Many times when pumping a septic tank, we recommend hydrojetting your inlet and outlet lines. Throughout the years, grease will build up in your pipes which will cause septic back up. Often times, even after we have pumped out a septic tank, the water will not flow freely because the pipes are clogged with grease. Hydrojetting is a great option to make sure your lines are clean and you water runs freely. However, if you do not regularly pump and hydrojet your septic tank, it becomes harder to insure that all of the grease will be dislodged by the first hydrojetting session. Therefore, we recommend hydrojetting your lines every time you get your septic tank pumped.
