Unclogging a Backed Up Toilet Holding Tank

Ask an RV Expert Banner

Question


My toilet holding tank is backed up. I turned the water off. I put chemicals in it, it’s still stopped up. Is there another lever beyond the valve?

Submitted via email


Answer


I would suggest purchasing a small plumbers “snake” and see if you can go down the toilet and possibly find the drain tube? It’s a long shot but much cleaner than the other option which is to go from the outside valve and up. If you get a long enough snake, you can leave the hose connected and go up through the hose, past the valve and to the clogged area.

Typically there is not another valve other than what is at the bayonet. Another issue might be the valve is not opening, just the handle moving, especially if it’s a cable handle/valve.

Hope this helps,

    We had the same problem. We tried “snaking” and “plunger” without success. I read on line that pouring very hot water into the toilet and letting is settle overnight might work…and it did. The hot water won’t hurt the system pipes and drain. I repeated the same procedure in the morning. Some of the toilet/blackwater tank set ups “have an “s” shape” line drain and hot water will loosen any trapped waste and toilet paper, etc will essentially dissolve. If your system has been clogged a while, it may take several treatments back-to-back. Hope this helps your problem.

    Seriously, all you need to do to unclog the black water tank drain is to install a Camco 39062 Dual Flush Pro Holding Tank Rinser with Gate Valve and backflush the drain piping to break up the blockage so it will drain out. You may need to repeat several times until you are draining clear water. Any other method will be asking for a major mess

      Had the same problem. Spent two days with chemicals, snakes, plungers with no success. Bought a back flush with gate valve and hooked up the hose to that. Ran it and tank flush system at same time and within minutes it was clear. Solution to problem? Don’t use so much toilet paper and use lots of water!

    When you have a clogged toilet, you can also put hot water down the toilet. Hot water helps disolve tissue and waste. Be patient.

    Been there. Go to a campground that has a pump out set up and have them try pumping the tank out. If you have a black tank flush, it will help to run some fresh water in through there while pumping. The problem with running a snake up there (although you may have no choice) is if you are successful, you will have a disgusting result. Note: this blockage may have occurred because you left your black valve open while on sewer hook up.

    It’s a 3 way fridge and I am trying to have it operate off my 2 batteries when it is turned on. Once I start the motorhome it will operate on battery. The spare batteries are fully charged, so do I need an auto electrician to look at the wiring.

      Hello John,

      To provide more specific troubleshooting information on your refrigerator we need the make, model, and year of your refrigerator and the rig itself. Most of the RV refrigerators used today are only 2-way, powered by 120-volt power or LP. Some of the smaller units are 3-way units using the 12-Volt DC house batteries, however they are only smaller “apartment” type units as the larger units require to much power from the typical house batteries. If it’s a larger unit such as the 6 cubic foot Norcold or Dometic models, the 2 house batteries; are probably not sufficient to work. It also depends on the condition of your batteries. If they are sulfated and not able to store at 80% or more, they will look fully charged initially, but not provide enough power to operate.

      Hello Ernie,

      You have 2 options:

      1. Run the wire from the entertainment center through the overhead cabinets on the driver side drilling holes in each side of the cabinet frame until you get to the bedroom.
      2. Drill a hole in the roof above the entertainment center and run the cable up to the roof (outside) and use a cable sleeve to run the cable back to the bedroom and come in from there. This is how most RV dealers add an aftermarket satellite option.

      Hello Thomas,

      The switches you have located above the door are battery disconnect switches. The main battery typically is for the engine or chassis battery and the Aux is for the house batteries. These are designed to provide a quick disconnect similar to taking the negative cable off when not using the rig to prevent anything being left on and draining the batteries.

    Had same problem–purchased a “Clear-View” bayonet extension with a hose fitting. It’s designed to flush the black tank for coaches that don’t have a flush built in. Simple attach a hose to the fitting, attach the extension to the valve, cover the open end and make sure the valve is open. Then turn on the water. The water should dislodge anything blocking the valve. Sometimes there is just too much solid matter in the tank. And remember with, black tanks, water is your friend..

    I traveled 6,000+ miles this past summer The trip went well with the exception of the last 500 miles in that I observed unusual tire wear on the back passenger side tandem tire. Tire wear is spotted (balding) with a portion (20 to 30%) of the outside tire tread balding as well. A very unusual and contradictory wear pattern any idea as to why?

      Hello Wilson,

      To provide more specific troubleshooting information on your tire wear we need the make, model, and year of your rig. Since you stated it’s the passenger side tandem, I assume you have a larger motorized? It’s hard to tell by the description and without seeing the actual wear, however it could be you have too much weight on the passenger side of the rig? It’s not uncommon to see bigger rigs with 1000 or more extra pounds on one side vs the other which would eventually cause uneven wear. I would suggest getting your rig weighed by individual wheel position by RV Safety & Education Foundation here: http://www.rvsafety.com

      You can go to a Cat Scale and try to place the wheels on one side and then the other, however if you do not see excess wear on the duals in front of the tandem, it might not give the correct info needed. Another possibility is the tandem has gotten bent or out of alignment and without knowing the make and model we do not know the tandem brand. If you could also send some photos of the wear we might be able to pinpoint a more specific cause?

      Hello Kyle,
      I would start by checking the 12-volt DC power coming to the back of the
      refrigerator. Both the 120-volt and LP mode needs at least 10.5
      volts for the eyebrow board to signal the control module. It’s a
      little odd that the unit will not work on 120-volt power AND tries to
      light the burner assembly? Make sure you have checked all power
      sources such as the outlet in the vent area, the circuit breakers, and the
      fuses in the module panel on the back side of the refrigerator.

    My tank also was stopped up due to lack of water being used to flushed. I filled the Black tank completely up to the pipe under the toilet. We drove to the campground (about 15 miles). And drained. The road bumps will shake the water up and possibly unclog the drain. I also put about 1 cup of Dawn in there. When filling the tank through the toilet, use a spray nozzle.

      Hello Charles,

      Many RV manufacturers are not providing a spare tire due to cost, weight, and storage. Their rational is most RV owners are not going to change their own tire on a 22,000 lb vehicle and will use a roadside assistance company like CoachNet. Personally I carry a spare and even though I typically don’t change my own tire either, I want to make sure I have the correct model available in case of an emergency for the company! I have heard stories of people waiting several days to get an odd sized RV tire shipped?

    I PURCHASED this unit used . It was 1 year old. Currently I am having a problem with the aux water pump,it does not work with the switch but does work when I connect a 12v source to the pump. I also have a on going problem with the house battery not charging when the RV is not in use. I have the disconnect switch in the use position,RV plugged into shore line, installed a new all in one converter box with fuses and breakers, checked breaker in the battery control box that is not mentioned in ANY Thor material . Battery does charge while engine is running . Got a wiring schematic from Thor,what a joke, I sure hope they don’t build RV’s with that. Does not even show battery control box or the location. I need help please. Purchased your DVD about the electrical system great help but not specific enough.

    Reply
    • Customer Service

      Hi David,

      To provide more specific troubleshooting information I need to know the make, model, and year of your RV. Also need to know what make and model of converter you installed. If the unit is only one year old, it should be under warranty as most of the OEM components such as the distribution center are covered by a 2 year warranty? Since you stated; “installed a new all in one converter box with fuses and breakers” this would actually be a distribution center with the breakers, fuses, and a converter.

      Here is how the system is designed to work. When connected to shoreline power or running an onboard generator, 120-volt power goes to the distribution center through the shoreline cord. There is a main circuit breaker and smaller breakers are used for the 120-volt appliances such as the AC units, 120-volt outlets, refrigerator, etc. There is also one dedicated to the converter which is the 12-volt house battery charger. This converter/charger senses when the batteries get down to 10.5-volts and turn on to provide a 13.6-volt charge until the house batteries get to 12.6-volts. You can verify this with a multimeter set to DC voltage and place the positive and negative probes on the appropriate terminal without the unit being plugged in. This will tell you the current state of charge of the house batteries. Plug the unit in and it should go up to 13.6-volts.

      The 12-volt DC functions such as the roof vents, lights, and LP appliances will have an automotive style fuse in the distribution center and the 12-volt power goes to the device.

      Since you referenced Thor, I assume you have a motorhome and also indicated it charges when driving. You then have a Battery Isolation Manager (BIM) which allows a charge from the engine charging system while running to the house battery, and also a jump start from the house batteries to the engine if needed. See the attached diagram.

      Here are a few questions that will help isolate the issue.
      You state the water pump will not operate. Do the interior lights, roof vent fans, or other 12-volt DC items function? If yes, then you have a defective switch or loose wire to the pump.

      If you connect a battery charger to the house batteries, does the water pump work?

      With the battery disconnect switch in the “use” position, does anything else on the 12-volt DC side function such as lights and such?

      You also stated: “Checked breaker in battery control box”? I am not familiar with a battery control box and if it has anything to do with the 12-volt house battery it will have a fuse, not a breaker? Where is this battery control box and can you send a photo of the breaker?

      If you can provide this information, we should be able to get the unit operational.

      Thanks,

      Hi Jon,

      To provide more specific information on how to manually bring your slide room in we need the make, model, and year of your RV and the type of mechanism. However, if you found the motor that operates it, chances are it’s a hydraulic slide mechanism and there should be a Hex fitting on the top of the motor for manual override. It may be covered by a round sticker or decal and there should have been a hex tip in your owners packet but sometimes those get taken out at the dealership or lost. Locate the hex connection and you should be able to find a matching bit at any parts store. Then you should be able to put it into a cordless drill and move the room in and out.

    Reply
    • Customer Service

      Hi Tom. To provide more specific troubleshooting information on your refrigerator “humming” issue we need the make, model, and year of the refrigerator. Does your refrigerator operate on both 120-volts and LP? If so, do you not hear the humming during operation on LP? There should be no difference as the 120-volt operation uses a heating element and the LP mode uses a flame. Both heat the solution and operate identical from there. If you have a humming only during 120-volt operation, then it could be an issue with the heating element? I would suggest digging a little further into where the humming is actually coming from because if you are inside the rig and hear the sound, the heating element is in the back and you should not be able to hear it. Find the source of the hum and you might find it’s not due to the refrigerator?

I can only get the cylinder to move about 1 inch. The way the hoses are routed they can only be removed from the cylinder once it is pulled out from outside under the slide. They come up through floor and run on top of floor under the frame that holds the cylinder then up through an opening in the bottom of tube frame to the cylinder inside. There is very little clearance under the frame work. There are three 90 degrees turns the hoses have to make.

    Reply
    • Customer Service

      Hello Michael,

      It all depends on the amp hours of the battery. Basic RV units come with a Group 24 battery that only has less than 100 amp hours which would run your refrigerator/freezer overnight …IF… and this is a big IF!!!, the battery is not sulfated and has maximum storage capacity. Deep cycle batteries require a multistage charge once a month to break up sulfation that can form on the plates. Your typical converter simply recognizes when the battery is at 10.5 volts and throws a 13.6 volt charge until the battery reaches 12.6 volts. This will cause sulfation and reduce the storage capacity. Larger inverter/chargers have the multistage or conditioning charge. One option would be to get a Battery Minder from Northern Tool which will condition your battery and help to hold a charge longer. Another option would be to get a new converter from Progressive Dynamics with a Charge Wizard that will also condition the battery. And finally, you might want to go up in amp hours to a Group 27 or 31 which gives you longer power capacity.

      Thanks,

    Recently bought 221 jay feather travel trailer. Found front left corner had small area where caulking had deteriorated and a recent rain penetrated into the inner compartment of the closet, that exactly is in back of the leaking roof area. So entry is clear, not a lot of damage done, but I want to seal the area with Dicor Tape, the wider stuff as soon as I can be sure the entire area is dry. Is it worthwhile for me to enter the inside area of the closet, take small section out, spray something like bleach water, mold killer in there, and then put a fan on it and let that stuff do it’s work, then when dry, seal it up. What do you think? Appreciate your help so much. Again, there is no evidence of a large damaged area, but I am aware there is the issue of sight unseen. This was an RV sold by the consignment company PPL in New Braunfels Texas and it was priced right, and I did know about this ahead of time.

    I have a 1991 that we purchased 9 years ago with 12k on it. It is in pristine condition, up until now. On one spot on the upper middle of the driver’s side there is a spot about 10 inches in diameter that is delaminating. We just got our first bit of moisture inside and then noticed the spot. How would I go about fixing it? Would PL constructing adhesive work? How do I keep pressure on it while it cures? Thank you in advance.

      Hello Bill,

      First find the area moisture is coming in from above which could be a window, roof to sidewall joint, or front cap and get it sealed. I have seen several repair facilities and even owners us PL adhesive to try and fix delamination with about a 50% success rate depending on the severity of the delamination. Yours seems to be fairly small so you might be able to fix it. You can drill a few holes to get the tip of the adhesive tube inside to add the adhesive. To apply pressure, you will need to have the unit next to a wall or pole that is sturdy enough to use a 2” x 4” against it and then to a horizontal board on the side of the rig. Truck specialty stores have a handy pole jack used for the back of the bed that works really well.

      Hello,

      To provide more specific troubleshooting information on your Dometic Servel refrigerator we need the model and year as well as more specific information on the following:
      You claim you lost power on both AC and DC. The Servel runs off 120-volt AC power using a heating element to start the process of heating the absorption solution when the inside monitor panel is on the “Auto” setting. If there is no 120-volt power, it will switch to the LP mode. When operating on the LP mode, a flame lights in the burner assembly and heats the same solution to start the process. The only DC operation is using the 12-volt house batteries to run the eyebrow board functions in both settings, and opening the gas valve in the LP mode. So there is no actual “DC” operation mode? Some of the older units ran on 120-volt, LP, and DC, however most today are only 120-volt and LP unless it’s a smaller unit? I’ve learned to never say never in the RV world!

      Next, not sure what bottom supply board you are referring to and if you had one operation before replacing the board and nothing after, I would believe there is either an incorrect replacement board, or a wire not connected? The other LP operations such as the furnace and such would not be directly related to the refrigerator so your issue is most likely in the components and wiring of the replacement? I would recommend contacting Dometic to get a wiring diagram and tracing how the wires you connected to the “bottom supply board” and double check all connections.

      Thanks,

    When dewinterizing an RV that has antifreeze in the lines, do I just attach a hose with city water and open all faucets and flush the toilet? Thank you!

    Ignition key won’t start rv. I recently got my rv back after it was stolen. I had to replace the ignition key cylinder because it was damaged from theft. I also replaced the starter and solenoid because it was bad. If I turn the key forward and crawl underneath rv and jump terminals on rv it will start. So something between key cylinder to starter is preventing engine from starting, and I don’t know what. I also replaced the ignition switch.
    Any suggestions,
    Shane

    my 12 volt power outlet and cargo light switch are not working, I checked fuses under drive side and in engine bay all good, I was wondering if the body builder wired in a replay fuse, I do see some wired outside the engine bay fuse box with a square grey Bosch printed on them. any help would be great Thanks Mike.

      Hello Mike,

      Typically lights and outlets aren’t connected to relays or resetable fuses. Relays are used to trigger something when activated and resetable fuses are used for high amp draw items like motors. I would check the connections on the back of the outlet, it is possible there is a fuse on the back of the outlet. The light switch itself could be bad or possibly the bulb. Checking the connections and voltage is the best way to go if all the blade fuses are good.

      Hope this helps,

    Adding a back up light. Has anyone added a back up light to a Coachmen Catalina RLS 303 or similar trailer? Does the plug to the car include the back up wire? If so assume can find it in the underbelly and splice into it for power when in reverse. Thanks

      Hello Steven,

      The reverse wire is going to be the center prong on the trailer cord, wire is usually purple in color. The cord goes into a junction box near the A frame, follow the cord until you find it. Gain access to the box and check all the wires. There should be a capped wire. That is the wire you need to tie into. When running the wire back, just make sure you are clear of moving parts and secure your wire with zip ties to prevent snagging.

      Happy camping!

    Has anyone changed out the fuel pump on an 36′ 1996 HR? Where on top on the gas tank is it located? Middle,Left,Rt.? How difficult is it? I’ve replaced plenty of fuel tanks on vehicles, so I’m no novice, but RV’s a little different and costly to have others do it. Please help if you can.

      Hello,

      I have seen some units that will actually have an access panel to the top of the tank above the pump location, if it does not I would recommend dropping the fuel tank to gain access. I have seen them on the front passenger side of the tank and even more towards the center. I don’t recommend cutting holes into the floor to find it. Dropping the tank is the best option. Once you get to it, they remove and install the same as on trucks.

      Hope this helps,

    RV Make: RVision, RV Model: Max Sport 19', RV Year: 2007, Brand: Paralalax Power Supply, Model Number: 7100

    The PPS 7100 above has a weird problem. Whenever I plug into shore power, it fails to start the battery charger. If I cycle 120V power to the unit a few times, the converter kicks in and the 12V lights get brighter indicating a higher charging voltage. This measures about 13.7V when charging. This problem occurs whether I’m on grid voltage or our small generator. Also, it seems to be getting worse over time and now requires quite a few cycles of the circuit breaker before the charging system starts working. I’d rather fix the problem than replace the whole unit, so I’m looking for ideas on how to troubleshoot the problem. Thanks.

      Hello,

      I would start by checking the 120-volt power coming into your rig with a multimeter and then checking your house batteries? If you have low voltage, the parallax converter will default to a non-charge. Possibly “cycling” gets it to kick in. Otherwise it’s a weak converter, good news is you do not have to replace the entire distribution center, rather just the lower converter. We have a video showing this procedure and I see several systems for sale under $200. I would suggest contacting Parallax at 800-443-4859
      They are a great company to work with.

      Hello,

      Do you know if it’s coming from the ceiling at least? Where is getting wet in the room? If it’s close to the wall, it could be a window leaking. What else is on the ceiling in the room? Anything else that goes to the roof like a TV antenna? If it was leaking at the AC the gasket could be bad but if they replaced it, they would have put a new one on. Does it only leak when the AC is running? Does it only leak when it is raining? I’m sorry to ask for so much info, but the more we know about the room and conditions, the more we can help you.

      Thanks,

      Hi Karin,

      Do you know where the leak is coming from? Fan vent? Piping vent? Antenna? If you know where the leak is coming from you may have to remove the item in questions and clean off all old sealant and putty tape. Apply new putty tape, installed and reseal with a self leveling lap sealant. The antenna, if a crank up antenna, has two parts to it – the mount and the antenna with gear crank. In between the two, there is a plastic gasket and an rubber gasket below that. If they fail and water sits on top of the antenna water can get inside. You may have to remove the antenna to check if that is where the water is coming from. Also check a radio antenna too. Is water coming from the ceiling or down the walls? If you have a roof mounted AC, the gasket could be bad and need changed out. Do you have a wall mount AC unit? Those can leak inside very easily if the unit is not level and the drain plugs are clogged up. You may have water getting in the seams on the side rails on the roof, marker lights, awning rail etc. I’m sorry I can’t help more without seeing where the water is coming from.

      Thanks,

      Hi Gary,

      Is the switch a selector switch or a disconnect switch? If you have a motorhome, it may be a selector switch and it is turning off your house batteries and turning on your chassis battery to operate the awning. If it creeps out then stops, your house batteries may have low voltage or are sulfated and need to have a high amp charge to clean the plates. You can check this by checking the voltage on the battery and have someone push the button for the awning, if you see a drastic drop in voltage you may need to equalize the battery to get it to hold a better amp draw.

      Hope this helps,

      Hello,

      Is this a travel trailer/5th wheel or a motorhome? A travel trailer and 5th wheel gets the lights through the 7-way, into a junction box and then straight to the lighting assembly. There won’t be any fuses on the trailer but the towing vehicle will have fuses and relays to go to the 7-way. You will want to check those as well. Check the 7-way prongs and then the wires in the junction box by the A-frame or in the pin-box. Most common is debris or corrosion is built up in the 7-way plug or bent prongs that aren’t getting a good connection. Other than that, it is tracing wires and removing light assemblies to try and find a bad connection or dead short. A motor home with have relays on the chassis board for each of those. Could be a bad switch on the brakes and turn signals as well. If you can tell me the year, make and model of what you have I can see if I can locate a wire diagram to further help you.

      Thanks,

    On several occasions I loose DC power to the chassis controls. Ignition is dead, gauges, dash etc. when it happens I can hear a “relay sound” under the hood in the area of the BIM and the ford fuse box. It seems that an electrical “transient” will cause it to happen and also correct itself such as connecting a battery charge to the chassis battery or connecting shore power. The rest of the coach seems unaffected. when it happens there is DC power to the fuse block.

    Question 2. Does the monitor panel read the liquid level in the propane tank or the vapor pressure?
    Thanks, kevin

      Hello Kevin,

      To provide more specific troubleshooting information regarding your DC power issue we need the make, model, and year of your rig. Since you indicated it’s a Ford, it could be a Class C or Class A on a Ford F53 chassis. In either case, the BIM you described is a Battery Isolation Manager and usually located close to the house batteries which would be in the step area of a Class A. This typically would not affect the DC operation of the ignition and other components? It’s a solenoid that has a battery cable coming from the engine battery to it and then to the house batteries. When you are driving, it provides a charge to the house batteries from the engine alternator. If you have a dead engine battery, the spring loaded momentary switch provides a jump start from the house batteries. Not sure what you mean by an “electrical transient”? And I’m not sure how connecting to shoreline power would make it work as that cord goes directly to the distribution center with circuit breakers to 120-volt appliances and the converter to charge the house batteries and is completely isolated from the chassis components? If hooking up a 12-volt booster or jump to the system makes it work then I would replace the batteries? Batteries are deceiving, they can show a full charge with a meter sitting but if they are sulfated or weak, they will drop off immediately when a load is applied.

      As for the LP monitor, it indicated the level of liquid propane in the tank.

      Hope this helps,
