Expert Answers about RV Black Tank Cleaner


  • Maintenance of Horst Miracles Probe Sensors for RV Black Water Tanks
  • It sounds like the probes on your Horst Miracle Probe Sensors for RV Black Water Tanks, # T21301VP have been introduced to something that has caused damage to them. Possibly from a harsh chemical cleaner that ate away at the plating. You may need to consider replacing them. I have included a couple of help articles that we have posted on the site that walk you through the steps of cleaning and maintaining a waste tank. The Valterra Sensor Power Sensor Cleaner, # V22011 is my recommendation...

  • Troubleshooting Tips For A Generator That Won't Start
  • If your 4,500-Watt Portable RV Generator # 333-0005 is not wanting to start you can try the following troubleshooting steps: 1. Fuel selector switch set to OFF (O) position. Set the fuel selector to either GAS or LPG. 2. The indicator light is OFF or flashing red. The indicator needs to solid red to start the engine, turn the fuel selector switch to the off position and then back to either GAS or LPG. 3. Low oil level.

  • Wand For Cleaning RV Black Tank With Sensors Which Are Reading Incorrectly
  • It sounds like you either have a Sensor # T21301VP that has gone bad or more likely there is some debris stuck on the sensor that is making it think it is full. I recommend taking a Valterra Spinning Master Blaster Tank Wand # VAL88VJ and using it to clean out your black tank. This wand has a spinning tip that allows it to spray water all around the tank and can help to clear debris stuck on the sensors and walls of your tank.

  • Troubleshooting An RV Black Tank Waste Valve That Won't Open
  • If the cable on your LaSalle Bristol Cable-Actuated RV Waste Valve # 34466N4BB72GM is moving but the valve is not opening then it has been disconnected internally from the valve stopper. You are most likely going to need to cut into the stopper housing to pull it back to avoid a mess while trying to dump the black tank. You'll then need to replace the valve with a new waste valve.

  • Camco Automatic Changeover 2-Stage Propane Regulator Indicator Showing Black
  • The plunger in Camco's regulators like the Camco Automatic Changeover 2-Stage Propane Regulator for Dual Propane Tanks # CAM59005 is a plastic piece that is only red and green. If you're seeing black then the regulator is either defective or the plunger wasn't installed when the regulator was manufactured. Either way I recommend replacing the regulator with another so that you can have an accurate tank reading. If you'd like to go this route I recommend the Compact Low Pressure 2-Stage...

  • Troubleshooting A Black Water Tank Valve That's Hard To Open And Close
  • You can lubricate the valve by dumping some vegetable oil in and working the valve open and closed. If you can take off your valve without it being a huge hassle or have your valve is right at the opening I recommend using some water resistant silicone lubricant WD40 spray. If this doesn't solve your issue and you decide to replace your valve we offer a wide variety of valves like the Valterra Bladex Waste Valve for RV Black Water Tank - 3" Hub to 3" Spigot Item # T40 or valves that come...

  • Troubleshooting An RV Toilet That Allows Black Tank Odor Into The RV
  • If you're smelling your black water tank from the new toilet then you most likely don't have the seal fully compressed to the flange. On the bottom of the your Dometic 320 Full-Timer RV Toilet # DOM87FR there's a black seal that presses against the flange on the floor and makes it so that the smell can only travel up through the trap, which will have water as a barrier to prevent the smell from coming through. To fully compress the seal you'll need to tighten your flange bolts, but you'll...

  • Troubleshooting Leaking Black Water Fitting on 1969 Forester
  • The damaged outlet hole will require replacing. I believe you will need to drop the tank to see what is really wrong with the fitting to cause the leak. Then you will use the Valterra ABS Solvent Cement - 1/4 Pint # A05-0303 and I believe the LaSalle Bristol RV Sewer Slip Hub with Flange - 3" # 34466V13 to replace the broken fitting.

  • Replacement Waste Cable for RV Black Water Tank
  • It actually looks like the cable on your tank valve is broken, which is why you're getting the extra cable pulled out there in the photo. It looks like what would typically hold that cable handle in place has been stripped out possibly. I'd open it up and see what's going on back there, but in all likelihood you need to replace the cable with something like the Valterra Waste Valve Cable # TC120PB which is a 120" long cable. These do come in a pretty good selection of lengths so I've linked...

  • Troubleshooting An RV Waste Valve Gate That Is Not Opening When The Actuator Is Pulled
  • It is completely within the realm of possibilities that the actuator has become disconnected from the gate internally causing the valve to not open. The Valterra Waste Valve Body for RV Black Water Tank w/ Coupler, Seals, and Hardware - 3" Diameter # T1003PBC you were looking at will mount with four bolts allowing you to easy swap out the old valve and install this new one. An example of this valve attaching to other fittings using four bolts would be the # T50A. I recommend just replacing...

  • Troubleshooting Malfunctioning Waste Tank Sensors
  • SeeLevel offers some 7" sensors instead of the standard 12" or 16" options so you might be able to fit one of their sensors, but you wouldn't be able to bend them 90 degrees. Is there possibly a flat side somewhere on your tank that you could use to install the sensors? The sensor probe that's no longer working is most likely just covered in toilet paper or waste, preventing it from getting a proper reading. Before digging into any of the wiring I recommend trying to spray out the tank...

  • Why is Valterra EZ Valve Electric Waste Valve Tripping Breaker
  • Something getting hung up would not trip a circuit breaker on the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank # E40B-8. If you are having an issue with the breaker getting tripped the issue is almost certainly going to be because the circuit you are wired to is pulling more amps it is capable of. This valve pulls 2.5 amps so you may want to try and wire it directly to a battery if possible.

  • Troubleshooting the Fogatti RV Tankless Water Heater with E1 Code
  • An E1 code on the Fogatti RV Tankless Water Heater, # LSB64FR, is indicating an ignition failure or accidental flame off during ignition. If you had this professionally installed, I suggest you return to the installer for troubleshooting and repair. The most common causes are: - Lack of gas in the tank. If there is not enough pressure then the Fogatti RV Tankless Water Heater struggles to operate. This will go for water pressure too. - Faulty Igniter or faulty Igniter connections...

  • Trouble Shooting Hot And Cold Water Problems In Tankless Water Heater.
  • Thanks for reaching out, I have a solution for you. In regard to the Fogatti RV Tankless Water Heater - Gas - Automatic Pilot - 41,800 Btu - Black # LSB44FR. First thing I recommend is to check all the exhaust and intake locations to make sure nothing is blocked or damaged. It is not uncommon this time of the year for animals to try and make homes in the the outside compartments of RVs. Next check if it could be a low water pressure issue. If the water pressure gets to low the flow sensor...

  • Troubleshooting Camco Rhinoflex Sewer Hose that Came Apart at Locking Ring
  • I'm sorry for that horrible experience that would make anyone an unhappy camper. The RhinoFLEX RV Sewer Hose Extension w/ Swivel Lug and Bayonet Fittings - 5' Long # CAM39765 has a locking ring as you mentioned that has the directions for use printed right on it. It sounds like the locking ring fitting it to the hose was not secured properly and was most likely why it came apart. This system is designed so that you can replace the hose and keep the fittings if ever needed. Cold should...

  • Troubleshooting a Stuck LaSalle Bristol Cable-Actuated RV Waste Valve for Black Water Tank
  • You can try removing the screw, but I don't believe that's the issue. It sounds like your cable might be broken or the actual valve has just locked up or "frozen". There is currently not a replacement cable available for the LaSalle Bristol Waste Valves. You may be able to spray it down with some lubricating grease or even a cooking spray like Pam to try to see if that might allow it to loosen itself up. If there are 4 screws holding the front hub onto the valve as you can see in the...

  • How To Tighten A Loose Black Water Valve Cable On A LaSalle Bristol Cable-Actuated Waste Valve
  • In order to fix your loose cable on your LaSalle Bristol Cable-Actuated RV Waste Valve for Black Water Tank # 34466N4AB36GM, you will need to tighten the set screw that holds the cable to the valve stem. To do this. you're going to need to first loosen the set screw at the end of the cable housing (shown below). After this is done, you will then need to slide the valve actuator body off of the valve body itself to expose a yet another set screw. This will be located on the opposite end...

  • Replacement Water Heater For Leaking Atwood GC10A-4E Water Heater
  • I know it's not ideal, but it sounds like the tank is leaking and that isn't something that is offered as a replacement part, so your only option would be a replacement unit. If you're just wanting to replace your unit with virtually the same unit, you can use the Fogatti RV Tankless Water Heater - Gas - Automatic Pilot # LSB44FR for black or # LSB64FR for white. This is similar to the water heater that you have now with a 41,800 Btu heating capacity, cut out dimensions of 13" wide x...

  • Troubleshooting Cable Waste Valves Not Functioning In Sub-Zero Temperatures
  • I'm sorry to hear about the issues you are having in the cold weather. I reached out to my contact at Valterra and they said that cold shouldn't be an issue with operation unless there is moisture in the cables or if the cables have kinks or coils. The orientation of horizontal versus vertical should not be a factor. If it were me, I'd start with trying to lubricate the cable system using penetrating oil like and working it as far into the cables as you can by working them open and...

  • Manual Override on Valterra EZ Valve Electric Waste Valve
  • I reached out to the manufacturer about this question and they replied, when the EZ Electric Valve is activated, it is fully open or fully closed. There is no way to throttle the flow. However, this unit, the Valterra EZ Valve Electric Waste Valve for RV Black Water Tank Item # E1003VP, does have a manual override in case you need to have this unit be partially opened or closed, it can be done. To activate manual override, there is a pin that is able to be pulled out, then rotate the...
