If you're having a pressure problem with your water jetter, it could be the unloader. Learn how to diagnose an unloader problem and replace it if necessary. Dave Dunbar and Dave DW Wintruba from General Pipe Cleaners discuss diagnosing and solving a low or fluctuating pressure problem. This covers General's JM-1450 electric jet, or the JM-2900, JM-3000, JM-3055, JM-3080 gas jets, or the JM-2512 Typhoon water jet.

General Pipe Cleaners' water jetters are ideal for clearing soft stoppages and ice from clogged drain lines and sewer lines. They use a stream of high-pressure water that hits the stoppage and flushes it away. The thrust of the nozzle drives the hose down the line and gives you wall to wall cleaning action. You’ll find plenty of uses for General’s sewer jetters – in restaurants, hotels, hospitals, shopping malls, factories, schools, apartment complexes and septic systems everywhere.

General’s Jet-Set line of water jetters gives you new drain cleaning tools to use on some of your toughest sludge and grease-based stoppages. Our sewer jetters do a more thorough job of clearing drains.
