Water jetting is a method we use to clear blockages in pipes and clean pipes of debris. We get a call to action from apartment complexes, mobile home parks, or other plumbers. We use water jetting in several different situations. When manholes are clogged with sewage and a blockage is in the main sewer it is a great way to go long distances up to 600 feet. Most mechanical tools only are effective up to 100 feet. Another important customer of ours is restaurants. The kitchen drains leading to the grease trap is often times restricted with an accumulation of grease. It sticks to the sides of the pipes. Regular auger tools cut through the grease but do not break it up enough and flush it away. It flops around and then lays back down unless it is jetted.
