And even if the excrement washes away, the memory will not…

Top 5 Best RV Sewer Hose
OUR TOP PICK
OUR TOP PICK
Our champion sewer snake is a monster 20 feet long, meaning you could probably dump from round the corner. You shouldn’t...but you could. This kit comes fully set up and ready to use, but if 20 feet sounds too long for you, just split in half. This hose is actually two 10 foot sections that connect via a secure central joint.
The hoses themselves are made out of a super heavy-duty 18 mil HTS vinyl, so you can forget about cracks or holes. Thickened vinyl is ideal for the job here because it’s lightweight, deals well in different temperatures, and spray cleans really easily.
You’re also going to get a load of security from the joints of this kit. All connections feature both a lug and bayonet fitting. The chance of seepage or spray from a loose connection is pretty much impossible.
The thing we love but are also disgusted by here is the transparent sewer elbow attached to one end of the hose. This is the right angle joint that connects up to the dumping station.
This see-through joint lets you know if the waste is flowing consistently. If it’s clear, you’ll know there’s a blockage in your system. As smart as this design is, it also means you have to look right into your waste.
The sewer elbow also comes with an easily attachable 4-in-1 adaptor that will fit any 3” slip or 3”, 3 ½ “, or 4” NPT threaded sewer connections. Both ends of this hose have a 360-degree swivel function that makes setup a breeze, and it all folds down really small for storage.
- Full kit comes assembled and ready to use
- See through sewer elbow lets you know what's going on
- Durable 18 mil vinyl construction
- Extra secure double fit connections
- 4-in-1 adapter fits most dumping stations
- Comes with clear extender so you can check if your tanks empty
- Can be made long or short
- Comes with easily fitted caps
- Quite expensive
Coming in at the number two spot we have an awesome sewage spitter ready to get your RV clean and clear. This design is made of a high quality, durable TPE material. TPE is a thermoplastic polymer that combines the best aspects of plastic and rubber.
In this case, you’re going to get the durability and flexibility of rubber, mixed with the aspects of plastic that make it lightweight and easy to sterilize. Thetford claim this hose is uncrushable, that it can be run over by a car and still bounce back into shape.
You get a full fifteen feet to work with here which should be more than enough, and one end features an extended grip which is a cool ergonomic addition. You also get the see through sewer elbow with this kit which is great.
Titan opted for an elegant frosted finish over the perfectly clear style of our number one pick. We like this because you can see that everything’s working without having to witness it in high def.
One way this hose outshines the Camco is with its adapter. You get five different applications out of this one, meaning you’re definitely going to find a fit no matter what sort of dump station you’re at.
- Resilient TPC construction
- Easily rinsed and sterilized
- Easy fit nozzles
- Ergonomic extended bayonet grip
- 5-in-1 adapter means it’ll work at pretty much any dump station in America
- Frosted sewer elbow lets you see things are working
- Comes with easily attached caps
- Cool green and black color scheme
- Not as versatile in its length
- No extra hold functions at the joints
Connecting your RV to the bigger systems here at number three is another awesome Camco hose. This time around the hose is a little shorter at 15 feet and it’s made from a durable HDPE polyolefin.
The RhinoFlex designs are the strongest hoses on our list. They have an equivalent rating of 23 mils high tensile strength vinyl.
You're going to be able to collapse this hose down to about 56 inches, which we think is awesome for a 15-foot hose. You’ll probably have more than enough space to accommodate it in your bumper, or if you have one, a hose carrying attachment.
The thing we think makes this hose special is the steel wire running throughout, reinforcing the plastic. This will make it marginally heavier but a whole lot stronger.
Again, you get the transparent sewer elbow to give you eyes on the situation, and the swivel lugs. It also comes with some really secure fitting locks.
Once this thing’s hooked up, it’s staying on until the job is 100% complete. It also has the same 4-in1 adapter as our number one pick.
The one thing this kit is missing is a bit of versatility, but what you miss out on there, you make up in build quality and durability.
Due to the more expensive components, the price tag is a little steep - It actually costs more than our 20ft first choice, but this hose will probably set you up for life.
- Reinforced with steel wire
- Comes with transparent sewer elbow
- 15-foot length should be just about enough for any size RV
- Secure locking fixtures keep everything in place during the dumping process
- 4-in-1 adapter will be compatible with almost any dumping station
- Comes with hose caps
- Quite expensive
- May not be as space-friendly as others the same length
Coming in at the number four spot we have something of a miniature maestro perfect for all you owners of more humble vehicles with portable holding tanks.
This 3-foot long hose is perfect for draining those tote tanks quickly and easily.
It has the same super impressive steel wire and polyolefine construction as our 23 mil number three pick so you know it’s strong as a python.
It comes with really strong lock-in connections that even manage to stop the release of foul odors during the dumping process. Pretty impressive, right?
Each end has four bayonet prongs for extra security when fastening the lugs, so the chances of dislocation during a dump are slim to none.
It comes with a similar translucent sewer elbow as its bigger siblings but with some neat customizations that make it more suitable for use with a tote tank.
Camco have made the elbow incredibly low profile to help facilitate downhill flow and prevent unnecessary kinking.
This hose would be pretty easy to store fully extended. It just so happens that it collapses down to a very storage-friendly 19 inches.
- Compact design collapses to 19 inches for storage
- Reinforced with steel wire
- Perfect for those with portable holding tanks
- Extra secure odor-tight connections
- Low-profile sewer elbow for downward flow
- Includes storage caps
- Not suitable for static holding tanks
Keeping things sanitary at the tail end here is the perfect bit of gear to enhance your existing setup. It’s another high-quality Camco design, but this time it’s an extension.
It comes with two high quality swivel lug and bayonet holdings meaning you shouldn’t have any problems with disconnections or leakages.
If you’ve had problems in the past with the length of your existing hose, this will appeal to you. You get a whole ten feet of extra hose in this extension, and it’s made of heavy-duty 15 mil vinyl.
You can also expect a really compact minimum length. Collapsing this hose helper down to an incredibly practical 2 feet, you’ll be able to fit this next to your other hose in your bumper.
This extension is obviously designed to fit onto the Camco Revolution Full Sewer Kit.
We’ve used this as an example of a great quality extension hose, but you can get extensions to match any of the 20ft Camco sewer hoses.
You may even be able to use this as a stand alone hose if you buy attachments separately and you think it’s long enough.
- Can give you an extra 10ft sewer hose length
- Made of heavy-duty vinyl
- Collapses down to 2ft for storage
- This isn’t a standalone hose
- Will probably only fit Camco hoses
Best RV Sewer Hose Buying Guide
Shopping for an RV sewer hose can get pretty confusing, especially if you’re new to the scene. There are different sizes, materials, prices, and brands. How can you tell what’s good and what’s not? Well, don’t worry. In this buyer’s guide, we’re going to run through some of the things you should be considering before you commit to a product.
Budget (or not)
Normally a budget is a good idea no matter what you’re shopping for, but in the case of sewer hoses, we recommend going the whole hog. They never run all that expensive, and most of the time, throwing in an extra $20 or so will get you a top quality product.
The perfect RV sewer hose will have a full extension of 15 to 20 feet. This should be more than enough to reach from your tank to a dumping station connection.
Ideally, you don’t want to use the full extension as this will put more pressure on the hose and the fittings. That’s why we recommend getting a slightly larger hose than you think you’ll need. You could also check to see if there are extension options for your hose on the market. If there is not, as long as you have space, you could buy two of the hose and connect them up.
The smaller a hose collapses down, the easier it’s going to be to manage and store. It’s usually recommended that you keep sewer hoses in your bumper space, so you need to take some accurate measurements and match them up with the products.
If you don’t like the idea of storing the hose in the bumper, or if you have limited bumper space, you can fit a hose holder to the underside of your RV.
Strong connective sections are essential. You don’t want to entertain the thought of a leak or a complete disconnection. The consequences would be dire and disgusting.
Fortunately, most decent sewer hoses come equipped with quality connections and some kind of fail-safe or lock for extra security. Always check what extra measures the company provides. Our number one Camco hose is a great example of a hose with quality connections. It features a dual-fit design at each end.
Not all dumping stations will have the same connection. Buying a hose with a 4 or 5-way adapter will give you the freedom to dump at pretty much any station.
A sewer hose isn’t the only hose you’re going to be lugging around the world in your RV. You’re also going to have a selection of water hoses and perhaps a gas hose. It’s important that your sewer hose is stored separately from your other hoses to prevent cross-contamination
There are a few main hose materials. There is rubber, various thermoplastics, and nylon. You’ll almost exclusively be looking at thermoplastic hoses in this case. Thermoplastics tend to be a lot more flexible and durable than typical plastics, making them the perfect material for your sewer hose.
The problem is, there are a lot of different thermoplastics. Vinyl is the most commonly used thermoplastic in sewer hose production, and it’s a pretty competent substance. TPE is another material you can expect to encounter. This is a fantastic material as it combines the best aspects of plastic and rubber.
Once you’ve done a little bit of research on the material, you’ll need to know how heavy-duty the hose is. This is expressed in either ply-rating or mils. The higher the ply or mil, the more durable the hose.
We recommend you never go below 15 mils. 12 mils are fairly good hoses, but not heavy-duty enough for peace of mind. 15 mil hoses are really good. They’ll be suitable for fairly frequent expeditions. 18 mil is the sweet spot.
They’re perfect for those who travel in their RV a lot. They’re suitable for frequent use. For the strongest possible hoses, you should be looking at 23 mil and above.
Kit or Separate
We highly recommend buying an all-inclusive kit over individual parts. This will mean everything is compatible. Kits normally come with everything you could possibly need for quick and easy setup.
If you do buy separately, we recommend buying new attachments or extensions from the same manufacturer as the hose.
Best RV Sewer Hose - Frequently Asked Questions
Where should my RV sewer hose be?
Sewer hoses are typically stored in bumper spaces. That’s how most companies will illustrate a long hose’s collapsible length, rather than giving it in feet or inches. For example, they may say a 20-foot hose can be stored in 4-inch square bumpers.
Some people don’t like the idea of keeping their sewer hose in the bumper and fit dedicated sewer hose storage facilities underneath their RV
How do I sanitize my RV sewer hose?
It can be quite an arduous process but you can take steps to make it easier on yourself. Always drain your black water first. The grey water then rinses the worst of the residue away. Remove all connections, rinse them, and set them to rest in hot water and bleach. After a few hours, you can remove them, rinse them, and set them to air dry.
Rinse out your hose with clean water, then fill it with warm water and bleach. Attach both caps and try and shake the water inside so the bleach reaches every area. Leave it to soak overnight. In the morning, empty it, rinse it with clean water and leave it to dry.
Well look at that...we’ve run out of advice. Hopefully, we’ve covered all the basics here. Now you can shop and travel with confidence. A quality sewer hose is such an essential bit of gear, especially if you spend a lot of time on the road. It will save you time, effort, embarrassment, and money, leaving you to happily roll on.
