Draining water lines
Hello, I'm getting ready to winterize my 2017 Winnebago Minnie Winnie 27Q MH. Reading the operators guide it states there should be Two (2) water system drain valves and the water heater bypass valve...

Is blowing out the system really that effective?
Depends on your RV. My 1990 Winnebago Warrior has 4 drain valves. 2 under the bed with the water tank and pump, and 2 under the bathroom sink. Since the valves are the low point in the vehicle, when you open them (and open all the faucets prevent any vacuum preventing draining) all the water goes out the drains. I bought one of those blow-out fittings thinking it was all necessary and when I hooked it up only air went through the system - there was no water left in the system to blow out.
So, I don't bother trying to blow anything out anymore. Pull all 4 drains and open the faucets and everything drains out on its own via gravity.
