What Is an RV Water Pump?
An RV water pump is a part of an RV's fresh water system. The pump sends water from the fresh tank to an RV's faucets, toilets, and showers. This is an essential component for camping in locations without a water source or a water connection at the campsite. Its even handy for a quick roadside stop because you have running water.
The pump pressurizes the water lines in the system, which means when you open a faucet or flush the toilet, it releases the pressure, and the water comes out. The pump detects the pressure loss and begins pumping to repressurize the lines. Water continues to pump through the lines until you close the faucet, and the pump detects the proper pressure in the pipes.
Why Does My RV Water Pump Keep Cycling?
There are a few reasons why your RV water pump keeps running. You'll want to take note of how often it cycles. If your RV water pump keeps running every so often, it's likely due to a slow leak in the system. You'll want to have this checked out because even a small leak can cause significant damage to an RV.
If your water pump keeps running and you have not found a leak, you'll want to check your pressure switch. These small sensors turn the pump on and off according to the pressure in the water lines. These switches have set limits and if the limit is set to high it will not turn off. Also loose wires or a failing pressure switch can cause the pump to keep running.
If your pump is cycling on and off when running a faucet this may be normal operation. The pumps come on and off based on the water pressure and it will fluctuate when flowing water.
However, before you panic, make sure no one is actively using the water to shower, do dishes, or rinse off items with an outside shower hose. These actions will cause the pump to run continuously when everything in the system is functioning as it should.
How Often Should an RV Water Pump Cycle?
An RV water pump should only cycle when using water, and the system loses pressure. If the water pump in your RV cycles when you're not actively using water, you should immediately look into it.
When you're using water in your RV, the pump will run more often the greater the water flow is from the faucet. The pump will run continuously during high flow situations like doing dishes or showering. However, if you slow the water flow to almost a drip, it will cycle very slowly and may run every 5 to 10 seconds.
If you randomly hear the pump cycle quickly every few hours it may just be that the pump is losing a little pressure internally. If you have not found any leaks this may be a normal operation for your pump, but many will not cycle at all for many hours or days if not used.

Try These Troubleshooting Tricks to Stop Your RV Water Pump from Running
If your RV water pump keeps running, you can check a handful of things before panicking. You may not have to haul your RV to a repair shop or call a mobile technician to come to you. Many of the issues are pretty simple fixes that just about anyone can take care of in minutes.
Check If a Tap or Valve Is Open
First of all, check all the taps and valves in your water system to see if one is open. Some RVers have discovered outside shower valves were left on, and the hose would release pressure sporadically. This slight pressure loss will cause the water pump to cycle for a second or two while it repressurizes the water lines.
Anytime a valve or faucet is open, the water pump will cycle. So it's a good idea to be aware of the water usage in your RV before getting too concerned about issues with your water pump.
One common mistake some people make is leaving the outside shower on and switching the pump off. The next time it's turned on it might spray water outside without you knowing it.
Make Sure Your Water Source Is on the Correct Setting
Some RV water systems have complex setups that require the adjustment of knobs and switches for them to function correctly. A knob not being positioned correctly to open a valve can disrupt the flow from the fresh water tank to the various faucets, toilets, or showers in your RV.
You may need to adjust your water system a couple of times while camping. Try using one setting while filling your RV's fresh water tank and another when camping. Check your owner's manual for any specific adjustments you might need to make on your rig when using the water pump.
Check for a Water Line or Connection Leak
If your RV water pump keeps running at regular intervals, it can be a sign of some sort of leak. The more the water pump cycles, the more intense the leak could be. So you must check your water lines or at the connections.
If you can locate the cause of the issue, it may just require you to tighten a fitting. You can often do this by using a wrench or applying plumbers' tape to the threads. Look under all of the sinks in your RV and any water connections you can locate. No matter how big or small the leak, it will likely have a puddle of water near the loose connection or leak.

Make Sure the RV Water Pump Filter Is Clear of Debris
You may not know it, but a water pump has a filter. This helps prevent dirt and debris from getting to any of the sensitive components in the pump. If it gets clogged, it can create drops in pressure in the water pump.
First, access your water pump to check for any debris. Then, unscrew the mesh screening cap and softly scrub it with a toothbrush or wire brush to clean off any deposits sticking to the filter. Finally, put everything back together and make sure it's tight.
Determine If the RV Water Pump Has a Leak
If your RV water pump keeps running, it could also be a sign of a leak in the water pump itself. This could result from a crack or fracture in the pump's casing. If this is the case, you'll likely need to replace the entire unit. However, an RV water pump is relatively inexpensive and is a simple enough job that almost anyone can do.
Make Sure the Pressure Switch Is Working
A faulty pressure switch can also cause your RV water pump to keep running or run irregularly. This could be a loose connection, faulty wiring, or a bad switch. You'll need to use a multimeter to test the connections and confirm whether the switch is the issue.
Typically only a few screws hold them in place. However, if you're in the middle of the trip, you likely won't have a spare pressure switch. Take note of your water pump's brand and specific model number to ensure any replacement part you buy is compatible.

How Do I Reset My Water Pump?
RV water pumps don't have a reset on them. However, you may have to reset the pressure switch on the water pump. If the pressure switch functions, simply flip it up and down until it begins cycling at the appropriate time. It's as simple as that.
Can You DIY Fix an RV Water Pump?
RV water pumps are relatively inexpensive to replace, typically less than $75. They're relatively simple systems that often can last several years when you take care of them. When they do fail, you can typically buy replacement parts to fix the pump yourself, as many of the pieces are pretty standard.
Because they are relatively inexpensive, replacing the entire unit may cost less than hiring someone else to fix it. By the time you pay for any parts and the labor, it'll likely cost you more than if you had purchased a new one.
