What would cause RV water pump to keep running?
I’ve had this issue with my RV water pump before, and it can be quite frustrating. After some troubleshooting, I found that there are a few common causes for a water pump to keep running:

  • Leaks in the system: If there is a leak in the water line, the pump will continue to run in an attempt to maintain pressure in the system. Check all connections and lines for any signs of leaks.
  • Faulty pressure switch: The pressure switch is responsible for turning the pump on and off as needed. If it is faulty, it may not be able to detect when the system has reached the desired pressure and will continue to run. Consider replacing the pressure switch if this is the case.
  • Clogged or dirty filter: A clogged or dirty filter can restrict water flow and cause the pump to work harder than it needs to. This can lead to the pump running continuously. Make sure to clean or replace your filter regularly.
  • Air in the system: If there is air in the water lines, it can cause the pump to run continuously. Bleed the system to remove any air pockets.
  • Electrical issues: If there is an issue with the electrical wiring or connections, it can cause the pump to run continuously. Check all wiring and connections to ensure they are secure and functioning properly.

In summary, a water pump that continues to run in an RV can be caused by a variety of issues, including leaks, a faulty pressure switch, a clogged filter, air in the system, or electrical issues. By troubleshooting these potential causes, you can identify and fix the problem to ensure your water pump is functioning properly.

What Would Cause Rv Water Pump To Keep Running?

Hey there fellow RV enthusiasts! As a seasoned technician in theworld of RV water systems, I’ve seen my fair share of problems arisewith these complex machines. One issue that seems to stump many RVowners is when their water pump won’t stop running. If you’re one ofthose folks scratching your head wondering what could be causing thisfrustrating problem, then read on for some expert advice.

First things first, let’s talk about why your RV’s water pump evenneeds to run in the first place. The purpose of the pump is to createpressure within the system so that water can flow from the fresh watertank through the pipes and out of your faucets or showerhead.

When all is working well, the pump should only run long enough tobuild up adequate pressure before shutting off until more water isneeded again. If it keeps running nonstop, however, something is clearlyamiss.

So grab a seat and get ready to learn about some common culpritsbehind this pesky problem!

Troubleshooting The Pump

Have you noticed your RV water pump continuously running? This can bea frustrating and alarming issue, but don’t worry: as an experienced RVwater pump technician, I’m here to help.

The first step in troubleshooting the pump is to examine the plumbingsystem for any leaks or damage that could be causing the continuous flowof water.

Next, it’s important to check all valves connected to the pump.Sometimes, these valves may not close properly due to wear and tear overtime.

Inspecting wiring connections is also crucial in determining whetherthere are any electrical issues causing the problem. Additionally,examining hoses for kinks or blockages and inspecting filters for clogsshould be carried out during this process.

By following these steps, we can begin to identify what exactly iscausing your water pump to run constantly.

Inspecting the electrical connections will be our next step inresolving this issue. It’s essential to ensure that all wires areproperly connected and free from corrosion or damage.

A damaged wire connection could cause power surges that lead tocontinuous pumping of water without shutting off when necessary. Let’stake a closer look at how we can remedy this situation by checking theelectrical connections thoroughly.

Inspecting The ElectricalConnections

I’ll start by checking the wiring for any signs of corrosion ordamage. Then, I’ll take a look at the terminals to see if they’reproperly connected.

Checking Wiring

Hey there, fellow RV enthusiasts!

Have you ever experienced your water pump constantly running evenwhen no faucet is open? It can be quite alarming and frustrating.

As a seasoned RV water pump technician, I highly recommend checkingthe wiring as one of the possible causes.

Start by examining hoses for kinks or damage that could result inrestricted flow.

Then, inspect valves to make sure they are properly aligned and notstuck in an open position.

Finally, evaluate the power source to ensure it’s delivering enoughvoltage to keep the pump running smoothly.

Remember, keeping up with regular maintenance checks like this willhelp prevent any potential problems down the road.

Examining Terminals

Alright, fellow RV enthusiasts! Now that we’ve discussed theimportance of reviewing wiring and checking valves for potential issueswith your water pump, let’s move on to examining terminals as part ofinspecting the electrical connections.

As a seasoned RV water pump technician, I highly recommend taking acloser look at these small but critical components. Loose or corrodedterminals can result in poor electrical contact, leading to problemslike reduced voltage and even complete failure of your water pumpsystem.

So don’t forget to check those terminals regularly along with othermaintenance tasks such as testing the voltage output from your powersource. Remember, keeping up with these important checks will helpensure smooth operation of your RV water pump for years to come!

Testing The Pressure Switch

To test the pressure switch in your RV water pump, there are a fewsteps you can take as a technician.

First, start by checking the valves to ensure they are properly openand closed.

Next, identify any leaks that may be causing the system to losepressure, which could result in the pump constantly running.

Evaluate the pressure using a gauge to determine if it is within therecommended range for your specific model.

After evaluating these factors and determining that the issuepersists, it’s time to inspect hoses and examine the pump itself for anypotential defects or damage.

It’s important to note that issues with other components of your RV’splumbing system could also impact the performance of your waterpump.

If all else fails and replacing the pump becomes necessary, be sureto follow proper procedures when doing so to avoid further complicationsor damage.

Replacing The Pump

As a RV water pump technician, one can quickly identify the cause ofa continuously running pump. It could be due to several reasons, andexamining valves is usually the first step in diagnosing issues with thepump.

If you notice your RV water pump keeps running, start by checkinghoses for leaks or damage. If no issue found, it’s time to examinevalves that control water flow through the system.

Installing hardware properly is crucial because even minor errorsduring installation can result in frequent breakdowns. Replacing filtersregularly will also help keep the pump functioning correctly.

In addition, scheduled maintenance and regular inspections arenecessary to prevent potential problems from occurring. By taking careof your RV’s water systems and ensuring they’re running smoothly allyear round, you’ll have peace of mind while traveling on long journeyswith family or friends.

Preventing PotentialProblems

As an experienced RV water pump technician, I’ve seen a lot of issuesthat can cause a water pump to keep running.

One common problem is blockages in the system. If there’s debris orsediment build-up in the pipes, it can prevent water from flowing freelyand cause the pump to work overtime. To solve this issue, try flushingout your system with fresh water regularly.

Another potential issue could be faulty valves or hoses. Check allconnections for leaks and inspect hoses for any signs of wear and tear.Make sure all valves are fully open and properly functioning.

Additionally, avoid freezing temperatures which can damage hoses andlead to leaks. Finally, check wiring connections to ensure they’resecure and not causing electrical problems that may turn on the pumpunnecessarily.

With these steps taken into consideration, you’ll have no troublekeeping your RV water pump running smoothly!


Well folks, it looks like we’re nearing the end of our journeytogether. We’ve covered a lot of ground when it comes to troubleshootingyour RV water pump that keeps running.
