chevyman: thanks for the reply. Found the bad check valve and removed it and did obtain water to front area of trailer. The unit is a rear kitchen and the hot water heater is towards the rear of the trailer. We now do not have any water flowing to the rear of the trailer. So kitchen sink and hot water is minus water. I do not see where there might be another check valve. It could still be frozen line in the underbelly of the trailer were hoping but not sure. Any ideas on a fix.
