No hot water during a freeze

Frozen water line or something lodged loose by the cold and blocking water line.

I would assume it is the cold water pipe that feeds the water heater. This will run from the pump or inlet to the water heater. If you are using the inlet, try the pump. If you are using the pump try the inlet. You need to somehow defrost this connection. Skirting around the base of the RV might help. Use the furnace instead of space heaters. And turn the heat up a bit. Or head south.

What is the forecast high and low for the next few days?

I was thinking he was south but reminded me of the kerosene heater we had in Miami a few years ago.

Hot water will freeze before cold water.

That is a myth

There are several possible answers #1 with an ice cube is the water line to or from the heater is frozen. Heater is likely OK but a line is froze.

Open cabinet and drawers near water lines. Remove the back side (indoor) acess panel to the water heater and let it thaw.


Alternate posibilities are coinvidenve and we will skip them for now.

Well water that has need heated and has cooled will freeze quicker than cold.
Where are your low point drains? Mine hang down about 3” below the floor and a I protect them with an outdoor faucet cap.
