YES! Harmful substances such as grease, liquid wastes (pesticides, household chemicals, paints), oils, coffee grounds, and heavy creams should not be poured down the drain. To maintain the health and functionality of your septic system, it's crucial to avoid flushing non-biodegradable materials. This includes items like feminine hygiene products, baby wipes, and other disposable items that are not designed to break down easily. Flushing these items can lead to clogs and blockages in your septic system, potentially causing costly repairs. Additionally, limiting the use of your garbage disposal helps prevent the unnecessary accumulation of solid waste in the septic tank.
