Why Is My RV water pump surging?

A pulsing RV water pump is a fairly common occurrence, and not necessarily an indication of the system malfunctioning. The pump will pulsate when it is trying to regulate the water pressure while the system is in use. Pulsing simply means that the system is fluctuating between high and low pressure.

Why does my water pump keep pulsing?

Usually, well water pulsates when there isn’t enough air pressure in the tank. The two parts that regulate this pressure are the electric pressure switch and the internal air bladder inside the water tank. If either of them is malfunctioning, this can cause the water from your taps to pulsate rather than flow steadily.

What causes a water pump to surge?

Over time, the air in a simple well tank will be absorbed by the water. As the amount of air in the tank decreases, the tank looses its ability to hold pressure, and the well pump on-off cycle time decreases until the pump cycle causes surging at the faucets.

How do you fix surging water pressure?

When using the water, the pressure will range from normal to brief surges when the pump motor is running. Shutting off power to the pump and draining the water tank will usually solve the problem.

To fix this, first make sure the air volume control valve is not dirty or leaking.

Why is my water pump short cycling?

The most common cause of water pump short cycling is a loss of adequate air charge in the water tank.
