A septic system is a living digestive system. Chemical drain cleaners kill the micro-biology that breaks matter down — a strong odour means there’s too little life left to do the work.
Apply 250 ml per drain and toilet, weekly. This keeps the system clean and odour-less from top to bottom, keeps it healthy and reduces blockages.
If you can access your septic tank, add 5 litres (min) per 1 000 litre tank, monthly. This limits sedimentation and blockages.
Use a spray pack with 100% DMO, spraying for the first few days with frequent inspection. Nature’s capacity then digests the imbalance of the spill.
