There may be a solenoid that opens like on a washing machine to divert water to the fresh water tank.

And it appears there is

Hi Michael

'hwh'? Abbreviations are so hard to deal with here on Fixya. There is no extra charge for using more letters. 'hot water heater', but it is a guess. I read this part 10 times

hook up wires in back of what he to
Still no clue on that one.

The only part I do know is that you have a 2012 R-Vision Silver Creek 30 QBH.

There are no wiring diagrams for it.

The water connection is typically on the driver's side outside wall. You most likely have a valve that switches between "Fill" (a ~60 gal. water tank) and "City pressure" that allows the water pump to be turned off. If the water fill isn't visible on the sidewall, check in the wet bay for the connection.

Go to an RV parts store for a winterizing bypass kit for the water heater. Use POTABLE RV antifreeze and follow the instructions on the bottle. Drain all the water out of the water tank. Install the bypass kit on the water heater if it doesn't already have one. Put the water heater in the bypass mode. Add the antifreeze to the water tank. Open every water faucet including the shower head one at a time until antifreeze is present. Do this for hot and cold on every faucet. Once that is done, turn off the water pump and open all the faucets. That's all there is to it. Rember... DO NOT use automotive antifreeze. It will kill you.

De winterizing is easy. They use a pink antifreeze which is food grade. Make surer the water heater is not by-passed. This is sometimes done using furnished bypass valves so that less antifreeze is needed. You can flip the water heater pressure release after connecting to city water. Water will come out if it is full. Do NOT turn on the water heater until you are certain the tank is full of water so as not to burn out the element. (This is true every time you set up) Run all faucets until you no longer see pink and you are de winterized.

Any more they could be in numerous places but look for a brown cover/door usually. Look low, such as under fridge, under bench seats, as well as on wall in bathroom, bedrooms etc.

Connect the trailer to the city water supply, turn on the water and open each faucet until clean clear water is present. Don't forget the toilet and outside shower if equipped. Next reinstall the anode rod (suburban) or drain plug (atwood) into the water heater. Go to the back side of the water heater and close the valve on the pipe that connects the cold (bottom line into water heater) and hot (upper line out of the water heater) and then open the bottom cold water line valve and, if equipped, the upper hot water valve. This will fill the water heater. Open the hot water valve at the kitchen faucet. When the water flow is steady the water heater is full and ready for use. If the unit is equipped with a water filer, after all is flushed out, turn the water off and remove the filter housing. Install a new filter and re-secure the housing and turn the water back on. If you are using the fresh water pump, it is possible that the winterizing valve for the pump was left open. If so, close that valve which will divert the pump back to drawing from the tank.
