Rv hot water tank diagram. Water exits the trap and runs through a flexible 3 4 hose to the grey water tank underneath the van. Unfortunately the system is not real accurate. As the water warms it rises to the top of the tank. As you use the hot water which exits from the top of the tank the water pump senses a loss of pressure in the system and pumps more cold water in through the tube into the bottom of the hot water tank.
Your hose will screw on to the city water port but the fresh water fill aka. As water is pushed through the water lines some of that water is forced into the water heater s tank. The three main holding tanks fresh water gray and black sewer all will have a similar system to tell the rv er how much fluid is in the tanks. You only get a short supply of hot water which quickly turns lukewarm and then cold.
Rv water heaters are powered by propane electricity or both. As the picture to the left shows it usually will have 3 or 4 sensors in the side of the tank. If you look at the rv plumbing diagram it can be placed anywhere on the hot orange or cold blue lines. Gravity fill port will usually be a larger opening that the hose just slides into.
