What to Do About Air in Water Pump Lines

Ask an RV Expert Banner

Question


When I use the water pump in my RV there is always air spitting out of the faucets and shower head. Why does this happen and how do I fix it? I checked and there are no water leaks. Could I need a new pump? Thanks in advance for any help.

Answer


If you have air “spitting” on both hot and cold water, it usually means a crack or loose connection on the inlet or suction side of the pump. As it tries to draw water, air is pulled in. Sometimes the bouncing around a unit gets while going down the road gets air inside lines, however this is just a temporary condition and should stop after a little while.

Most of the time you can simply purge the lines by opening the farthest faucet until a solid stream comes out and work your way back.

If the spitting is just happening with hot water, then you have air bubbles in the water heater and should relieve the pressure valve and purge the water again. Good luck!

Safe travels,

        Every time the pump comes on —- there is a lot of noise in the lines — sometimes the pump keeps running long – there is no leaks in either the cold or hot water lines

    I get a annoying squeaking from my cab overhead to the cab on the E-450(Which I think are the rubber seal between the two) and also some air sounds from the same areas.
    Has anyone else experienced this and what should be done to quite the squeak and noises??

    After emptying my fresh water tank and filling it with a mixture of water and bleech (1/4 cup per gallon for 5 gallons), my water pump runs but it does not pressurize the line so that the water will flow. I can find no leaks and just a trickle of water flows at the sinks. What next?

      Hello Terrence,

      Did you only put in 5 gallons total? If so, this probably is not enough water in the tank as it’s getting more air than water to the pump. Try filling the tank to 1/2 and see if that helps. Otherwise you will need to take the pump out and bench test it?

    My tour has a Jensen radio DVD radio system that I replaced with a new Jensen unit. The plug was different which I rewired. One extra power wire from the old unit did not seem to be required everything works. Problem is my front two TV will only turn on by pushing the on/off bottom. The remotes will not work on either set which keeps me from changing setting or just turning the TV on. Does the back TV which is not connected to the front Tv gave anything to do wither tgat power wire.

      Hi Terry,

      This is a hard question to provide troubleshooting information without actually being able to see and verify the components. First, did everything work before you installed the new Jensen unit? Typically a radio/DVD system is powered by 12-volt DC from the house batteries and the TVs are plugged into a 120-volt residential style outlet completely separate of the 12-volt system?
      Todays HDTVs are very complicated as they are designed to have several input feeds such as Antenna, HDMI, Component, and others. I have to go to my parents house about every 2 weeks to reset the input as the cable feed no longer comes in. Not to say that is happening here, however hit the input button on the remote and it will bring up a screen with TV, Component, HDMI and others. Scroll down until you get a picture on the screen. Also, check your entertainment center as you may have pushed a button on that for the feed as well? If that does not work, take a photo of the remote, one of what you see on the TV, and the entertainment center and I think we can find the problem.

      Hello Sarah,

      Do you have problems with any of the other gray water systems such as the
      shower or the sinks? If not, then you either have a restricted drain
      pipe coming off the washer, or a pipe that is to small for the amount of
      flow coming out of the washer? If it has a couple of 90 degree
      bends, it may not be able to handle the amount of water being
      dumped? Start by using some drain cleaner that is safe for plastic
      pipe, but don’t let it sit to long in the tank as it will start to eat at
      the dump valves. Also, check your roof vent and possibly change it
      out to the newer Cyclone vent. You need good air flow for the volume
      of water that is going out and the air in the lines. Then it might
      be a matter of evaluating the water flow coming out of the washer and the
      pipe size, it may not be able to handle it and you need a different
      washer? Hopefully not!

      Hope this helps,

    wondering if a person can put a filter/modify the inverter/electrical system to reduce the brown out of LED lights when the inverter cycles.

    Non LED lights are not affected. I’m told later model RV’s have been modified so they don’t have the brown out effect with LED lights.

      Hello Brad,

      To provide more specific troubleshooting information on your LED lights going to a “Brown” state, we need the make, model, and year of your rig as well and the inverter make and model? Are you sure it’s an inverter and not a converter? I have not been aware of any issues with LED lights and inverters. What could be happening is your batteries are sulfated and not storing a charge well and losing voltage? I would suggest getting a volt meter and measuring the volts of the battery when the lights are going brown? I would also question the type of LED that’s in your rig? I only recommend M4 LED bulbs or other brands that have a metal cage and are made for RVs. If your bulbs came from an Auto Parts store, those are not designed for constant on condition, rather blinking or braking and do not perform well.

      Thanks,

          Hello Brad,

          It’s possible you have the older “analog” converter and you could upgrade to the new digital type which we installed in one of the videos? Another option is to get a stand alone digital converter from Progressive Dynamics. Here is the link: https://www.progressivedyn.com/rv/power-converters/
          You can not buy directly from them, however it’s a great source of information on which style you want to upgrade to.

          Did you try a different type of LED bulb? I would suggest getting a single bulb from an RV dealer to see if that makes a difference before spending the $$$ on an upgrade?

          Thanks

      Hello Bill,

      The vent is engineered to allow air into the tank so the water can flow out. This vent is not large enough to act as an overflow, therefore the tubes. If you do not have the tubes and forget about filling the tank, the tank will eventually burst filling your rig with water? You could pinch one line, but need to be careful about filling?

      Hi Thomas. To provide more specific troubleshooting information we need the make, model, and year of your rig. Typically the water pump is in the same compartment as the fresh water tank or in the service center if you have one? You should be able to find it by turning it on and listen for the noise. The main drain is typically at the fresh water tank, however some trailer models do not have a “main” drain valve, rather small pull up valves with a wire ring found inside under the bed and lower cabinets.

    Recently had my toy hauler out and had some issues with the input water line for water hook-up. Later, When I went to use the water pump at another location, when the pump was turned on, instead of pumping water to the faucets, toilet etc it pumped it out the fresh Water fill point.

    At the capmpground with hook-ups, I took out the filter screen to clean it and there was a small rubber like ball, (just sitting loose behind the screen) that wasn’t there when I previously cleaned the screen. I was able to hook up to the city water line at the park by removing that ball. Later, when I disconnected, I put the ball back in. Then later when we went to use the water holding tank with the water pump, water was being pushed out the outside fill input, not the faucets or toilet. What is with the little rubber like ball? Is that supposed to be further down the line and somehow got pushed up where it doesn’t belong during the winter? I have tried to find information on it, but all I can find is pretty general information on the pump itself.

    Thanks

      Hello Jimm,

      Your system has a check valve at the city water connection that should
      only allow water to come into the unit, not go out. If the valve is
      defective, when you start your water pump, the water flows to the path of
      least resistance in this case the city water connection as the valve is
      not working and the water will flow out there because it’s usually closest
      to the pump. I would suggest getting a new city water connection
      with the valve, they are easy to replace and you can find them at any RV
      parts center.

      Hello Arvis,

      There are several good batteries on the market such as Trojan, Lifeline, Optima, US Battery, and even Napa which is being used by Winnebago. I would recommend any of the name brand models, but not discount brands found at home improvement stores or implements that state they are RV/Marine. More important is to maintain them and properly charge them with a multistage charge to reduce sulfation.

      Hope this helps,

Most filters are a solid plastic canister either underneath the sink or at the outside faucet and you can not see inside them? What type of filter do you have?

      Hello,

      The only way is from under the sink. You will see the water lines going up to the faucet. Make sure to turn your water off and drain the lines before disconnecting. Once those are removed, there will be a flat nut on each male end of the faucet that need removed. Twist them off and the faucet can be removed. If your faucet has a sprayer, you will have to remove the line weight and sprayer hose connection as well as the water lines. The holding nut for this style will usually be a metal nut held in place with 2 screws. Back off those screws until it is loose and then remove the nut. Pull the nut over all lines and the faucet can be removed. When re installing make sure to just tighten faucet nuts hand tight, they can crack very easily of over tightened.

      Hope this helps,

      Hello Chris,

      It sounds like it might be losing pressure and doing a quick “thump” or burp. This could be a weak diaphram in the pump allowing some of the water to flow back. Check out the videos on access to that part of the pump to test and replace. Until then, shut off your pump at night.

      Hello Christal,

      Some sinks are plumbed to the black tank. A lot of rear sinks and outside kitchen sinks go to black tanks. It sounds like there is a venting issue not allowing the water to go down. When the toilet is flushed it’s allowing the tank to depressurize which would then let the water drain from the sink. You would have to check the vent at the sink. Some go out a side wall, others come out the roof and then there are some under the sink connected to the trap. The ones under the sink are usually a round black top on the end of a pipe and can be twisted off. If just by removing this check valve vent and the sink now works, you know for sure it was the vent.

      I hope this info was helpful!

      Hello Herb,

      I would check the connections and make sure there are no leaks. Check around the pump too. There could be air getting in somewhere if there is a crack. Sometimes it does take a little bit for all the air to clear out but if it has been more than a few minutes, there could be a problem with the pump drawing air in or a crack in a connection or line. It is possible it is a gasket on the faucet as well, normally though you will see water leaking out of it somewhere if there is an opening. If the water is just coming out “foamy” there could be a lot of debris build up in the aerator screens. You can easily remove this by unscrewing the nozzle and checking the screens. You can run the water with the aerator off and see if the water looks better, if it is you would want to clean the screens and/or replace the aerator. After that you would want to check the pump, filter (if present) and all connections.

      I hope this helps!

      Dear Tom,

      Thank you for your patience. In response to your question-

      The best way to remove any broken screws it with a screw extractor. They usually come in kits with multiple sizes. They need to be pre drilled before extracted. I will post a link to a set that works well. When it comes to the screws that hold those latches in, usually you can get away without removing the old ones. If you align the bracket where it would normally go and secure it with the two good screws to hold it in place. Then, instead of installing the screws straight in because of the broken ones you can install them at an angle. This will put the new screw in next to the broken one and with the pressure of the screws next to each other, usually still allows for a good secure mount. Doing this is a lot easier than extracting the broken screw. Since those latches are typically adjustable you could always move the bracket up or down a little bit and make new holes with the screws. Just as a reminder, make sure to use putty tape behind anything being installed on the outside of an RV. This will help prevent water from leaking in. I hope this helps!

      Dear Michael,

      Thank you for your patience. In response to your question-

      The most common size water line in RV’s is 1/2″, there are some smaller and bigger though. Really there typically aren’t many things for the water lines themselves to keep on hand but having some extra gaskets that go into the swivel ends isn’t a bad idea. I see those fail more than anything else. Keeping some hose clamps is a good idea in case a pex or other connector comes loose. Check valves can fail in the city connection, but it doesn’t happen often. I wouldn’t worry about carrying extra water line, really the only time it gets damaged is when water freezes. Keeping some extra gaskets, swivel ends and clamps would really be the only emergency things I can think of that you would need. Maybe having an extra male and female hose ends in case your water line coming in has a leak or the end gets damaged would be good to have so you don’t have to leave the site to get a new hose. I hope this helps!

      This is usually caused by the valves failing internally at the faucet. If it were just one line causing the issue it could be a kinked line or a blockage but since you are having problems with both the hot and cold at the same faucet and everything else works fine most likely the problem is with the faucet itself. There could be something fixable inside depending on the faucet but most of the time it is easier to replace the whole unit.

    Has anyone had this problem? we have a 4yo Coachman toy hauler, and up until last weekend always hooked up to city water. When using onboard water and the pump, the toilet constantly runs and fills.
    this is only with the pump, and not hooked up to city water.
    I exposed the pump, and there are no inline valves to divert the water from pump to city supply…
    Any suggestions would be greatly appreciated…Greg

    When filling the water tank or just operating on a water hose or the pump, a coupe things happen when the HWT Bypass Valve is selected:
    1. Water comes out of the HWT drain with By-Pass selected.
    2. Fresh water comes out of all hot & cold faucets, except the kitchen cold water faucet. Kitchen hot water works fine. And, when I switch to Normal Flow, the kitchen cold water works fine, and does not flow when the By-Pass is selected.
    Do I have water pipes connected incorrectly or a plumbing problem?
    Or is what happens normal?

      John,

      When the tank is in bypass mode, water should not be flowing into the tank. The whole point of the bypass is to give the option of putting antifreeze into the water lines without putting it into the tanks. There could be a problem with the valve or the setup is incorrect if water is going into the tank while in bypass mode. A lot of manufactures have a label that say bypass “on” or “off”, when in “on” selection the tank should be bypassed. When the bypass is set to “off” water will flow into the tank. Hot and cold lines should not be turning off from the bypass valves. This is the point of the valves, to still allow flow to the water lines and just bypass the tank. It sounds like the valves are installed incorrectly or not functioning properly. There are many different ways for the bypass setups but I can provide the most basic and widely used configuration diagram to give you and idea of what it is supposed to do. Just comment back and we’ll email you a diagram, if needed. There are also some systems that use check valves on the back of the tank or at valves and if a check valve is stuck it could prevent water flow to a line. To me it sounds like a valve was installed backwards since water is flowing into the tank when not supposed to and a water line is cut off. I hope this helps!

    • Customer Service
      Customer Service

      Louis,

      There really shouldn’t be an air lock. The side going into the drain should be open. The only way for an air lock is if the end is clogged. There is a check valve somewhere in the line which allows water to only flow in one direction and this could be stuck preventing water from going through. You would have to find where this check valve is and disconnect the waterlines to see if water is passing through it or not. It can be on the back side of of the hose connection, at the drain or anywhere in between as they now use vacuum breakers inline as a one way flow system and these are usually in a cabinet or behind the shower surround. The manufacture usually keeps records of where these are placed if you aren’t able to find it. If you do end up just having a clog at the end you will want to use a heavy digester to break it apart until it is clear.

    Using back water pressure through the inlet line I have found 2 leaks near the manifold.
    1 is a small leak at the threaded union for the inlet line.
    The 2nd is at the control valve manifold.

      It depends on the layout of your RV. Some have side panels that can be removed, some have to get to from underneath and others the panel has to be pulled out from the compartment. Usually there is a way to get to it from the sides or underneath so look for panels with screws in them for them to pull away.

      There is a reservoir that holds the fluid, this will be by the pump. There is usually a marking of where the full level is. You have to make sure everything is fully retracted when checking the fluid level. When things are extended the fluid is pushing them out so checking when things are out will show it is low when it really isn’t.

      The tanks are fit to size based on the layout of the RV so there is no way to really get larger ones. Depending on your layout you might be able to install another fresh tank next to the other one and connect the plumbing to pull from both. As for the grey tank the only thing that can be done is to carry along a portable tank to dump into when the tank is full.

      Hi David!
      When the faucets are all turned off and the pump is still trying to run but not as strong, this usually means there is air in the system. It could be air trapped at the end of a faucet or at the intake of the pump. It is best to operate all faucets, sinks, toilets, and even low point drains. Also check the water heater and make sure it is full and not leaking. Run everything for a 30 seconds to make sure all air is out and solid water is coming through. See what the pump does now. If it still tries to run, there is most likely an air leak in the valve. These valves can be replaced but a little more you can get a new pump. If you have an inlet filter screen before the pump these are common for air leaks and it is best to replace this first before the pump.

    Installed new water pump and all worked well. A couple of days later when switching on the water pump, all I get is a trickle at each of the faucets. Unhooked lines out of pump and out of accumulator to test for pressure and all working well. Removed faucet strainers and think I have covered the bases on simple fixes.

      Hi Richard. Typically when it is just a trickle it is a kinked water line, debris in the line or air being drawn in. Make sure to check all connections to ensure they have a tight seal. Check the lines to and from the pump for any kinks. Check the strainer attached to the pump as well. It is possible there is debris in it. Since it is happening at all faucets the problem should be isolated to the pump area. You might want to take the pump apart and check the valve as well. Something could be wrong with it. We do have a great video showing how to do this.

    I have a water heater that will not light, I have cracked the gas supply and I’m getting gas there. But i think it stops at the gas valve or manifold… because I have no gas (propane) after that… and the igniter is not arching either. Any thoughts? I think I may need a new manifold and igniter. I was thinking of going tankless to avoid all this.

    Reply
    • Customer Service

      Hello. If the igniter does attempt to light and the gas valve is not allowing propane through it is possible the issue is with the control board. The control board is what opens the valve and starts the ignition cycle so when there are multiple things not working it normally points to this. On Atwood models the control board is on the front but on Suburban models it will be behind the tank in the compartment somewhere. It is possible the individual components are failing but I would start with the main control board. We do have some great videos going over this as well, I will share the link below. As for the tankless water heater, it technically doesn’t have most of the same components to operate. These are gas only systems and instead of the flame heating a tank of water it heats a long coil of water tube to rapidly heat the water as it is flowing through. When switching to a tankless heater you will also have to change the plumbing to the current tank and the output, this isn’t too hard. The hardest part would be running the controller. The tankless heaters need a controller installed to tell the tank when to turn on and at what temperature to be set. Depending on where the tank is and where you want the controller, running the wires and setting it up can be difficult. You also have to change out any water saving fixtures like the standard shower head, water has to flow fast enough through the heater to turn it on. Without changing certain fixtures you might have to run the sink at the same time while taking a shower to make sure the heater turns on. These are just some of the minor inconveniences from tankless heaters but for some people these are the better option.

Now that spring has arrived, we are trying to purge all the winterization fluids from the water lines, yet when we attach hoses to add water, and engage the pump, there is too much air in the lines and water is not coming out. We have tried hot water faucets as we read that helps, but no success. Any thoughts and suggestions? Much appreciated.

    I need access behind the false wall to get to the back of my water heater to assess some damage to my wiring. There is a false wall under my sink and there is also a half wall with thin laminate right where the heater is. Does anyone know how to remove the laminate or safely remove the false wall under the kitchen sink?

      Hello Charlotte,

      Here’s what the experts had to say about your question:

      There is usually access to the back of the water heater without much trouble. With the plumbing fittings and other components on the back there should be a way to gain access to the area. Panels that are made to be removed usually have screws in them. Sometimes there are access panels that are stapled and need pried off to gain access. These are usually attached to the back of support cleats on the side. Using a pry bar to squeeze between the cleat and panel and working around the edges helps pry them apart. If there is a shelf above the water heater, it might be best to remove this instead of a side panel. I would look around at all options and see what panel is easiest to remove without damaging anything.

      Sincerely,

    Issues with water coming out of faucets. I purchased this used and was told everything worked, but I was unable to test it. Hooked water hose and water came out of faucets. Filled fresh tank and water wouldn’t flow with pump on. Replaced with new pump and also replaced water filter and canister because it was busted. Water tries to flow then stops and new pump doesn’t shut off. I’ve looked at all the lines under sinks, tub and at pump and nothing is leaking, but I can’t get to the lines under the rv because of a covering. What could the problem be?

    Water pump constantly runs. Water only comes out at very low pressure. I don’t see any leaks at the pump or after. Fresh water works fine all around with no leaks. I have replace the pump and have the same problem. The issue has to be on the supply side right? This is a toy hauler with 110 gal fresh tank to the rear and the pump is up front. It is a self priming pump.

    All electric pumps are not working. Heat pump, replaced coleman mach motor(the windings were burnt); water pump, replaced water pump because the bottom red wire was corroded off, but the switches inside the coach will not stay on; batteries, replaced all 4 6-volt; as daughter let them all go dry. It seems all are associated with the DC side of the electricity. Help please.

      Hi Robin. The heat pump is part of the AC unit which runs off of 120vac so that doesn’t have anything to do with the 12v system and you mentioned the water pump had corroded connections which is a moisture issue not an electrical one so I don’t really think these issues are related. Having faulty batteries can cause a lot of things to not work. 12v does power the thermostat for the AC unit but everything else on it requires 120vac to operate. As for the switches, it depends on the type of switch. If they are just rocker switches and having issues, normally it comes down to loose connections. If they are momentary switches and they won’t stay on, the contacts inside might be faulty and new switches may be required. Since there was an issue with the corroded connection on the pump there could be a chance that other connections have this issue as well. I would remove the switches and check the connections, this would be the best place to start.

    Help please I’ve been broken down here for 2 weeks. Original problem a radiator hose came loose, lost appt of water. I tried making it back to my spot which was 2min away. To no avail. So let it cool down bought antifreeze coolant filled it. And still wouldn’t start. Was cranking but not starting. Put fuel in carb and would start. Friend of mine says it’s my fuel sending unit. Which he doesn’t hear turn on. So I replaced the fuel sending unit. By the way, in trying to fix problem friend kept pouring gas in carb and one time it was going to turn off and pushed the gas and “boom” it caught fire! We were freaking out trying to turn it off but wouldn cause… obviously all the gasoline. But finally we turned it off. From what I
    examined there was no really damage done a few wires which I replaced. And after I tried to start and it would
    crank but wouldn’t start. Same problem. Anyhow I replaced sending unit, which took me 2 days, as to no friends or help. Anyhow, replaced it. And replaced 1 battery cause was dead and no good. So now I try and start and it barely cranks now and can’t even try to start. I did notice “1” plug wire burnt and it cracked off. I went and bought a cheap wire from auto zone and replaced it. Can that be the problem. Cause my “2” batteries that I have in my rv show a 12.9 volt reading which usually would start my rv??

    What would cause water to fill up in my floor heater vents? I have cleaned it up and again there is close to an inch of water in there and I can’t find the source. Thank you Anna

      The ducting system is supposed to be sealed to the furnace. The furnace should just have openings to the return vent and the ducts. The burn chamber of the furnace does vent to the outside. This area can sometimes collect water but it would sit in the burn chamber and would blow out of the exhaust when turned on. If there is a crack in the burn chamber, water could be then going into the ducts. There is also the scenario of a water leak around the exhaust and water could be collected around the furnace and it trickles into the ducting attached to the bottom of the furnace. Most likely any water getting into this area would be coming from the furnace directly. For an attached water line to be leaking would be very rare. There would have to be an opening in the duct directly near a water leak. Most likely there would be water in other places as well if it were a line leak. I would start by removing the furnace and looking for water markings or the entrance of a leak from the exterior.

    My thermostat is not working correctly. I need to set it at 52 degrees to get my air conditioner to keep the temperature in my Motorhome at 74. Similarly with the furnace. I tried replacing the thermostat but that was not the problem.

    I purchased a relay box and am ready to replace the existing one but am concerned because there are 2 blue wires and 2 red wires as well as a red and black on the control side. How do I determine where each wire should be connected.

    My fresh water tank is filling up while I am hooked up to city water. My research indicates that my water pump check valve is not closing properly and allowing water to flow into the fresh water tank. Are all water pumps universal fit, I have found one at Campers World with 4 gpm and woul like to purchase prior to removing the old / defective pump. But would like to be confident that the new will fit. Also, I cannot find any video on replacing my water pump. Any help or suggestions on either of these issues would be greatly appreciated.
