How to Dewinterize the T@B 400

Ready to Dewinterize the T@B 400

So, you winterized your 400 and allowed it to rest during the cold weather.  Perhaps, you read my post, Winterized our Camper Water System.  Now, you are ready to get out there and go camping again.  Fortunately, it is quite easy to dewinterize the T@B 400.  For the water system, you basically just flush out the antifreeze.

Adding Water to the System

The 400 was thoroughly drained to winterize, but now is the time to add water back to the system.  First, ensure the drain to the fresh water tank is closed.  (It is located under the camper, near the wheel on the driver’s side.)  Fill the fresh water tank about half full.   The tank holds 30 gallons, so half filled is approximately 15 gallons.  Do not leave the camper unattended while adding the water as damage can occur if it is overfilled.

It is best to flush the antifreeze using the water holding tank and pump because it enables the identification of leaks in the system.  If the pump continues to run while faucets are closed, there is a leak somewhere.

 

Flushing the Antifreeze

Next, turn on the pump.  Then, one at a time, turn on each water source and let it run till you can no longer see any pink antifreeze.  Start with the cold water faucets in the kitchen and bathroom sinks, shower, and outside shower.  Then flush the toilet until pink antifreeze is no longer visible.  Lastly, turn on the hot water in kitchen sink, then bathroom sink, shower, and outside shower.

Once clear water flows through all water sources, you have flushed the antifreeze from your fresh water system.  The antifreeze is now in the black and grey holding tanks and is ready to be dumped into a sewer or dump station.  Do not allow it to drain into your lawn as it will kill plants.

 

Adjust the Bypass valve

The last step for the fresh water system is to adjust the bypass valve.   It kept the antifreeze away from the hot water heater on Bypass.  It needs to be set to normal to fill the hot water heater.  Move the lever on the Bypass Valve from “Bypass” to “Normal”.

Other Steps to Prepare for Camping

The detailed steps above merely addresses preparing the water system for camping.  Owners should also check tires, battery, propane tank, condition of safety chains, tightness of the hitch, proper seating of windows and doors, and condition of the camper exterior.

Additionally, wheel bearings should be lubricated once every year or at least every 10,000 miles.   See our post, Wheel Bearing Maintenance-A Safety Necessity.

Lastly, NüCamp recommends owners to sanitize the fresh water system annually.  A good time to do this is during dewinterization.   A link to the nüCamp manual follows, T@B 400 Manual.   The section on sanitation of the water system is on page 23.
