Note: The above tables are for typical freezing of static water at 68oF in Schedule 40 steel pipe.  Higher temperatures will require additional injection and waiting periods.  Plastic pipe will take up to 3 times longer. Refer to Operating Manual for detailed instructions.  For freezing applications on pipes larger than 8" (203mm) I.D., please contact customer service at 1(800) 437-1146 for information.
