Hydro-jetting is a process that uses high speed / high pressure water to clear blockages in pipe systems and is typically the first approach to clearing blocked lines. Barring the possibility of a collapsed line, hydro-jetting will solve the problem and thereafter routine maintenance will keep the lines free and functioning properly. Maintenance of this sort will go a long way toward minimizing eventual blockages that could result in a line breakage requiring more drastic and expensive repairs.
