What information must be included on the outlet side of a septic tank?

The correct information that must be included on the outlet side of a septic tank is the name of the manufacturer and the date manufactured. This is essential for several reasons.

Firstly, having the manufacturer’s name helps in identifying the source of the tank, which can be crucial for service, warranty claims, or when seeking specific parts or maintenance advice. Secondly, the date of manufacture is important as it provides insight into the age of the tank, which can affect its performance and lifespan. Knowing this information can help homeowners and professionals assess the need for repairs or replacement based on the tank's age and expected longevity.

While installation cost and warranty information (which are related to the overall ownership and use of the septic tank) and size and empty weight are useful pieces of information, they do not specifically pertain to the required labeling on the outlet side of the septic tank. Thus, the key criteria for labeling focuses on the manufacturer details and the date of manufacture.
