Georgia Septic Installer Practice Test

What is the minimum tensile strength required for a fiberglass tank?

1. 10,000 PSI

2. 12,000 PSI

3. 14,000 PSI

4. 16,000 PSI

The correct answer is: 12,000 PSI

The minimum tensile strength required for a fiberglass tank is 12,000 PSI. This specification is crucial because it indicates the tank’s ability to withstand various stresses during operation, including pressures caused by the weight of the contents and external forces such as soil or water pressure. Fiberglass tanks are often used in septic systems because of their lightweight properties and resistance to corrosion, making it essential that they possess adequate strength to ensure durability and safety over time. Complying with the 12,000 PSI tensile strength standard helps prevent failures that could lead to leaks or environmental contamination, aligning with safety and regulatory requirements in septic system installations.
