A powerful blend of selected enzymes and microorganisms that efficiently and safely reduce the sticky greasy waste evacuated into drainage systems, causing blockages. Drain Solution improves flow rates and prevents odour problems in the small-bore pipes flowing from sinks, baths, showers and kitchen macerators. Bio Productions Biologicals contain species of micro-organisms/bacteria that are commonly found in the digestive tract and in soil. The bacteria secrete a cocktail of enzymes aiding the breakdown of organic matter. As such, the micro-organisms found in the biologicals are classed as probiotic.
