Sewer-Heat: High-Heat Activated Alkaline Sewer & Drain Opener

Fats, oils, and grease (FOG) from households, restaurants, food processing plants, and other grease-producing establishments accumulate in sewer lines, causing issues like backups, sanitary sewer overflows (SSOs), unpleasant odors, and increased maintenance costs.

When Sewer-Heat is added to water in a drain or sewer, it generates intense heat and turbulence, effectively liquefying, dissolving, and loosening organic matter and other materials that clog drains and sewer lines.

    Use of this drain opener generates considerable heat which may cause eruption of hazardous liquid contents. NEVER use a plunger with this product. Add slowly to drain or manhole. Never look into drain after treating.

    Place a bucket or other deep container over drain opening after treatment. Do not use in combination with or directly after treatment with acid type drain openers, as it will react violently. Do not enter treated sewers until they have been thoroughly flushed out with water.
