I am hooked up to city water yet no water will come out of any of the faucets in inside the RV. I have checked and the water is coming out of the city water spigot. I have a 2017 Thor Chateau and can not find the low point drain; I’m not sure if finding that is even relative to my issue. Two questions: 1-where is the low point drain located on a 2017 Chateau and 2- What else might be the reason for my issue? I appreciate any help.
