Quick, easy and simple just the way everyone likes it. BacPac was developed for those drains that you want to treat quickly and not have to worry about using too little or too much product. BacPac comes in pre-measured packets with enzyme-producing bacteria to keep drains clear of grease and scum. Simply empty the packet into the drain and add warm water. This Earth Smart® Certified formulation will then foam to make sure the entire surface area of the pipe is treated as the bacteria and enzymes break through and degrade the grease and biofilm.
