Common Causes
Understanding why your RV water pump keeps turning on and off is essential. It helps in identifying the root cause and resolving the issue quickly. Several common causes can lead to this problem. Let’s explore them.
Low Water Levels
Low water levels in your RV’s tank can cause the pump to act up. The pump may try to maintain pressure, causing it to cycle on and off. Always check the water level in your tank. Ensure it is sufficiently filled to prevent this issue.
Air In The Lines
Air trapped in the water lines can also trigger the pump to cycle. This happens when the pump struggles to maintain consistent water pressure. Bleeding the air from the lines can resolve this problem. Run all faucets until a steady stream of water flows. This can help remove the air.
Checking Water Levels
If your RV water pump keeps turning on and off, the first thing to check is the water levels. Low water levels can cause the pump to cycle frequently. This is an easy fix and can save you from bigger problems.
Inspect Freshwater Tank
Start by inspecting the freshwater tank. Locate the tank, usually under the RV or in a storage compartment. Use a flashlight to get a clear view. Check the water level by looking at the gauge or the sight glass.
If the gauge shows low water, the pump might be cycling due to insufficient water. This is a common issue and easily fixed.
Fill Water Tank
Next, if the water level is low, fill the water tank. Attach a clean hose to the RV’s water inlet. Turn on the water supply and let the tank fill up.
Monitor the tank closely to avoid overfilling. Most RVs have an overflow valve, but it’s best to be cautious. Once the tank is full, check the gauge again to ensure it reads correctly.
After filling, check if the pump still cycles. Often, a full tank resolves the issue. If the pump continues to turn on and off, there might be other issues to explore.
Inspecting For Leaks
Experiencing your RV water pump turning on and off frequently can be frustrating. This issue often points to leaks in the system. Inspecting for leaks helps to identify the problem and fix it. Follow these steps to ensure your RV water pump runs smoothly.
Examine Plumbing Connections
Start by checking all plumbing connections. Look for loose or damaged connections. Tighten any loose connections with a wrench. Replace damaged parts to prevent leaks. Ensure all connections are secure and free from cracks.
Check Water Fixtures
Next, inspect all water fixtures. This includes faucets, showerheads, and toilets. Turn each fixture on and off. Listen for unusual sounds. Look for water drips or pooling. Fix any leaks you find. Replace faulty fixtures if needed. A small leak can cause the pump to cycle.

Air In Water Lines
A common issue faced by RV owners is the water pump turning on and off frequently. The usual culprit? Air in the water lines. This problem can disrupt the water flow and cause the pump to work inefficiently. Let’s explore how to resolve this by bleeding the system and priming the pump.
Bleeding The System
To bleed the system, you need to remove the air trapped in the water lines. Follow these steps:
- Turn off the water pump.
- Open all the faucets in the RV, including hot and cold lines.
- Let the water run until a steady flow is achieved.
- Close the faucets one by one after ensuring no air is left.
This process should help in eliminating the air pockets. If the issue persists, repeat the steps. A thorough bleeding ensures a smooth water flow.
Priming The Pump
Priming the pump is essential if it continues to turn on and off. Priming means filling the pump with water to remove trapped air. Here’s how:
- Turn off the pump and water supply.
- Locate the pump’s priming plug and remove it.
- Fill the pump with water until it’s full.
- Replace the priming plug and tighten it securely.
- Turn on the water supply and the pump.
This process ensures the pump operates efficiently. A well-primed pump will maintain consistent water pressure.
Regular maintenance of your RV water system is crucial. It helps in preventing air from entering the lines. Always ensure connections are tight and check for leaks. A well-maintained system guarantees a smooth journey.
Pump Pressure Settings
Understanding the pump pressure settings of your RV water pump is crucial. This can help prevent the pump from turning on and off frequently. Properly adjusting these settings ensures a smooth water flow and extends the life of the pump.
Adjusting Pressure Switch
The pressure switch controls when the pump turns on and off. Adjusting it correctly is vital. Follow these steps:
- Locate the pressure switch on the pump.
- Use a screwdriver to adjust the switch.
- Turn the screw clockwise to increase the pressure.
- Turn the screw counterclockwise to decrease the pressure.
Check the pump operation after each adjustment. Small changes can make a big difference.
Optimal Pressure Range
Maintaining the optimal pressure range is important for efficient pump operation. Here are the typical settings:
| Pressure Setting | PSI (Pounds per Square Inch) |
|---|---|
| Cut-in Pressure | 30-40 PSI |
| Cut-out Pressure | 50-60 PSI |
Ensure your pump operates within these ranges. This will help it function efficiently and reduce cycling.
Frequent cycling can damage the pump. It is important to find the right balance.
Electrical Issues
Electrical issues can cause your RV water pump to turn on and off frequently. Fixing these issues ensures a smooth and efficient water system. This section will guide you through inspecting wiring and checking fuses, the two main electrical components to check.
Inspecting Wiring
First, inspect the wiring of your RV water pump. Damaged wires can disrupt the electrical flow. Follow these steps:
- Turn off the power supply to the water pump.
- Locate the wiring connected to the pump.
- Check for visible damage like frayed or broken wires.
- Use a multimeter to test the continuity of the wires.
If you find any damaged wires, replace them immediately. Make sure all connections are secure. Loose connections can cause the pump to behave erratically.
Checking Fuses
Next, check the fuses related to your RV water pump. A blown fuse can interrupt the electrical circuit. Here’s how to do it:
- Locate the fuse box in your RV.
- Identify the fuse linked to the water pump.
- Remove the fuse and inspect it for signs of damage.
- If the fuse is blown, replace it with one of the same rating.
Ensure the new fuse is properly installed. A faulty fuse can cause the water pump to turn on and off.
By inspecting wiring and checking fuses, you can solve many electrical issues that affect your RV water pump.
Pump Maintenance
Regular pump maintenance is crucial to keep your RV’s water system running smoothly. Proper care ensures your water pump operates efficiently and prevents issues. Below are some key steps to maintain your pump.
Cleaning The Strainer
The strainer traps debris that could damage the pump. Over time, it can become clogged, leading to the pump turning on and off frequently.
- Locate the strainer. It is usually near the water pump.
- Turn off the water pump before cleaning.
- Remove the strainer cover carefully.
- Rinse the strainer under running water to remove dirt.
- Inspect the strainer for any damage. Replace if necessary.
- Reassemble the strainer and turn the pump back on.
Lubricating The Pump
Lubrication is essential for the smooth operation of your water pump. Lack of lubrication can cause the pump to wear out quickly.
- Turn off the pump and disconnect it from the power source.
- Refer to your pump’s manual for lubrication points.
- Use the recommended lubricant for your pump.
- Apply a small amount of lubricant to the designated areas.
- Reconnect the power and test the pump.
Regular lubrication prevents friction and extends the life of the pump.
