Can anyone tell me....
Firstly I have isolated the hot water tank.
As I do not have a suction hose fitted for directly adding RV antifreeze from inside the RV at the water pump, I am going to add it thru the fresh water tank fill hole from the outside so....how many gallons will my travel trailer need added into the fresh water tank...before my pump can pull it thru?
This question is probably best answered by persons who prepare their RV for winter the same way as I plan to.
I do not have the facility to blow high pressure air thru the lines.
The RV is stored away from my residence.
