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 ...

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.
Correct!
It is the same thing as opening a water bottle and dumping out a small amount of water BEFORE you put the bottle in a freezer.
You give the water a place to expand and nothing will be damaged.
However, sadly a lot of folks on this forum do not have a grip on the science behind the theory and are so afraid of damaged lines they re adamant that pink stuff must be pumped through..
Each to his own, if the pink stuff makes you sleep better then use it.
If blowing the lines clear until a light mist comes out then opening up the low point drains and leaving the faucet valves open all winter doesn't cause you to lose sleep then do it that way.
As far as water pump goes, mine sits slightly above all of the water lines so any water left in the lines will drain away from the pump.. Have not had an issue as long as I have owned this TT (15 yrs).
May not be that way on yours so inspect how your pump is mounted and if it is lower than the rest of the lines. If lower then either use the pink stuff OR simply OPEN the lines at the water pump to allow residual water drain off..
The main takeaway is there must be breathing space in the lines at all times when not using pink stuff.
