What is the minimum pipe size required for a general wall hydrant?

The minimum pipe size required for a general wall hydrant is typically 3/4 inches. This size ensures that the hydrant can supply an adequate flow of water while still maintaining appropriate pressure levels for common uses such as irrigation and general cleaning. A 3/4-inch line provides a balance between sufficient water delivery and compatibility with standard hydrant fittings, making it a common standard in plumbing practices. Choosing a pipe size smaller than 3/4 inch could restrict flow and potentially lead to pressure loss or inadequate water supply, which is why it's crucial to adhere to this minimum standard for wall hydrants.
