Winterizing the RV
Howdy: My wife Virginia & I just purchased a 2004, 26.5', mid-bath, Lazy Daze RV. I've reviewed the factory manual's section on winterizing, and am not especially confident about doing this successfully. (The procedures are more complicated than I would have thought). (We're rookies). We live in upstate N.Y. and it gets pretty chilly here in January. Any advice on how-to would be most appreciated. Specifically: purging H2O from the system with compressed air. (I have a compressor). What I'd like to do is a 'dry' run, i.e. go through all the steps, purge all the H20, and then refill the system, since we'd like to do a shake-down trip before leaving for Alaska next May. Any advice would be most welcome.

Hi Davidmo. Welcome to the forum and congrats on your “new” Lazy Daze!

I’ve performed the winterizing (compressed air) process outlined in the manual and found it to pretty accurate. My MB is a bit newer but I suspect the process is similar.  I think it’s one of those things you just have to do a few times to get comfortable with.  In the MB, one of the hardest parts is getting access to the water pump as the converter makes things quite tight.  If you have specific questions or concerns, let us know.

Do you have a hose like this one to connect to your water line (disconnect from the exit side of pump) to your air hose?

More costly, but reassuring, I filled the RV water system with antifreeze.  I lived in northern Va when I had the LD.  But we would get temps into the single digits from time to time. 
 I made a little device that sucked antifreeze
 out of the bottle just before the filter that is between the fresh water tank and pump.  The pic of the filter was taken after pumping the antifreeze.  

I could not fit all the pictures into one entry.  So at least the pic of the antifreeze bottle and device in action will be in the next post.

When hooking up the air hose to the water line it is handy to have a shorty wrench.  I got mine from Amazon but there are better places to buy tools.  Before I said water pump.  That was wrong!  You hook up to the water line on the out side of the water pump.

Picture of the air hose hose again too.

Hi David and welcome!

 I agree with John on going the anti freeze route. I also have a similar set up to fill my lines, but mine is located after the filter and before the pump, I just empty my filter each year. I also have a bypass on the water heater so I save about six gallons of antifreeze. I was warned of potential problems with going the compressed air route so I never attempted trying it.

Once you do this method a couple of times you can do it quickly. We usually return home from annual snowbird travels before the danger of freezing has passed, but I can usually do this in less than an hour tops.

Best of luck,
Ron
