We've been in a cold snap for about a week with daily highs below -20C. The water is not running to one toilet that is near an exterior wall. To ensure it wasn't something in the tank, I detached the flexible hose from the tank that runs to the wall and no water is coming through there. Is likely a frozen pipe? What do I do now?
Update: We turned up the heat in the bathroom and the room below the bathroom and used a heat gun on the exposed part of the pipe extending from the wall. Eventually it just started flowing again. We'll keep an eye out for drips before cutting open the wall.
