Yes, many do blow out lines and do not use RV antifreeze in the water lines, myself included. I have not had a problem yet with destroying things because of freezing. But, make sure you get EVERYTHING blown out.
Start emptying your fresh tank and then run your water pump until there is no more water being forced out from the pump.
Then, hook up your air compressor and set the output to about 45 psi but also use an air restrictor on the City water inlet.
I generally do the water heater first with air. When down to the last bits of water, I put my hand over the WH outlet to build up air pressure and remove the hand, letting water continue to get hurled out. I do this many time to get as much out as possible. Then turn your WH bypass valve.
Next, I start with the closest connection and work to the furthest. Do not forget the following:
Toilet
Sinks hot/cold
Outside shower hot/cold
Shower hot/cold
Black tank flush kit
Any other water items YOU have
Low point drains
I will run through all of those and then do another run through. Usually pretty quick.
Drain both gray and black tanks.
Lastly, pour some RV antifreeze in all of the sink P-Traps and in the toilet. I usually use about 1 gallon for this so as to get some pink in the tanks for any left over water in there.
