Essential RV Knowledge: Does the Water Pump Really Stay On?

When you embark on a journey in your RV, access to running water is paramount. The water pump plays a crucial role in delivering water throughout your RV. However, a common question arises: does the RV water pump stay on continuously or does it have an automatic shut-off mechanism? This blog post delves into the intricacies of RV water pumps, exploring their functionality and addressing the burning question of whether they remain operational indefinitely.

Understanding RV Water Pumps

RV water pumps are the heart of the water system, responsible for drawing water from the fresh water tank and distributing it to various fixtures and appliances. They come in two primary types:

• Demand Pumps: These pumps activate only when a faucet or appliance demands water.
• Constant Pressure Pumps: These pumps maintain a constant water pressure throughout the system, even when no water is being used.

Does RV Water Pump Stay On?

The answer to this question depends on the type of pump installed in your RV.

Demand Pumps

Demand pumps are designed to turn on only when a faucet or appliance is turned on. Once the water flow stops, the pump automatically shuts off. This helps conserve power and reduces wear and tear on the pump.

Constant Pressure Pumps

Constant pressure pumps, on the other hand, are designed to maintain a constant water pressure in the system. They continuously run to maintain the desired pressure, even when no water is being used. This ensures that you have consistent water pressure at all times.

Advantages and Disadvantages of Each Type

Demand Pumps:

• Advantages: Conserve power, reduce pump wear and tear
• Disadvantages: May cause fluctuations in water pressure, can be noisy when turning on

Constant Pressure Pumps:

• Advantages: Consistent water pressure, quieter operation
• Disadvantages: Consumes more power, can be more expensive

When to Use Each Type of Pump

The type of water pump you choose depends on your specific needs and preferences.

• Demand pumps: Ideal for RVs with limited power or where conserving water is a priority.
• Constant pressure pumps: Recommended for RVs where consistent water pressure is important, such as for showering or using appliances.

Troubleshooting a Continuously Running Water Pump

If your RV water pump is running continuously, it could indicate an issue. Here are some troubleshooting tips:

• Check for leaks: Inspect all water lines and fixtures for any leaks.
• Inspect the pressure switch: The pressure switch is responsible for turning the pump on and off. If it fails, the pump may run continuously.
• Reset the pump: Turn off the power to the pump, wait a few minutes, and then turn it back on. This may reset the pump and stop it from running continuously.

Wrap-Up: Understanding Your RV Water Pump

Understanding how your RV water pump works is essential for ensuring a comfortable and hassle-free RV experience. By knowing the difference between demand and constant pressure pumps, you can make an informed decision on which type is best suited for your needs. Remember, proper maintenance and troubleshooting can ensure that your RV water pump operates optimally, providing you with reliable water flow throughout your adventures.
