For when it goes from bad to worse! These kits provide a safe, non-toxic solution for most failing or failed systems. The combination of products in the kit break down solids, adds oxygen to the system, dissolves the bio mat, and adds bacteria to jump start your system. This will restore your drain fields ability to absorb wastewater effluent. Please be advised that proper application of the kit requires access to your septic system distribution box, pumping of the septic tank and possible cleaning of the drain lines. We suggest that you work with your local septic system service provider when using this product.
