What Is an RV Water Pump?
The RV water pump is a crucial component in your recreational vehicle (RV) plumbing system.
A well-functioning RV water pump ensures you have running water even when you’re not connected to a city water supply. Regular maintenance and checks are essential for a smooth RV experience!

It serves as the delivery service between your fresh water tank and the fixtures (faucets, toilet, and shower) inside your RV. Without a working water pump, your RV’s plumbing system would be non-functional. Pumps come in various configurations to suit different RV sizes and needs. Large RVs need more powerful pumps than smaller RVs.
How does an RV water pump work?
- An RV water pump is a motorized diaphragm pump that draws water from the freshwater tank and sends it to the fixtures.
- It operates at 12 volts, directly wired into the RV’s 12-volt system.
- When you open a fixture (like a faucet), the water pressure in the lines drops.
- The pump detects this low pressure and powers on to maintain consistent pressure.
- Once the desired pressure is reached, it shuts off until another fixture is opened.
Types of RV Water Pumps:
- Constant Speed Pumps:
- These are the most common type.
- They deliver water at a consistent speed regardless of application.
- Inexpensive but tend to have a shorter lifespan due to prolonged running.
- Variable Speed Pumps:
- Raise or lower motor RPM to maintain pressure based on demand.
- More efficient, quieter, and longer-lasting.
- Consumes less energy.
High Volume Pumps:
- Used in large applications (e.g., motor homes, bus homes).
Remember to choose a water pump that suits your specific needs and installation requirements. Happy RVing!
