We were in Elkhart having the mis-sized bolts replaced between the frame and suspension (see http://www.irv2.com/forums/f104/poss...05s-66414.html
) and we asked them to look at our problem of low cold water pressure. It didn't matter what the city water pressure was, or if we used the pump, the cold water pressure in the kitchen, bathroom and toilet was awful. And, It took about 40 seconds to get a decent amount of water in the toilet. We had no idea how the tech could track the problem. The tech later came into the waiting room with a coffee cup that had about 1/4" of crispy little white things that he had extracted from the lines leading to the sinks and toilet. They appeared to be calcification. Now, these pieces are too big to get through the screen at the water inlet, so they must form as the minerals from the water build up. The sink pressures are now much better and the toilet fills in about five seconds! Just a heads up in case others are experiencing this problem.
