1996 Airstream B Van

[midwestmn]

How to winterize my B Van...........I have been told to pump out all water, drain hot water tank and add 5 gallons of anti freeze to the water tank and pump through the entire system,, with water replaced in the hotwater tank with the antifreeze because when you fill the water tank it always goes to the hotwater tank first

Thank you for all replies........

I do not know on your model- but mine has ‘bypass’ valves that allow the system to bypass the hot water tank. Then you drain the tank.

I suggest going to the Airstream document archive, get the manual and read up.

Upon looking closer, I did not see a manual listed.
Assuming you have a B190, check here:

I found this from a 1998. Looks like the Bypass is an option...

Winterizing, Procedures

1.​Open faucets and prop toilet open.

2.​Open all drain valves.
a.​Water tank: Under vehicle in rear. Access drain valve behind tail pipe exhaust.
b.​Cold water line drain: Access through rear double door next to spare tire.
c.​Hot water line drain: Access through rear double door next to spare tire.
d.​Water heater. Drains out plug on the lower face of water heater.

3.​After water quits draining shut valves.

4.​Attach a length of hose to the intake side of water pump and insert into RV antifreeze container. This may be diluted. Follow directions on container.

5.​Turn pump on and operate until antifreeze is apparent at all faucets and the toilet.

6.​Power a cup of the RV antifreeze down each sink and shower drain.

7.​Dump holding tanks.

8.​Remove batteries and store where there is no danger of freezing. Bring up to full charge about every six weeks with a trickle charger.

9.​Remove any items from unit that may be damaged by freezing, such as canned goods and cosmetics.

Note:​If you wish to bypass your water heater in order to cut down on the amount of antifreeze necessary, you may purchase a kit for this purpose from your dealer.
