We recommend KOHLER® Drain Treatment for the best results. If using a different type of drain treatment, follow the manufacturer’s directions for use.
Remove as much standing water as possible. Pour entire contents of the package into the clogged drain. Allow to work overnight if possible. Flush with hot water.
Add 4 ounces of product for each inch of drain pipe diameter. Add at lowest water-use period for best results. Continue daily until system flows freely, then add every other week as a preventative maintenance.
