To what depth should a drain pipe be buried to ensure proper function?

The correct depth for burying a drain pipe is typically recommended to be 24 inches. This depth helps ensure that the pipe is below the frost line, which varies by geographical location but is generally around 30 inches in colder climates. By placing the pipe at this depth, you reduce the risk of freezing during harsh winter conditions, which can lead to blockages or ruptures. Additionally, 24 inches allows for adequate soil coverage and provides protection from surface activities and mechanical impact that might occur above ground.

Choosing a depth of 24 inches balances the requirements for frost protection and the practicalities of installation without being excessively deep, which could complicate installation or maintenance.
