What is the recommended size of the waste outlet for floor drains?

The recommended size of the waste outlet for floor drains is typically 2 inches. This size strikes a balance between effective drainage capacity and preventing clogs. In many commercial settings, floor drains need to accommodate varying volumes of waste water, so a 2-inch outlet is often chosen because it allows for efficient drainage while being manageable in terms of installation and maintenance.

Larger outlets could potentially lead to complications in some environments, such as increased costs for piping and fittings, as well as greater difficulty in maintenance, while smaller outlets may become easily clogged or insufficient for high water flow scenarios. Therefore, a 2-inch size is generally seen as both practical and effective for the intended use in ensuring that floor drains operate efficiently.
