Winterizing a Winnebago View 2006 23H (Air)
Using the Air Blow out Method
Posted to View navion yahoo group Oct 2007
Marty,
If you're able to follow these instructions, leaving out blowing the
lines out, you'll fine.
******************************
My thoughts!
I use the blow out method with a max of 40 psi. Have done this for
years on 2 Rialtas' a VIEW and now a NAVION. Guess I'm lucky!
I do this to avoid the terrible anti-freeze odor that stays in the
plumbing in the spring time.
Hear is how I do it. First I open all the faucets, don't forget the
shower (inside and out). Drain the HWT by removing the dran plug and
opening the relief valve. Replace drain plug after putting pipe dope
on threads and close the relief valve. Then turn the by-pass valve on
the HWT to prevent air from going into the tank during the blow-out
process. Now I turn on the water pump and let it run until no water
comes out of faucets. Flush toilet until it's dry. Now I remove the
filter bowl on the water pump and empty the water from it and replace
it. Take off my water filter canister, under the galley sink, and
install the "T" plug. Pour water carefully out of filter, don't turn
it upside down, only need to pour half to 3/4 from it. Cap the filter,
if it doesn't need replacing, put it your home freezer.
Now, I put the blow-out adapter on the city water inlet and connect
compressor and blow out plumbing. Turn all but one cold faucet off,
make sure air is coming out of it. Then I close and open the other
cold water faucets until all I get is air. Repeat this on the hot
water side the same way. Now I flush the toilet until only air is
present. Don't forget the shower(s)! This process should evacute
water in the plumbing so freeze up is avoided. I leave all faucets
open in case there is water remaining it has a place to expand.
Now I return to the water pump and remove the screen bowl and make
sure
no water remains. It is important to ensure you really tighten the
bowl when you re-install it or you'll have leakage in the spring. You
should return the HWT by-pass valve to its normal position at this
time
so as not to foget it. If you don't, you won't be able to fill the HWT
and could damage it if you turn on heater. MUST HAVE WATER IN TANK
before you turn on heater.
Now I put vaseline on the toilet trap door to prevent it from sticking
shut. I also, open the grey water vave to ensure all water is drained
then I only close it half way. Do this on the black water valve also.
In the spring it is easier to push a stuck valve than to pull a stuck
valve. Pour about a cup of ant-freeze into each sink and shower drain.
You're done.
One last thing I contact my Insurance Agent to suspend my laibility
durng the storage months. Also, suspend Sirius radio programing.
Works for us,
