What is an acceptable material for piping in a septic system?

Vitrified clay is an acceptable material for piping in a septic system due to its durability and resistance to the chemicals and conditions typically found in wastewater. The vitrification process strengthens the clay, making it less porous and more resistant to cracking and infiltration of external water. It also helps prevent corrosion, which is beneficial in the moist, underground environment of a septic system.

When considering the performance and longevity of materials used in septic systems, vitrified clay offers an effective balance of strength and longevity, helping to ensure that the system functions properly over time. Other options may not provide the same level of resistance to deterioration over long periods in a septic environment.
