Water System Diagram

The water system in a Keystone RV is designed to provide fresh water for drinking, cooking, and bathing. The system includes a water pump, water tank, water heater, and various pipes and fittings. The water pump draws water from the water tank and pumps it through the water heater and into the faucets and shower.
The water heater heats the water to a comfortable temperature for showering and bathing. The water heater is typically powered by propane or electricity.
The water system is a closed system, meaning that the water is not exposed to the outside environment. This helps to keep the water clean and free of contaminants.
Components of the Water System
- Water pump
- Water tank
- Water heater
- Pipes
- Fittings
Flow of Water Through the System
The water pump draws water from the water tank and pumps it through the water heater. The water heater heats the water to a comfortable temperature for showering and bathing. The water then flows through the pipes and into the faucets and shower.
Plumbing Fixtures and Appliances

Plumbing fixtures and appliances are essential components of an RV's plumbing system. They provide access to water for various purposes and contribute to the overall functionality and comfort of the RV.
The following table lists the plumbing fixtures and appliances typically found in an RV, along with their locations and relevant specifications:
| Fixture/Appliance | Location | Specifications |
|---|---|---|
| Kitchen Sink | Kitchen Area | Single or double basin, with hot and cold water faucets |
| Bathroom Sink | Bathroom | Single basin, with hot and cold water faucets |
| Shower | Bathroom | Enclosed area with a showerhead and hot and cold water controls |
| Toilet | Bathroom | Flushing toilet with a waste tank |
| Water Heater | Utility Area | Propane or electric-powered device that heats water for the fixtures and appliances |
| Water Pump | Utility Area | Electric or manual pump that draws water from the freshwater tank to the fixtures and appliances |
| Freshwater Tank | Undercarriage | Tank that stores clean water for use in the fixtures and appliances |
| Wastewater Tank | Undercarriage | Tank that collects wastewater from the fixtures and appliances |
| Water Filter | Utility Area or Kitchen | Device that removes impurities from the water supply |
Waste System Diagram

The waste system in a Keystone RV is designed to collect and dispose of wastewater from the sinks, toilets, and showers. The system consists of a series of pipes, valves, and tanks that work together to move wastewater from the fixtures to a holding tank. The holding tank is then emptied at a designated RV dump station.
The waste system diagram below shows the location and connections of all the components in the system. The diagram is divided into two sections: the black water system and the gray water system. The black water system collects wastewater from the toilets, while the gray water system collects wastewater from the sinks and showers.
Components of the Waste System
- Black Water Tank: The black water tank is a holding tank that stores wastewater from the toilets. The tank is typically located under the RV, and it is connected to the toilets by a series of pipes.
- Gray Water Tank: The gray water tank is a holding tank that stores wastewater from the sinks and showers. The tank is typically located under the RV, and it is connected to the sinks and showers by a series of pipes.
- Waste Valve: The waste valve is a valve that controls the flow of wastewater from the holding tanks. The valve is typically located on the outside of the RV, and it is used to empty the holding tanks at a dump station.
- Vents: The vents are pipes that allow air to enter the waste system. The vents help to prevent the system from becoming clogged, and they also help to reduce odors.
Electrical System Diagram
The electrical system is the backbone of any RV, providing power to all of the appliances and systems that make it comfortable and convenient to live in. A well-designed electrical system will ensure that all of your appliances and systems operate safely and efficiently, and it will also protect you from electrical hazards.
The electrical system in an RV is typically divided into two parts: the 12-volt DC system and the 120-volt AC system. The 12-volt DC system powers the RV's lights, water pump, furnace, and other small appliances. The 120-volt AC system powers the RV's air conditioner, refrigerator, microwave, and other larger appliances.
The 12-volt DC system is typically powered by a battery, while the 120-volt AC system is typically powered by a generator or by an electrical hookup at a campground. The battery is used to store electricity for use when the RV is not connected to an electrical hookup.
The electrical system in an RV is a complex system, but it is important to understand how it works in order to ensure that it is operating safely and efficiently. The following diagram shows a typical RV electrical system.
Components of an RV Electrical System
- Battery
- Converter
- Inverter
- Circuit breaker panel
- Electrical outlets
- Appliances
The battery is the heart of the RV electrical system. It stores electricity for use when the RV is not connected to an electrical hookup. The battery is typically a deep-cycle battery, which is designed to provide a steady flow of power over a long period of time.
The converter is a device that converts 120-volt AC power to 12-volt DC power. The converter is used to charge the battery and to power the RV's 12-volt DC appliances.
The inverter is a device that converts 12-volt DC power to 120-volt AC power. The inverter is used to power the RV's 120-volt AC appliances.
The circuit breaker panel is a device that protects the RV's electrical system from overloads. The circuit breaker panel contains a number of circuit breakers, each of which is designed to protect a specific circuit in the RV's electrical system.
The electrical outlets in an RV are used to plug in appliances and other devices. The electrical outlets are typically located throughout the RV, so that you can easily access power wherever you need it.
The appliances in an RV are powered by the RV's electrical system. The appliances in an RV typically include a refrigerator, a microwave, a stove, and an air conditioner.
Flow of Electricity in an RV Electrical System
The electricity in an RV electrical system flows from the battery to the converter to the inverter to the circuit breaker panel to the electrical outlets to the appliances.
When the RV is connected to an electrical hookup, the electricity flows from the electrical hookup to the converter to the battery to the inverter to the circuit breaker panel to the electrical outlets to the appliances.
When the RV is not connected to an electrical hookup, the electricity flows from the battery to the converter to the inverter to the circuit breaker panel to the electrical outlets to the appliances.
