Mrs Martin’s Probiotic Tank&Drain Powder 500g


Stinky drains? Pit latrine? Foul greywater? Septic tank? Grease build-up? TANK&DRAIN solves it all. The indigenous microbes in this powder actively biodegrades organic dirt and breaks down build-up of grease, fats and oils. That means odours are controlled and blockages are eliminated.

Daily small doses of the product will have the following benefits for pit latrines, mobile toilets and septic tanks: ➢ reduces bad odour ➢ bioremediates human waste ➢ lowers tendency for waste to leach to ground water and cause contamination ➢ reduces environmental pollution ➢ lowers need for sludge pump-out because solids are liquefied and then digested ➢ reduces propensity for flies.

Daily small doses of this product will have the following benefits for greywater: ➢ reduces bad odour ➢ lowers growth and transfer of pathogenic disease causing organisms ➢ produces relatively clean water to be used for toilet flushing and irrigation.

Daily small doses of this product will have the following benefits for fat traps and kitchen drains: ➢ reduces bad odour ➢ eliminates drain blockages because fat is broken down

Probiotic Tank&Drain Powder

Great product for eliminating smelly odours in drains. I also use it in shower and basin outlets that are not in regular use to keep the unpleasant odours that might develop in the stagnant water, at bay.
