Dumping camper holding tanks using an RV sewer hose is a dirty job, but someone has to do it. (Probably youuu!)

And you might as well stack the odds in your favor that you won't have one of those dump station horror stories of your own (though they do make for a fun story - way after the fact).

A quality RV sewer hose is an inexpensive piece of equipment that every RVer should have in their rig.

Well, maybe not INSIDE inside, like in the living area. Eew.

But, when it comes to buying a camper sewer hose, it pays to buy something that won't give you grief down the road.

Read on to learn which is the best RV sewer hose.

RV Sewer Hose Reviews

Chances are, when you picked up your RV from either the dealer or the party selling it, it came with a cheap (or no) RV drain hose.

You know, the kind with really thin walls that puncture easily leading to raw sewage going places you don't want it.

Not to mention those 'awesome' cheap hose fittings held on by hose clamps.

And when you go to put this 'great' RV sewage hose away, it flops around and doesn't collapse into a shorter length for easier storage.

Yeah, fun times.

Fortunately, there are RV waste hose products available that solve these issues.

The Best RV Sewer Hoses:

  • Lippert Waste Master RV Sewer Hose
  • Valterra Viper RV Dump Hose
  • Camco RhinoFLEX RV Septic Hose

Best RV Sewer Hose

Lippert Waste Master Sewer Hose

Lippert Waste Master sewer hose


  • Pretty much leak-proof if used properly
  • Uses cam locks instead of bayonet fittings
  • Hose fittings permanently attached
  • Shut-off valve at sewer drain end
  • Built-in clear discharge viewing port
  • Inside of hose is smooth, eliminating pockets that can trap debris
  • Much easier to connect and disconnect to RV sewer outlet


  • Pricey
  • Extension costs more than the initial kit
  • One time, permanent modification for installation of cam lock mechanism on your RV

First, the Lippert Waste Master RV sewer hose has a revolutionary design. It virtually eliminates the leaking issues associated with a traditional RV holding tank hose.

Second, the Waste Master utilizes a cam lock system instead of the traditional bayonet-style fittings.

The cam system is the easiest type of sewer hose to connect and disconnect. This provides a no-drip seal between the RV sewer drain hose and the RV. Camp Addict co-founder Kelly currently uses this RV poop hose.

Choose Hose Length

Things To Consider Before Making A Purchase

  • Thickness: The thickness of an RV sanitation hose is measured in mil's. A mil is one-thousandth of an inch, so a pretty small number. The best RV sewer hoses are made of thicker material, which means they have better durability and are more puncture resistant. A puncture leads to leaks, and when we are talking about leakage of human waste, the more puncture- resistant the better.
  • Storage: Where do you plan to store your RV black water hose? Some campers have bumper RV sewer hose storage. However, the opening is normally about 4x4 (inches). Consequently, this setup requires a camper waste hose with detachable ends if they are 90-degree fittings, or are too large to fit inside the 4" bumper. Lastly, if you are storing it in your motorhome's 'basement', you may not be as limited when it comes to storage space.
  • Cost: Think about it. This is a category you DON'T want to skimp on. Of course, the cheaper the RV waste water hose, typically the cheaper the components and build quality. If you skimp in this category, it might come back to slap you in the face. It's not worth the risk. The average price range for a decent camper sewer hose is between $40 and $150.
  • Waste Tank Outlet Size: Most of today's RVs have a standardized RV sewer pipe size. However, if you have an older rig, just be sure that your outlet size is the same standard size that most are sold in.
  • Hose Length: How long is your RV? The longer it is, the longer your RV black tank hose should be. Some campgrounds have the old-style dump at the end or the back of the site. You should have enough hose length so that you can reach no matter the dump situation. The longest individual RV sewer hose length is typically 15 feet, but you can always attach multiple sections together to increase overall hose length. Sometimes two hoses are necessary to reach the dump utility.
  • Accessories: When considering what sewer hose to purchase, take a close look at what comes with a particular hose. Does it have all the necessary RV sewer hose fittings that you need for your particular camper, or do you need to purchase additional items to properly connect to your rig and/or the dump station? Also, will you need a RV sewer hose support in order to keep the hose off the ground and provide a gentle downslope to the campsite ground dump hole?

Complications Attaching A Traditional RV Waste Hose

Traditional RV sewer hoses use bayonet fittings to connect to the RV drain pipe. Trying to attach and detach these bayonet fittings to a camper drain pipe is a pain in the you-know-what.

For instance, users with weak hands or those with arthritis in their joints have great difficulty in using the traditional system.

In this situation, the difficulty comes from the rotation. Rotating the camper drain hose end onto (or off of) the RV sewer outlet sometimes requires a lot of torque.

Additionally, the low positioning of your sewer outlet may make the job very uncomfortable, even impossible, if you are not very flexible and/or have a weak grip.

Bayonet Fittings

The twisting motion of attaching the traditional bayonet fitting equipped RV sewer hoses to your camper sewer causes friction on the o-ring that seals the connection.

This can result in wear on this seal and eventual leaks at this joint.

You can replace the seals (gross), but there is a better system altogether.

A Superior RV Sewage Hose: Lippert Waste Master With Cam Lock Seals

This is where the Lippert Waste Master saves the day, with its cam lock setup.

The cam lock system they use is the standard in the professional liquid transportation industry, be it sewage, gas, or similar.

After decades of use in these industries, the cam lock system has proven to be a strong, reliable seal that prevents leaks.

Therefore, if you have arthritis or just weak hands, OR you just want to guarantee a leakage-free fit, consider getting the Lippert Waster Master.

It's the only RV septic hose system with a non-bayonet fitting.

Frequently Asked Questions

How Long Of An RV Sewer Hose Do I Need?

It is fairly simple to figure out how long of an RV sewer hose you need if you use this rule of thumb: Buy at least the length from your RV's sewage dump outlet tube to the rear of your rig (plus a few extra feet).

This is because some RV parks have the ground sewer connection at the rear of the site, which can make for a long distance to drain your RV holding tanks.

While you might not always need the full length of all your septic hose sections, there are times you'll need a second section. (Lots of great campground planning out there.)

Most RV sewer hoses come in either 15-foot or 20-foot lengths (comprising of two 10-foot sewer hoses).

That said, you can purchase a separate RV sewer hose extension (generally come in 10-foot sections) if you need additional length.

All in all, having several sections of sewage hose means you can use just the amount you need but will have more in 'reserve' if required.

What Is The Best Quality RV Sewer Hose?

The best quality RV sewer hose is the Lippert Waste Master. What makes this the best sewer hose for RV use? Read the complete review to learn all about it, but here are a few highlights.

The Lippert uses cam locks to secure this trailer drain hose (also used as a motorhome drain hose) to the RV's sewer outlet, rather than traditional bayonet-style fittings. It's a MUCH easier system to use.

Also, the Lippert Waste Master has a smooth interior hose finish so waste 'bits' don't get hung up. Finally, the Lippert has an integrated nozzle with an on/off valve and a clear viewport so that you can observe the flow out of your waste tanks.

Are All RV Sewer Hoses The Same Size?

Modern RVs have sewer hoses that are the same size. These are 3-inch diameter drain hoses that come with bayonet-style fittings to connect to your trailer or motorhome.

Because the diameter is standardized, as are the way that they are connected, RV sewer hoses are universal and should fit any modern recreational vehicle.

Can You Hook Two RV Sewer Hoses Together?

Yes, you can hook 2 RV hoses together. In fact, you can conjoin as many as you want to.

Choose hoses with compatible ends. Generally, any hose with the traditional bayonet fitting will connect to any other hose with the same style fitting.

What Size Is A Standard RV Sewer Hose?

A standard RV sewer hose size is 3 inches in diameter. This is the normal size among all modern recreational vehicles.

What Size Is A Camper Sewer Line?

The size of a camper sewer line is 3 inches in diameter. The rigid pipe used for the camper sewer outlet is 3 inches, as is the diameter of sewer hoses that connect to the RV's waste outlet pipe.

How Often Should You Replace An RV Sewer Hose?

How often you should replace an RV sewer hose depends on how good quality it was to start with, and how well you take care of it.

Like most things in life, if you treat your black and grey water drain hose with care, it will lead a long life. However, if you abuse it, step on it, run it over with your car, or just are being careless with how you treat it, then don't be surprised if you are changing out the RV black water tank hose frequently.

I've been using the same RhinoFLEX RV black water drain hose for over 7 years of full-time use and it's performing just as well as the day I bought it.

Rinse your hose out after each use, store it somewhere it won't be damaged, and it will give you many years of use.

Do New RVs Come With Sewer Hoses?

New RVs may come with a sewer hose if the dealer supplies a starter kit with your purchase. Generally, the manufacturer doesn't supply a sewer hose, so it is up to the selling dealer to provide this accessory.

If a hose is included with the purchase, I'd be shocked if that black and grey water tank hose is of decent quality. Don't be surprised if you find yourself purchasing a better one almost immediately.

Are All RV Sewer Hoses The Same?

All RV sewer hoses are the same in that they are 3-inches in diameter and traditionally have bayonet-style fittings. However, the quality of materials used for both the hose and the fittings wildly vary, as does the method of attaching the end fittings to the hose.

  • Marshall, I have limited space for hose storage in my new Keystone Crossfire Bullet, like only 26″ no bumper storage, ( I know one of the cons to an otherwise pretty sweet trailer, cheap bastards). I am going to add a super slider adjustable tube storage but was wondering what length hose seems to be the best without carring too much or too little?

    • Hey David,

      Yeah, isn’t it ‘wonderful’ how RV manufacturers put so much thought into the little details that make living in, and using, their products so much easier? (insert eye roll here). There can be an argument made that most RVs are designed by people who don’t use them. Not that it shows or anything. OK, I’m done being facetious and will actually answer your question…

      I’ve had a 15 foot Rhino Sewer Hose since I launched (coming up on 7 years ago) and still have that very same hose today. As in, it’s never been replaced. I also purchased the 10 foot extension at the same time, but for the vast majority of the time, I’m only using the 15 foot hose. So, for me, a 15 foot hose does the trick.

      But keep in mind that I only boondock so I’m not having to deal with full hookup-up campsites that put the sewer outlets in weird places. For these times, you may need more than 15 feet. But since I’m only using dump stations, I can position my trailer so that 15 feet of hose is more than enough.

      So the answer depends. For me, 15 feet is plenty. For people that only camp in campgrounds that have sewer at the site, they may find themselves needing longer hose.

      How is that for a ‘it depends’ answer? 🙂

    • Hi Rrabby,

      I really like my Lippert Waste Master! Glad to give you some ideas. Thanks for the comment and Camp On!!

  • Hi,
    I have a RhinoFlex Tote Tank 3’ hose which has been used very little. Now it leaks at the 90˚ swivel which makes is unsuitable for dumping black water, only grey. Tried everything I could to make it seal, including rotating the swivel several times, wiggling it, letting it sit in the sun. Nothing. I can’t find a site to contact Camco directly so thought I would let you know so you can include this in any reviews. Thanks for a good job on this site.

    • Hey Brian,

      Sorry to hear the trouble you are having.

      Do you have the end that is removable? Or the new style that is permanently installed?

      If you have the older style where the end is removable, make sure that you have tightened the end per the video at the bottom of the Rhinoflex review.

      Camco customer service can be reached at 800.334.2004.

      Sorry for your troubles! Please let us know how this got resolved.

      • Marshall,
        I did call Camco and described the problem and offered to send photos of where it’s leaking and my purchase receipt. The fellow, Mark, I think, said don’t worry about it. He was great! Instantly, and I mean instantly, he said a new one would be sent out today. That is excellent customer service! Now if everybody would be this good……….
        Speaking of sewer hoses, I like the Valterra Viper you have on your site. I will consider it. Thanks a lot.

        • Hey Brian,

          Glad that Camco was so accommodating on the replacement. Truly great when you run into customer service that exceeds your expectations.

          Here’s hoping that the new hose will treat you right.

          Thanks for the feedback and Camp On!

  • Rhinoflex is no longer using removable ends. They now use permanently attached but very leaky connectors. They leak between connector and hose not at the swivel or at the gasket where it can be connected.

    • Hi Warren,

      Thank you for the information! We have recently noticed the upswing in negative comments about leaking. We are currently re-assessing our inclusion of the Camco Rhinoflex in our reviews. Thank you for helping assist us in keeping Camp Addict up to date and great. Camp On, Warren!

  • Love your site and the information you provide. Ordered the Valterra Viper today. I think it will be just fine. Thank you for all of the information and reviews. BTW, we ordered from your link.

    • Awesome! Thanks, Ken and we are glad that you find Camp Addict useful. The Vlaterra Viper should serve your dirty job well for years to come. Have “fun” using it and Camp On!

  • We are purchasing our first TT this week -FORest River ROckwood. So glad I came across this site. Will purchase this hose. THE customer support is aMAZING.

  • We are “newbies” reading all these articles, bought the Lippert system, want to save the embarrassment, but it will not work on my RV. After cutting the nubs and attaching the cam lock I would have to remove the cover door and drive down the road with the sewer port hanging out. Wife would not have this! Any help here. Thanks, Mack

    • Hi Mack,

      I just want to understand what you are asking. Your sewer connection is inside a bay door and after installing the cam lock there isn’t enough clearance to close the door?

      If this is the case, I don’t know what to suggest. Definitely need to check clearances before any modifications are done to an RV to make sure all fits properly.

      Am I understanding the issue correctly? If so, have you contacted Lippert to see if they have any suggestions?

    • Mac,
      May be too late, sorry I recently found this site. If you contact Drain Master 877 787 8833 toll free we will help you with your issue. If one of the techs is not familur with your coach ask to speak to me. I created the Waste Master system and am here to help RVers understand there is a much better way to do the least desirable task associated with RVing.
      With appreciation


      • Doug. We are Fort Wilderness today trying to use the Waste Master Hose that came with our new Forester for the first time. It absolutely refuses to stretch out. I cannot reach the sewer pipe no matter what I do. If I pull on it what small part of it that has stretched a bit just collapses and bends. This hose is worthless and I need help or a new hose. If it helps, the unit we purchased is one year old and had never been stretched out. I am beginning to think that there is an expiration date to the hose if it is not used right away.

        • Hi Leonard,

          Sorry to hear you have had an issue with the Drain Master. We have reached out to Doug of Drain Master about this and he is aware of this comment and should be replying to you here shortly!

        • Hi Lenard,
          The system is a closed system so when you hook the system to your RV and try to pull the hose a vacuum is created! There is no place for the hose to get air because the end connected to the RV has closed dump valves so there is no source of air from the tank roof air vent. The nozzle end of the hose has a shut off valve and is normally closed. No place to get air! By following our First in Last out rule of dumping you will have uneventful dumping in the future. Please contact me directly 831 801 4827 cell or dougATdrainmasterDOTcom and I will help you better understand the system and how it really is the best on the market.

          • Doug, thanks for the reply! I also received some guidance from some good folks in the Forest River forum realm. I actually had two newby issues. I had the valve at the head closed and I had the red shipping plug still installed. I am all good now. Thanks for the reply!

          • Hey Leonard,
            We are happy to hear that all is well with your Drain Master! Thanks to Doug for helping out Leonard. Camp On, Leonard!

          • It is great to know others in the Forest River Forum have helped you as well. Any time something new comes to market the challenge is to be in contact with the new owner to eliminate confusion. Documents supplied to the OEM never seem to make it through the system to the end user. It is sites like Camp Addict that are invaluable to being the link between us and you, the consumer, and we appreciate their efforts on your behalf.
            We specialize in RV Waste Management and welcome your questions on this important subject. Visit our web site http://www.drainmaster DOTcom or call our toll free number 877 787 8833.

          • Do not throw away the red plug! Use it to trap odors in hose. Our hose is now over 4 years (full timer) trouble free, until aqua hot exhaust caught it.
            Ordered new one today.

          • Hi Chuck,

            It sure does!! I am glad to have mine on my Waste Master. Because my hose goes into my trailer basement. Which I access frequently. BOTH ends close off, one with a handle/valve, and the other with the red cap!

            I’m thankful for it. LOL!

          • Thanks for the help, Doug! You are so committed to how amazing this hose is and we appreciate it!

          • You are more than welcome Kelly, I appreciate all the work you and Marshal do to keep our RVing family out there enjoying this special lifestyle.
