Water problem

[Shane Fleeman]

Hello, I am new to this forum and hoping someone can help. We have a 2022 Cameo fifth wheel that we keep in Georgia. Like most, we are experiencing below freezing temperatures. I have a heated hose coming into the fifth wheel and confirmed water is flowing in and the water pump seems to be working. When I turn the faucet on, hot water flows through but when I move the knob to the cold side, the water stops flowing. Any thoughts on what’s causing this?

Somewhere, the cold line has frozen. I have PEX with brass fittings. They freeze on one side of a "T" sometimes, yet the other side stays thawed.

Ok. I was afraid that was the case. Thanks for the reply
