Before backfilling, sacrificial anodes should have what removed?

Before backfilling, it is essential for sacrificial anodes to have protective coatings removed. Sacrificial anodes are designed to corrode in place of the metal structure they protect, such as a tank. If they are covered with a protective coating, it can prevent the anode from effectively coming into contact with the soil, which is crucial for its cathodic protection capabilities. This removal allows for the anode to perform its function properly, ensuring that it can adequately protect the underground storage tank from corrosion.

The reason waterproof packaging materials are not pertinent in this context is that they do not directly affect the anode's ability to function in the soil. Instead, ensuring the anodes are free from materials that might hinder their effectiveness is critical for maintaining the integrity of the UST system.
