I'm thinking of new plumbing for my house when I remodel. I live in the NE and we have hard water. When I leave for the winter I pump RV anti freeze into the copper lines. Should I use the new flexible hose when I replumb? Is there a way to get around using the RV antifreeze, such as hooking up an air compressor to the line and blowing the water out. Is it possible that water would still be trapped in the lines somewhere or that I would damage the lines by blowing them out with air??

Any help on this subject would be appreciated, thanks.

Using compressed air to blow out the lines is very common practice any place with "summer" homes.

It is also they way that sprinkler systems are winterized.

You will still want to pour some RV antifreeze in traps.

And when you replumb you if you watch you runs and design them so that there are drains (either a faucet or a valve added just for that purpose) are at the lowes point you can get by with out blowing down the lines.

I have heard that PEX is tolerant of freezing with water in it. But I have never used it.
