What does the enzyme interceptor do?

  1. Filters solid waste

  2. Breaks down grease chemically

  3. Increases water flow

  4. Reduces water usage

The correct answer is: Breaks down grease chemically

An enzyme interceptor does not filter solid waste. This is typically the job of a solids interceptor. Similarly, it does not increase water flow or reduce water usage. These are typically functions of water filters or water conservation systems. Instead, the enzyme interceptor's main purpose is to break down grease chemically, often using naturally occurring enzymes, in order to keep grease from getting into the sewer system and causing costly blockages and overflows.
