Winterize 8329SS

We recently purchased a Rockwood 8329SS. We were hoping to use it before Christmas but doesn't seem like it will happen. The TT is currently in storage. Is there a way to blow out the lines if I don't have an electric hookup? Sorry if this is a dumb question. I think once I have the lines blown out I can figure out the antifreeze part.
Thanks

You don't need electric hook up. You also do not need to blow out the lines. Especially if your gonna use anti freeze.

open a hot and a cold faucet and drain your low point drains. Close drains. Close the faucets.

You will need a pump by pass kit installed between your pump and your FW tank. You may already have one. It's a flitting with a valve and a 2' hose. You put the hose into the antifreeze jug and use the pump to pump antifreeze throughout the trailer. Open one faucet at a time until the pink stuff flows. Don't forget the toilet and outside shower. Open low point drains until the pink stuff flows. Remove the City water intake screen and push the check valve in with a screwdriver. Stand out of the way. When the pink flows you will have put some in the p-traps. Put some in the toilet. Don't forget the showers. Sounds like a LOT but Takes me only about 15 min and 2 gals of antifreeze.

if you have an air tank or air in a compressor you don't need power. I made a fitting that screws into garden hose threads and goes to the quick disconnect on my air hose

Without a compressor or electric your only way to blow out the lines are with an air tank, a portable compressor (with a tank) that has already been pumped up to full capacity, a bicycle/air mattress pump, or using your mouth/blowing on a garden hose! (yes it can be done! LOL!)

As mentioned though, if you are going to pump antifreeze into the system, blowing out is not a REQUIREMENT but rather a way to save a bit of antifreeze. Using the low point drains to drain the plumbing, as cavie mentioned, is perfectly fine.

When you blow out a system with air and then ingest antifreeze into the plumbing you are fairly certain when the pink begins to flow it is pure antifreeze.

If you don't blow out the system first, you 'could' get water (left behind from simply draining via the low point drains) or a mixture of water and antifreeze coming out the faucets before it turns pure antifreeze.

With the price of antifreeze being just a few dollars a gallon, it really doesn't matter much in the long run as long as you have enough antifreeze and then run it long enough to be sure no water remains in the plumbing.
