I have a septic tank that drain real slow when I wash clothes or take a shower it bubles like its going come up in the kitchen sink can I use this

If you're experiencing a back-up, it is advisable to snake the lines prior to using the Zep Root Kill .To treat leach line pipes, add 2 pounds of product to the distribution box located between the septic tank and the leach lines. To achieve effective root control in the leach lines it is necessary to transfer the product from the septic tank to the leach lines. A clean-out plug opening may need to be installed if the distribution box does not have an opening leading to the leach lines. Thank you for your inquiry.
