What is an RV Water Pump?
An RV water pump is a device designed to provide a steady flow of water in recreational vehicles (RVs) or motorhomes. It is typically used to draw water from a fresh water tank and distribute it throughout the RV’s plumbing system, including faucets, showers, toilets, and other water fixtures.
The water pump operates using an electric motor that creates suction to draw water from the tank and pressurize it. When a water fixture is turned on, the pump senses the drop in pressure and automatically activates to maintain a constant water flow. Once the fixture is turned off, the pump shuts off to conserve power and prevent unnecessary cycling.
RV water pumps are compact in size and are usually installed in a convenient location within the RV, such as near the water tank or behind a panel. They are powered by the RV’s electrical system, typically running on 12-volt DC power, although some larger RVs may have pumps running on 24-volt systems.
Having a reliable water pump is essential for RV owners to ensure a consistent water supply for various activities, such as cooking, cleaning, and personal hygiene, while traveling or camping in remote locations where a direct water hookup may not be available.
How Does an RV Water Pump Work?
An RV water pump gets your water system flowing with a simple yet powerful design. It uses 3 to 5 flexible diaphragm chambers and an electric motor to generate water pressure. Although basic, this setup allows an RV water pump to work with maximum functionality.
The pumps run on a 12-volt system that maintains a pressure in the water lines. When you turn on a water fixture, like the faucet or shower valve, that built-in pressure gets released. It triggers the pump into high gear to rapidly push out water. It will keep doing this until it reestablishes the correct pressure, which is when you turn off the water.
Shut off the water when you’re done and the pump automatically cuts out. At that point, the pressure in the pipes naturally stays buoyant until the next time you need a splash. This on-demand design is efficient and keeps things simple.
Technically, an RV water pump works by utilizing a combination of suction and pressure to draw water from a fresh water tank and distribute it throughout the RV’s plumbing system. Here’s a step-by-step overview of how it typically operates:
- Power supply: The RV water pump is connected to the RV’s electrical system and usually runs on 12-volt DC power. When the power is turned on, the pump is ready to function.
- Suction and priming: The pump creates suction by using an impeller, which is a rotating component with vanes. As the impeller spins, it creates a low-pressure area, causing water to be drawn into the pump from the fresh water tank through an inlet or intake pipe. This process is known as priming the pump.
- Water flow: Once the pump has successfully primed and water is drawn into the system, it is then pushed through the pump and into the RV’s plumbing network. The pump pressurizes the water to ensure a consistent flow and sufficient pressure at the water fixtures.
- Pressure switch: When a water fixture, such as a faucet or shower, is opened, it creates a drop in pressure in the plumbing system. This drop is detected by a pressure switch or sensor connected to the pump.
- Pump activation: When the pressure switch senses the drop in pressure, it triggers the pump to activate. The pump’s electric motor starts running, and the impeller generates pressure to push the water out of the pump and towards the open water fixture.
- Water usage: As water flows from the pump, it travels through the plumbing system, reaching the desired water fixtures in the RV, such as sinks, showers, toilets, or outdoor faucets. Users can control the flow by adjusting the fixture’s valve.
- Pump deactivation: Once the water fixture is turned off, the pressure in the plumbing system increases. The pressure switch detects this increase and signals the pump to shut off. This prevents unnecessary cycling and conserves power.
It’s worth noting that some RV water pumps have additional features, such as built-in filters to prevent debris from entering the system or automatic shut-off mechanisms to protect the pump from damage if the water supply runs dry.
