we were camping this weekend, Friday night after setup i ran some water in the bathroom sink on the hot water side and there was air in the lines, (probably cause last week i cut the water line and installed a t, and valves and a line to draw antifreeze through to winterize it in a couple of weeks) so i let the air and water run for a period of time, and all at once the cold and hot both quit running almost entirely. All the rest of the lines worked fine all weekend? Any advice?
