the optimal functionality and efficient flushing of the urinal. A 1-inch inlet allows for sufficient water flow, ensuring that the urinal operates effectively to clear waste and minimize clogs. While smaller inlet sizes, such as 1/2 inch, 3/4 inch, or 5/8 inch, may technically supply water, they can lead to inadequate water flow which may result in poor urinal performance, such as inefficient flushing or increased risk of blockages. Therefore, adhering to the standard of a 1-inch inlet ensures that the urinal meets expected performance criteria in terms of water supply and operational efficiency.
