used this to extend the waste valve closer to the edge of a Lakota horse trailer with living quarters. The beefy frame of a horse trailer has a big beam that the mfg keeps the drain valve behind.

@Texasseean That's great to hear! It's always nice to be able to easily do a job that is everyone's least favorite part when RVing.

@Texasseean Glad we had something to make your life a little easier Texasseean! Enough about the waste tanks, I would like to know what kind of horses you are hauling around in that trailer? I showed a little western as a kid, would love to have some horse of my own one day!

Works well and also helps to see what is flowing out of the tanks as you service them.
by:
This has been great for flushing out both the gray and black water tanks. The spray pattern is perfect for cleaning off the black water level sensor. It is so easy to use after every camping trip to keep the tanks clean.

Need to improve hose connection

2 great products for our 6 month stay in our Airstream.
by:
The black tank valve on our Airstream is leaking so I purchased this product to use in the interim until I am able to get my travel trailer into the shop to have the failing black tank valve replaced. It was easy to install and swivels at the bayonet connection end and the valve connection.

I bought the Rhino waste blaster a year ago and I'll tell you it's truly a monster!!while draining my camper tanks I'm able to close and back flush pluse blast away any residue.. I would highly recommend the Rhino Blaster.

The plastic cracked about 6 months in and began to leak so I won’t buy this one again.
by:
Great product for RV’ers. etrailer does a great job keeping you appraised of back ordered items. Would definitely utilize them again for my trailer accessories.
by:
Great product. Perfect for cleaning and rinsing your tanks. Very quick shipping from etrailer.
by:
Love this product - I flush the tanks whenever possible and this product makes it easy to see when tanks are sufficiently flushed. The integrated valve allows backfilling of tanks to the top sensors for a good rinse.
by:
Best service and product
by:
So my black tank has been clogged for the past three weeks. We tried everything to get the clog loose but nothing worked. Ordered the Rhino Blaster, received it in the mail three days later. Got everything hooked up, turned the water on and literally five seconds later the clog dislodged and the tank drained. Worth every penny!
by:
The first time i used it one of the gaskets leaked was not happy. Took it apart and reseated the gasket worked fine after that! Thank you
by:
Super duper fast shipping! Got here in less time than we expected. Great company we have ordered from here before and will continue, Thank you so much!
by:
Product works great. Issue was with the quality control. Came with the valve screw out and the valve handle loose in the carton. Had some difficulty getting it back together. Once together, it has worked without any issues.
by:
Exactly what I ordered and shipped same day... Love etrailer!!!!

Do you have a question about this RV Waste Valve?
  • Replacement Flush Valve and Connector for 2018 Jayco Alante
    Hey Chris, For a replacement black water flush valve on your 2018 Jayco Alante 31V, you can use RhinoFLEX Rhino Blaster Pro Adapter for Rinsing RV Holding Tanks and Sewer Hoses # CAM39085. This includes the valve as well as the adapter, so it will work with the 3" bayonet fitting on your sewer hose. Can you tell me exactly what snapped? Was it the hose threads, the inlet, or something else? The RhinoFLEX adapter is made of polypropylene and polycarbonate, so I really think it's going...

  • Does The Camco Rhino Blaster Pro Need Lubricant On The Gate Valve?
    Hey Mike, Yes, with any valve like that on the # CAM39085 it needs to be lubricated to keep if from sticking or misplacing the seals. Any silicone-based lubricants are recommended for this application. I am not sure exactly what brand Camco uses, but as long as it is a silicone-based lubricant it is going to work well for you. You'll want to check these after any long trips or longer periods of time where you are not using it. Do you travel often and think you will use this a lot?

  • Recommended Extension Adapter for the RhinoFLEX Rhino Blaster Pro Adapter CAM39085
    Yes, there is! The 7" Camco RV Sewer Hose Straight Adapter w/ Lug and Bayonet Fittings item # CAM39582 is exactly what you need for your RhinoFLEX Rhino Blaster Pro Adapter for Rinsing RV Holding Tanks and Sewer Hoses item # CAM39085.

  • Which End of the Garden Hose Does the Vacuum Breaker of the RhinoFLEX # CAM39085 Install on
    The vacuum breaker will need to be installed on the RhinoFLEX # CAM39085 end of your hose. You can see this demonstrated in the attached review video. If you were to install it on the faucet end of your hose then there wouldn't be a filter to keep things out of your actual hose parts. Installing it this way will allow you to still use your hose for other applications. You may also be interested in the Camco Quick Hose Connect # CAM20135 to make connecting/disconnecting your hose less...

  • Recommended Holding Tank Sensor Monitor For An RV
    It definitely is a guessing game when it comes to filling your holding tanks. For a much more accurate reading of the water level in your black tank, as well as your fresh and gray, you can install the SeeLeveL RV Holding Tank Monitor # SE44VR. These strips simply stick onto the outside of of your holding tanks and have sensors every inch instead of just the old 1/3, 2/3, 3/3 type sensors that manufacturers install in their RV's. Because there's more sensors on these strips the reading...

  • Should the RhinoFLEX Rhino Blaster Pro Adapter CAM39085 be Removed When Not in Use
    When not in use you would want to remove all of the RhinoFLEX Rhino Blaster Pro Adapter for Rinsing RV Holding Tanks and Sewer Hoses # CAM39085 from the RV so that you don't end up damaging it as it can hang pretty low. I attached a demo video for this for you to check out as well that shows how it installs.

  • Can the RhinoFLEX Rhino Blaster Pro Adapter # CAM39085 be Used on a Trailer or Motorhome
    Since the sewer systems on trailers and motorhomes are the same you can use the RhinoFLEX Rhino Blaster Pro Adapter # CAM39085 for both applications. It installs easily without tools but you can use the RhinoFLEX Swivel Fitting Wrench Set # CAM39758 to make it easier while wearing gloves, like part # CAM40287.

  • Can the RhinoFLEX Rhino Blaster Pro Adapter # CAM39085 be Used to Clean Out Tanks
    The RhinoFLEX Rhino Blaster Pro Adapter # CAM39085 will allow you to not only rinse out your sewer hose, but also your tanks as well. You will simply need to close the gate valve while your tank fills up and then open up the valve after it is full. This will allow the water to drain your tank and you can do that as many times as needed until you see the water running clean through the clear part of the adapter. I have attached a review video to demonstrate this process.

  • How Does the RhinoFLEX Sewer Flush Adapter Attach?
    The RhinoFLEX Rhino Blaster Pro Adapter for Rinsing RV Holding Tanks and Sewer Hoses # CAM39085 is an easy way to clean out your tank and hoses. It does not attach with glue but rather with the bayonet style fittings for easy connection and removal. It is a tool-free installation. The clear tube allows you to not only attach a hose to allow you to flush an enclosed hose, but also lets you see when the water is actually clean so you don't have a half rinsed tank or sewer hose.

As you can see in the attached review video, our team member installed the adapter while wearing the Camco RV Sewer Sanitation Gloves # CAM40287.
