Although the only requirement before pumping is that you schedule a service visit shortly before the pumping we do recommend using a certified Jet pumper company to pump out your Jet tank. The reason you should not use any pump company is that your Jet system has the unique BAT® Media that can be severely damaged during a pump out if it is not properly cleaned before pumping. A certified pump company will have the necessary tools to clean your media avoiding costly repairs and ensuring the optimum treatment performance from your Jet system.
