Whenever the cold or hot water taps in my caravan are turned on , water leaks out onto the burner of the carver heater burner on the outside of the van (can be seen when the external cover is removed). No leak to the inside of the van. I'm guessing that it wasn't fully drained last wineter and ice has burst something. Can they usually be repaired or is it a case of replacing the whole heater?
