You need to feed your machine with rotten tomatoes every now and then while taking care of your septic tank. Perhaps another alternative way to fix and restore your septic tank is to use old tomatoes in your fridge if flushing down any yeast is not going to work. Through doing this, by grinding them down into your garbage system, you can produce bacteria in your septic system.
In order to provide your septic tank with healthy bacteria and break down waste, an average of 3 to 4 tomatoes every 4 months would be enough. If you do not have any waste disposal available at home and you need a way to get rid of the tomatoes, you can smash them and place them in a bag so that you can pour these tomatoes for the same cleaning results down the toilet.
You should stop placing such chemicals and things in your tank while cleaning and repairing your septic tank. You need to note that all sorts of raw or fried meat, grease, cooking oils and fats should not be thrown away.
