First time trying the blow out method. The one thing that I typically dont see is what do folks do with the freshwater pump?
The one thing I read was to fully drain the freshwater tank. Then turn the pump on and let it run until no water comes out and then continue for another 15 20 seconds to continue to clear out any remaining water in the pump. Is that sufficient?
I've used no pink stuff in any lines, just air. I did put the pink stuff in the traps and in the toilet bowl.
Also my GD 2400BH has a black tank water inlet for a spray bar to clean inside of the black tank. Is it necessary to blow the line for that considering there are no valves and it's not pressurized? I already did it but just curious if its needed.

I used to only blow out the lines but I only did that for one year, I had to replace a lot of water lines that froze and burst. Now I blow out the lines and use rv freeze in the lines. they hake a rv anti freeze valve and you can place it on the pump intake and it only takes less then a gallon of rv anti freeze to winterize your RV. with the valve left in place there is an on/off built in valve, sure makes winterizing a lot easier.

Don't rely on just blowing out the lines. All the times I have winterized I blow the lines then put in anit freeze and there is a lot of clear water that comes out before the pink stuff does. Your trailer, your choice but be prepared to fix freeze damage.

^^^^^Yes, it is needed, unless you have never used it. Water will stay in that line, and may damage the backflow preventer.

This is why I don't blow out the lines. Too many questions on if you got it all out! Pull the low point drains and run the RV antifreeze through it.

Blowing will not remove all the water. Yes you must blow ALL lines. No need to blow if your gonna add anti freeze. Wast of time. If you only blow, how do you get water out of the pump. I can put anti freeze in my rig in 15 min by myself. How do you get water out of the icemaker, Dish washer, washing machine if you have these?
Antifreeze is easier and more effective. Don't put it in your fresh water tank.

Been blowing my water lines with air for 15 years, if you check all your faucets to be sure there is no water, just air coming out, there will be no problems with freezing water. Sure, there might be a small amount of residual water in the lines somewhere, but not enough to cause damage to lines. The one gallon of rv antifreeze goes in the traps, and the rest in the holding tanks. No problems yet. Just take your time, don't rush thru it. But different strokes for different folkes.

I have been blowing my lines for 20+ years with no problems - just take your time and do it right. Focus on making sure things like your toilet valve are clear of water. When I used the pink stuff I never bothered to blow the line first - that makes little sense to me and seems like massive overkill.
