if it hasn't happened to you then great- I personally blow out my lines and then add the pink stuff- just cuz = sticks are almost always free and I don't have to worry about
A co- worker of mine did the same thing and froze his foot valve on the toilet-- major pain to replace--
Also just so you know there is also a oneway valve on the city water fill that you should stick a toothpick in to hold the valve open- A camper manufacture told me this- again- toothpicks are almost always free--
