HUMMMMM sounds like another one of Lon's lap dogs. The 30% Propylene
Glycol provides a -50 protection and this is acquired by not
diluting it any further. 50% Propylene Glycol is not the standard
pink stuff and I commented that an assumption is that you could
dilute the 50%, I did not indicate any thing about diluting the 30%
You also made my point about freezing protection. If you flush the
30% solution through a water system how do you know that all areas
has been exchanged by the pink stuff and not just diluted some in
some parts. I still say get rid of the water first by blowing it out.
Naw, Lon does his thing and I do mine. Just once in awhile someone
comes along who we both agree on, good or bad. You're him, sorry.
Sorry I misunderstood what you posted. But where do you buy 50% RV
Propylene Glycol? Why would you buy it. If you live somewhere where
you need to go to below -50 your RV should be an igloo on a sled, like
I said before. You shouldn't assume, especially on this newsgroup :)
I believe I or someone else has already explained to you how to flush
out a system using antifreeze. But what the heck, maybe it will stick
this time. When you flush (pump) antifreeze or almost any other
liquid through a pipe guess what, if there is water in that pipe it is
going to be *pushed* out in front of the flowing liquid. It may
however mix a little with the leading flow of antifreeze. That's why
you run the faucets until the antifreeze comes out the color it is
inside the bottle so you make sure you get all the water in that pipe
out. If you don't drain the antifreeze it's going to sit there
undiluted throughout the piping. Even if you drain it there is going
to be undiluted antifreeze in any low spots. Could there possibly be
some water that somehow didn't get expelled by the antifreeze? Maybe,
but it's going to be so small an amount it isn't going to matter, it's
going to be diluted with antifreeze anyway, unless you didn't flush
the system right and then it doesn't matter how you do it. The big
point is to get antifreeze into any low spots or spots where water may
sit. You want to push that water out and leave antifreeze in it's
place. Like in the pump for example.
You didn't say get rid of the water first by blowing it out. You
said blow out the lines to winterize. That is a big difference. The
original post was from someone who asked if they winterized by blowing
the lines out do they have to use antifreeze. You said you used air
and described how you did it. Lon came back with his reply about
using air isn't a good idea all over the country. Then the whole
thread took off, you saying that air was the original way etc. etc.
etc. Later you changed your mind and said you blew out the lines then
used antifreeze if you do not intend to use the rig for awhile. But
that was 3 or 4 days later after someone else had told how they used
air to blow out the lines.
You are all over the map on this. All I am saying is you should not
recommend to ALL people to use air to winterize. Especially if they
live in the north. Antifreeze is simpler, easier and just as quick
and more thorough.
Did you and dog get out yet? I'm gettin ready and hope to be gone
for the rest of the summer and fall. So get your jabs in while you
