Yeppers. I worry about water residing in the low areas and elbows when blowing lines. Air can blow past those areas in the void at the top of the line, still leaving water in the lines. Case in point, just when I think I have a line blown, it will still spurt water when I do it "1 more time". When is enough "1 more times" sufficient ??
I blow the lines, then fill them with antifreeze. Because the antifreeze is not diluted with the existing water (except for the low areas), the antifreeze is close to 100%, the way it is intended to be used. I very well could just leave the antifreeze in the lines for winter.....not a problem. But by blowing the near 100% antifreeze out, I end up running that 100% stuff to the drains, and to the waste tanks....which solves winterizing those 2 items.......I have already completely drained my waste tanks, so there should be nothing but a little 100% antifreeze in those. I will still pull the waste tank valves (into a bucket for proper disposal) to double check that nothing is dammed up behind those.
Blowing the lines now performs another function.....I don't have to blow them next spring before my yearly sanitization (sp?) of the fresh water tank and lines.
