According to typical build specifications, what is the most accurate statement regarding 4" drain tile installation?

The statement that footing drains shall be 4 inches is accurate according to typical building specifications for drainage systems. Footing drains, or drain tiles, are critical in managing groundwater around a foundation. A 4" diameter drain tile is commonly used for effectively handling the volume of water that may accumulate due to rainwater or groundwater. This size is optimal for ensuring adequate flow and reducing the risk of clogs, which is essential in maintaining the integrity of the structure and preventing water damage.

The choice of a 4" diameter helps to strike a balance between sufficient capacity and manageable installation practices. Other diameters, while they may exist, are less common for this specific application and may not comply with local building codes or recommendations for optimal performance in residential construction.
