End-of-season maintenance is an important part of keeping your RV and its systems in good working order. A key step in preparing your RV for a long winter is winterizing your Truma AquaGo instant water heater. The Truma AquaGo can be fully winterized without any chemicals or special tools, thanks to our Easy Drain Lever.

Step 1: Turn off your Truma AquaGo and allow the unit to cool completely.

Step 2: Depressurize the Truma AquaGo by turning off the pump or incoming water supply and opening all hot and cold water fixtures.

Step 3: The unit should be placed in „Bypass“ mode in accordance with the manufacturer’s instructions.

Step 4: Release the yellow „Easy Drain Lever“ to empty the mixing vessel.

Step 5: Swing the yellow lever down as far as possible to eject the filter cartridge, allowing the water to drain completely.

Step 6: We recommend storing the filter cartridge separately while the system is winterized.

Your Truma AquaGo is now winterized!

We do not recommend the use of high-pressure air or antifreeze solutions when winterizing the Truma AquaGo. Antifreeze fluid should only be used with an installed bypass kit, refer to the complete manufacturer‘s manual for more details.

Other Maintenance 

We recommend decalcifying your Truma AquaGo annually. Make this a part of your end-of-season checklist with easy-to-use Truma AquaGo Decalcification Tablets 

If you plan on traveling in the winter months, we recommend purchasing a Truma AquaGo Electric Antifreeze Kit to keep your Truma AquaGo frost-free, even in stand-by mode, without using propane.
