what size compressor to winterize

Great idea, pressurize the hot water tank.
Wait till next year.

You don't need anything powerful to winterize - I use a simple 12 volt compressor (which isn't very powerful) for 25 yrs. I don't see the logic of putting in pink stuff if you blow your lines .. overkill in my opinion.

That is your opinion and I can tell you for a fact that water will settle in the lines in low spots and during a hard freeze you can break lines. I know, I have had it happen.

Pink stuff pushes the water out and what doesn't go out mixes with it to lower the freeze point where it will not freeze. There is just no way with air to get all of the water out

Precisely! That's why I always follow up with the pink stuff after blowing out almost all the water. The little extra time and a couple of bucks more it takes is well worth it to me.

To each their own. Whatever suits each individual. :@

I'm fortunate to have 3 low drain lines and one on the water heater. After I do that I use my pancake compressor and get the rest. The anti freeze the traps. Takes less time than to telll about it.

For many years all I did was blow out. I learned early on that higher is not better. I found that 15-20 PSI was ideal. Any conpressor capable of that will work. I use my 135PSI pancake compressor andmit does just fine. Since adding a washer I now first blow out, then pump antifreeze so the washer is protected.

I have used air,but just less fooling around using the pink anti-freeze,2 gal and 10 minutes your all good.

your unit is plenty big I blow back the lines ,water flows better down hill . I take the strainer of the faucet and use a dish towel around the hose and blow it in the faucet. open your low point drains. then put the pink stuff in.

I do the same as MFL. There is always a little bit if residual water left somewhere in the lines after blowing them out with compressed air. I always pump the pink RV anti-freeze through the lines as insurance. ;)

Murphy's law, if anything is going to freeze and crack, it is usually a fitting in the worst location to get at and repair. :(
