The Knock Out Biological Drain Treatment (1 Litre, 50090278) is an eco-friendly, enzyme-based maintenance solution designed to safely break down organic waste, grease, fats, and food residues within domestic and commercial drainage systems. Unlike harsh chemical cleaners, this biological treatment harnesses natural bacteria and active enzymes to actively digest organic buildup, preventing slow drains and foul odors at the source. It is completely biodegradable and safe for use across all standard pipe materials, plumbing fixtures, and septic tank systems without generating heat or harmful fumes.
 
This treatment is ideal for regular dosing in kitchen sinks, shower drains, and high-use hospitality plumbing networks to proactively prevent grease accumulation and organic blockages before they develop into full pipe clogs. By utilizing specialized non-pathogenic bacteria that colonize pipe walls, it provides continuous, long-term cleaning action that keeps drainage networks functioning smoothly and odor-free between manual interventions.
 
For best results, the product is typically poured down the drain at the end of the day or during periods of low water usage, allowing the active enzymes and bacteria maximum contact time to break down accumulated waste deposits. Essential for preventative plumbing care and sustainable facilities management, this biological treatment offers a safe, reliable, and environmentally responsible way to maintain healthy drainage systems.
