There are many ways to clean out sewer pipes and hydro jetting or also called hydro evacuation is a non-destructive method. Hydro jetting uses high pressure water flow to remove grease and other debris that will clog your commercial sewer pipes. Hydro Jetting done properly can remove a large amount of what is clogging your pipes. It works from the downstream portion of the system and moves upward working it’s way through the sewer system.
