What is the minimum opening spacing for perforated tile on center?

The minimum opening spacing for perforated tile on center is set to facilitate proper drainage and to optimize the functionality of the sewage system. When spacing is at a minimum of 3 to 5 inches on center, it allows for adequate water flow while also minimizing the risk of clogging from soil or debris. This spacing ensures that the system can efficiently handle wastewater without overwhelming the tile's ability to move it away from the area, allowing for the necessary percolation into the surrounding soil.

Choosing a spacing that falls below this range could compromise the system's effectiveness. Closer spacing may lead to unnecessary redundancy, where tiles may provide overlapping drainage, and could increase the cost without increasing efficiency. Ensuring that the spacing adheres to the 3 to 5-inch guideline results in a balanced system design that maximizes drainage efficiency while maintaining structural integrity.
