Why replace it? Just blow it out with air. The air will not expand when it freezes.

Living in California I did have about 20 morning freezes a year and never used antifreeze.
Good shop vac does the job easy.

This was my first RV, a 1969 Excel TT.

The first winter I installed the water heater bypass and pumped the pink stuff throughout the entire system and didn't have a single issue.

That following spring it seemed like it took forever to get rid of the smell and taste of it. I never used it again.

I started "flushing" the system with compressed air and just pour the pink stuff into the P-traps.

It gets down close to -20° here and I have yet to have a problem.

Now come spring time its fill the FW tank and I'm ready to go.

I would struggle leaving it in there for any extended period of time.

X3.
But dry winterizing requires some working knowledge where filling everything full of the pink drink is generally idiot proof.

Oh and for tanks and non potable stuff, windshield washer fluid works good and less expensive.

Are you guys using an air compressor to blow out the lines? What about oil in the air?

I use an oil-less compressor.

I like the shop vacuum idea to pull the fluid out.
I have never actually winterized as mine is stored in warm So CA.

I am not sure what the point of putting pink into a drained fresh tank would be, at any time let alone for a few years. In any case to winterize I blow out the lines, then flow the pink through, then blow out again. Makes is so much easier to get the pink taste/smell out of the lines in the spring because it hasn't been eating into the lines all winter.


First. If you blow it out. No need for pink. second. When I bought my camper they ran water thru the pump. I needed to get that out, Blowing won't blow out the pump. So I needed to get pink to run thru the pump. As I can't get to the back of my pump to hook a hose to pump directly out of a jug. I had to put enough into the fresh tank for it to pick up. And since I don't use my fresh tank. I left it in there. now I just blow it out because there is no water in the pump ..
Hope that explains it all to you.

Compressor. But watch the psi, RV lines only rated to 45 psi. You can get an adapter with quick disconnect to compressor and std hose fitting on opposite end made for this purpose.
