Drain Tile Piping typically ranges in sizes from 2” diameter to 18” diameter. 4” diameter is standard sized piping for foundation drainage systems. Piping is primarily constructed from plastic (PVC, ABS) or clay. PVC Drain Tile typically comes in 10 ft.

How do you calculate drain size?

Divide the pipe’s internal diameter by 2. For example, if the pipe has an internal diameter of 0.1 meters: 0.1 ÷ 2 = 0.05 m This is the pipe’s radius. Square this radius: 0.05² = 0.0025 m². Multiply the result by pi, which is approximately 3.142: 0.0025 × 3.142 = 0.007855 m².

What size should my main drain be?

Sewer drains from laundry sinks or washing machines are 2 inches in diameter and those from sinks in the kitchen, bathroom or powder room generally use a 1.5-inch pipe. The main sewer pipe leading to the septic tank or public sewer is usually 4 inches.
