In short, yes. As a rule, it’s best to avoid disposing of anything in your septic system that you can just as quickly put in the trash. Keep in mind that your system is not a garbage disposal. Solids accumulate in the tank and will eventually need to be pumped out.
Avoid putting coffee grounds, food scraps, and other food items down the drain. Additionally, grease and cooking oils should never be disposed of in this way, as they contribute to scum buildup in the septic tank. It’s important to note that garbage disposals can increase the amount of solids in septic tanks by up to 50%, making them unsuitable for use with septic systems.
Use the same common-sense approach in your bathroom. Don’t dispose of plastics, tampons, paper towels, disposal diapers, kitty litter, or condoms in your toilet. You will only want to flush wastewater and toilet paper down the toilet.
