Keep the flow going, with a drain maintainer that restores normal flow rate to slow drains. Reduces the demand for further downstream waste processing. Non-toxic, non-corrosive, non-caustic, and safe for general commercial and industrial use. Drain cleaner uses a multiple-strain blend of bacteria formulated to attack the soils commonly associated with build-ups in pipes and grease traps. Helps maintain your drains, grease traps, and septic fields. Regular use will decrease the frequency of need to clean out grease traps and eliminate slow-flowing drains. Automatic application through a dispensing pump is recommended for best results.
