what size compressor to winterize

[NEnative]

good morning everyone, I have a 38 foot prime time crusader and I have a pancake compressor. What size compressor do I need to winterize a 5ver this large if I were to blow out the lines and pour antifreeze into the traps?

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.

I first empty the hot water tank. Then pressurize the system using the hot water tank as the compressed air storage place. Then open each faucet sequentially until the water stops flowing. When all completed, pour RV antifreeze into the traps. That's it. Not a big deal.

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. 😞

Most pancake compressors will work. It just needs to be able to push a continuous 30-40 psi through the lines. Don't know your Winter low temps, but may be best to put anti-freeze in the lines also, rather than just the traps.

I blow, and use pink, but that's just me, many do not.
