Why is my rv water pump not pumping water?

water pump not working

A water pump is a mechanical device that creates a low pressure area to force water out of a tank. It's commonly found in homes, vehicles and other establishments where water is required.

Low-pressure water pumps are also used to pump milk and other liquids, and to evacuate gas or oil from containers. Low-pressure pumps are powered by electricity, gasoline, diesel fuel or other energy sources. RVers often have an onboard water pump that they can use to refill their tanks while traveling.

Water supply systems in motor homes are typically independent of public water sources. Most RVs don't have a connected water system; instead, their water supply is usually independent of the main water tank. An RV owner must refill the water tank from an authorized source if he needs more water. The tank may also need a filter to remove mineral deposits from the water. Low-pressure pumps provide an easy way for RVers to get fresh water without needing to connect to a public source.

  1. Water Pump Failure

  2. If you are noticing no water coming out of your RV's faucet, then chances are your water pump has failed. You should have been notified by your mechanic that a check-up was performed on your system. If they did not notify you, then you need to contact them immediately. Most campers don't realize how important their water pumps are until after they lose water pressure. A working pump will keep your plumbing systems functioning properly (like toilets flushing) and allow you to shower without getting a headache.

  3. Unplugged

  4. You might think that if you unplug your rv water pump, it would run fine. However, that is incorrect. While unplugging the pump will free it, you will still need to pull the battery cables off of it before plugging it back in. Your RV water pump draws electricity from your batteries, and when you power down the batteries, you kill the voltage. Therefore, the only way to get your pump running again is to remove those cables and replace the battery.

  5. Broken Connector

  6. Your RV water pump uses a connector to connect with your water tanks. When that connector gets broken, water won't flow. To fix this issue, you'll need to purchase a replacement connector. It may take several tries to find the right size connector, and you will most likely need help. Also, make sure to test your connection before purchasing a new one. You never know when the last try worked, and your leaky faucets could just be the result of a bad connection.

  7. Damaged Conduit

  8. One of the best ways to ensure that your water flows is to install a new conduit. In order to do this, you'll need to cut away any damaged parts in your existing water hose. Once you've done this, you can use a vinyl cutter to create the new length of hose.

  9. Leaking Hose

  10. When your RV water hose starts leaking, you'll want to turn off the switch and turn the water off at the main valve. Then, drain the tank and inspect your hose for leaks. If you cannot locate where the leaking is occurring, you may need to replace your entire hose. Even though the price tag is steep, it's really the best solution.

  11. Dirty Filter

While your RV water filter seems to work perfectly, sometimes dirt builds up inside the unit and stops the flow of water. Make sure to clean the filter regularly to prevent this problem.

How To Tell If You Need To Prime Your Water Pump

If you observe your RV water pump, and it does not seem to be putting out as much water as it once did, it may be time to prime the pump. Priming the pump will help it to work more effectively.

One of the first things you should do if your RV water pump is not pumping water is to prime the pump. Priming the pump means to fill it with water and run the pump wheel to circulate the water around the pump. If the pump is not priming, there may be something clogging the pump impeller or the pump wheel. If the pump wheel is not turning, it is probably because the pump blade is not resting in the impeller. A broken or worn out pump blade will not allow the pump wheel to turn.

How To Pick The Best Rv Water Pump For Your Rv

If you are thinking about upgrading your RV's water system, there are a few things to consider before purchasing a new pump. Here are a few tips to help you select the best one for your RV.

The size of the pump

The first thing you need to do is decide the size of pump you need. Most standard RV water pumps are either 1/2 or 3/4 horsepower. If your RV has a septic system,then you may also need a 5 or 7 horsepower pump.

The size of the water pump is important, as the pump must be able to fit in the RV's water tank. Some water pumps are small enough to fit in a small RV water tank, while others are big enough to fit in a larger RV tank. This is important because the larger the pump, the more water it can move.

The installation type

Your RV water pump can be installed permanently or as a portable unit. If you are installing the pump permanently, you will need to consider the wiring required. Portable pumps are more convenient, but they may not be suitable for installations in tight spaces.

The warranty

Finally, consider the warranty offered by the pump manufacturer. Many RV water pumps come with a warranty of at least one year. If you have any questions or concerns about the pump, don't hesitate to contact the manufacturer. They will be happy

The right RV water pump is essential for keeping your RV properly watered. There are many factors to consider when choosing a water pump, including size, power, and affordability. Here are tips to help you choose the best water pump for your RV.


The power of the water pump is also important. Higher-power pumps can move more water per stroke, which is important for larger RV water tanks.


Finally, affordability is a factor to consider. Some water pumps are more expensive than others, but they may be it if they are more powerful and fit in a larger RV water tank.

How long do RV water pumps last?

The length of time your RV water pump stays operational depends on how much power it has. Most RV water pumps have low-power motors that require little maintenance. These types of motors can run for years without needing any preventive maintenance. However, your RV water pump may need occasional service if it has a high-power motor.

How Do You Prime An Rv Water Pump?

There are simple steps you can follow to prime your water pump. Follow the steps below and you will be on the right track.

1. Fill Your Freshwater Tank

Fill your freshwater tank before beginning any work on the water system. If you have not done this yet, do it now!

2. Turn On The Cold Water Valves

Turn the cold water valve on each faucet in turn until you reach the end of the cold water line (the last fixture). It should be set at about 15 degrees C.

3. Turn On Your Water Pump

Turn on your water pump. Ensure that the pump handle is turned all the way to on position and that the switch is in the on state.

4. Let The Pump Run

Let the pump run for between 10 minutes and half an hour. After the pump runs for some time, check if the water flow rate is steady. If not, then adjust the speed control knob accordingly till the water flow rate is consistent.

5. Repeat With All Water Tabs

Repeat step 4 for all remaining water taps.

How Do You Inspect Your Rv Water Pump?

  1. You should always remove your RV water pump while servicing it.
  2. Use a tool to loosen the screws holding the pump assembly to the frame.
  3. Once you've loosened everything, carefully separate the pump from its mounting base.
  4. Remove the old pump and inspect it for cracks, corrosion, rust, and debris.
  5. Make sure the gasket between the pump and the tank is still intact; if it is cracked or worn, replace it.
  6. Inspect the impeller for defects and wear.
  7. Clean off the area around the impeller with soap and warm water.
  8. Rinse thoroughly until no soap residue remains.
  9. Dry completely with a clean cloth.
  10. Install the new pump and tighten the bolts securely.

How long does it take to put my rv water pump back together?

It takes about 30 minutes to complete the replacement process. Reinstall both the drain hose and filter housing. Tighten the nuts to secure them. Put the cap back on the intake valve and turn the switch clockwise to open the water intake. Turn the switch counterclockwise to close the water intake. Close the drain valve and check the pressure gauge. If the pressure is below 10 psi, then you need to adjust the pressure valve.

Can I use a garden hose to prime my rv pump?

Yes, you can use a garden hose to help flush out your rv water pump. Run the hose from the front of the pump to the rear of the pump. Be careful not to get water in the electrical connectors or other components. When finished, let the water drain away from the pump.

What size hose should I use?

A standard garden hose should work fine to prime your rv pump. Remember to keep it clear of any obstructions. Larger diameter hoses offer greater flow capacity and are therefore preferred.

How long does it last?

RV water pumps are designed to operate constantly at high pressures, even when there is no demand for drinking water. Because of this, they are built to withstand the constant strain and may need to be replaced less often than conventional residential water systems, which might only be turned on once a week or month.

Can you repair an rv water pump?

Yes, you can repair an rv water pump. Water pumps are designed to move water through pipes - they are basically just electric motors that spin a shaft attached to a vane inside the motor. When they work properly, they create pressure between the moving parts and cause water to flow down the pipe. If the water comes out in spurts instead of flowing steadily, something must have gone wrong with the pump. Water pumps rely on seals, bearings, and lubrication to keep them running smoothly.

In order for the water pump seal to do its job properly, it needs oil to stay slippery. Without oil, the seal won't slide easily over the gears or shaft, causing friction. The best way to fix this problem is to add some oil to the seal. You can do this either when the pump was manufactured (if possible) or at any time later when you are doing repairs.

An RV Pump is only good if the bearing rotates freely. A bearing that doesn't rotate correctly could damage the pump and make it need replacement eventually. To check whether or not the bearing rotates freely, use a flashlight to look under the bearing. Make sure that the flashlight illuminates the entire area where the bearing sits. If the beam does not illuminate the whole thing, then the bearing may be stuck. If so, you'll need to disassemble the pump to get a bearing tool and try to extract it manually.

Bearing types

There are two different types of bearings for RV pumps: ball bearings and roller bearings. Ball bearings are normally easier to install than roller bearings, but both are a type of thrust bearing. Thrust bearings are meant for high-pressure applications and are able to withstand higher pressures than other types of bearings.

Once you've replaced the bearing, it's time to grease the shaft. Greasing the shaft before installing the bearing prevents metal particles from getting trapped between the bearing and the shaft, which would stop the pump from operating properly. Look for a grease fitting located somewhere near the top of the motor. Open it and pour a thin layer of grease around the shaft. Reattach the pump and test it to ensure it works well.

Water pumps are essentially the heart of any RV setup. Without them, you can't run a refrigerator, air conditioner, dishwasher, toilet, shower, heater, hot tub, etc. Many people don't realize how many components need to work together for these systems to function properly. A lot of times, when you think about running appliances on shore power, you assume that they are getting plenty of electricity.
