Having a running water pump in your RV can be a cause for concern and frustration. Not only does it waste water and put additional strain on the pump itself, but it can also lead to higher energy consumption and potential damage to the plumbing system. Understanding why your RV water pump keeps running is crucial in order to address the issue effectively.

The water pump in an RV is responsible for pressurizing the water system and delivering a steady flow of water to faucets, showers, and other onboard fixtures. When everything is working correctly, the pump should cycle on and off as needed to maintain the desired water pressure. However, if the pump continues to run even when the water is not in use, there may be an underlying problem that requires attention.

In this article, we will explore the common causes of a running water pump in an RV and provide practical steps to diagnose and fix the issue. By understanding these causes and learning how to troubleshoot them, you can save time, money, and frustration by resolving the problem yourself.

Understanding the RV Water Pump

The RV water pump is an essential component of the onboard water system. It is typically located near the fresh water tank and is responsible for pressurizing the water and providing a steady flow to the faucets, showers, and toilets in the RV. The pump is designed to automatically activate when a faucet or fixture is turned on and shut off when the desired water pressure is reached.

Most RV water pumps are diaphragm pumps, which utilize a rubber diaphragm and electric motor to create pressure and push the water through the system. These pumps are designed to be self-priming, meaning they can draw water from the fresh water tank and build pressure without the need for manual priming.

The pump is equipped with a pressure switch that senses the water pressure in the system. When the pressure drops below a certain threshold (usually around 20-30 psi), the switch activates the pump to start pressurizing the system. Once the desired pressure is reached (typically 40-50 psi), the switch turns off the pump and the cycle repeats as needed.

It’s important to note that the water pump relies on a 12-volt power source, usually provided by the RV’s battery system. This means that if your RV is not connected to an external power source or the batteries are dead, the water pump will not operate.
