10.
Turn the water pump on and allow it to prime. Close galley sink faucet once you see pink antifreeze coming out. Close the shower sink faucet once
you see pink antifreeze coming out.
11.
Next, move the galley and shower faucets to the hot side. Close hot galley sink faucet once you see pink antifreeze coming out and have filled the
p-trap. Close the hot shower sink faucet once you see pink antifreeze coming out and you have filled the p-trap.
12.
Open the toilet valve. Ensure antifreeze flows into the toilet and flush until you see pink antifreeze coming out.
13.
If the water pump loses its prime in this process, you will need another container of antifreeze to complete the winterizing process.
14.
Turn the water pump off and open galley sink faucet to release back pressure.
15.
Dump additional antifreeze into the shower drain until the p-trap is full. You may also consider adding extra antifreeze to the toilet cassette and
waste water tank by dumping into the toilet, shower or galley sink directly.
16.
To winterize the waste water tank hose, open the hose valve until you see pink antifreeze coming out of the waste water discharge hose. Close the
valve when complete.
17.
Open the fresh tank drain line until antifreeze flows out.
Other Methods of Winterizing
Erwin Hymer Group NA only recommends the winterizing method outlined above using RV antifreeze.
HOWTO: De-Winterizing
If you winterized only for a short time (less than a week) you can complete this winterizing procedure without the use of bleach. Otherwise, if winterizing for a
longer period you will need 2 gallons of fresh water and 1 cup of fresh bleach. (Bleach loses its potency over time; always start with bleach that is less than 6
months old.)
1.
Use the open end of the pipe, connected to the 3-way valve located underneath the podium floor, by accessing it through the hatch under the table.
2.
Using the same steps in the ‘Winterizing’ section
, pump the mixture of water and bleach through the plumbing system.
3.
Drive around for at least an hour. Let it sit for a couple more hours after the drive.
4.
Repeat step 2 using water (no bleach).
5.
Reverse the water heater bypass valves and send fresh water through the hot water tank.
6.
Finally, complete the de-winterizing procedure by using fresh water through the city fill connection. Remember to switch the 3-way valve position such
that it is no longer in the winterizing position.
