A Deeper Look at Sewer Hoses That Will Get the Job Done
Let’s take a closer look at our picks for the best RV sewer hose. We’ll discuss each hose’s standout features, talk about things we like and don’t like, and go over the pros and cons for each.
Best Overall Sewer Hose
Lippert 359724 Waste Master
We’re going to kick things off with our choice for the best overall hose, which is the Lippert 359724 Waste Master. It offers several fantastic features that will make using an RV sewer hose a breeze, like its helical coil structure and smooth interior texture that allows for continuous waste flow.
Another excellent feature we were pleased to see is the CAM lock connector, which is a professional standard in the liquid transport industry. CAM lock connectors provide secure attachment to sewage outlets, which means you won’t have to worry about any leaks. And with the 90-degree discharge port, the user-friendly nozzle is easy to attach and position.
The Waste Master compresses down to five feet for easy storage and offers an extension of up to 20. A handy little feature is that the hose stays in place when extended. It’s also puncture resistant and UV resistant, which adds a bit more durability.
The only real drawback we could find to this model is its dimensions. It’s a bit bulky, but other than that, the Lippert Waste Master impresses in every other area.
- Easy attachment
- 20 feet long
- UV resistant
- Includes CAM lock connector
- Not the bulkiest or lightest model available
Best Heavy Duty Sewer Hose
Thetford Titan Sewer Kit
Next up, we’ve got the Thetford Titan Sewer Kit, which was our pick for the best heavy-duty RV sewer hose. If you’re an RV owner who makes frequent use of your rig, you’ll want to consider this 15-foot hose. The Thetford Titan can easily stand up to the demands of ongoing sewage needs.
There’s one feature in particular that helped cement its place as the best heavy-duty sewer hose: the use of Thermoplastic Elastomer (TPE) properties. TPE gives the hose super strength: it’s puncture and abrasion-resistant, and you can rest assured that it won’t get crushed. Plus, this hose is robust enough to use in both high and low temperatures.
This 5-in-1-sewer adapter stands above the typical 4-in-1 models by offering users greater flexibility. We also find the Secure End Caps very useful, as they make storing leaky hoses a thing of the past. Finally, the Thetford Titan comes with a 10-foot extension.
Being super strong does come with one downside, though: this hose is stiff and awkward to store.
- It won’t leak thanks to TPE technology
- The material is temperature proof
- The hose is uncrushable
- Easy sewage inlet connection
- Some users report that storage can be difficult due to the thickness and stiffness of this hose
Easiest to Set Up
Camco RhinoFLEX 20ft RV Sewer Hose Kit
For the RV owner who wants to get things done quickly, we recommend the Camco RhinoFLEX. It’s one of the easiest hoses on the market to set up, so you can be done draining waste and back to enjoying all the perks of having an RV in no time flat. This 4-in-1 detachable adapter will fit any standard sewer connection, and it comes with a lock cap to prevent dripping.
And not only is it easy to set up, but its steel wire core also makes it one sturdy hose that will stand the test of time. We like that it comes with two 10-foot options, which is great because you can use the amount of hose you need. And just like setup, switching between the two is easy.
Storage is simple with this hose because it compresses down to 56 inches. The clear elbow is another excellent feature. While seeing the contents of your RhinoFLEX hose may be unpleasant, the advantage is that it’s easy to know when the job is done.
One drawback is that while the design of the Camco RinoFLEX is quite durable, the hose still can be crushed. Another downside is that some users report having issues with the end fittings coming loose.
- The collapsible design facilitates storage
- Robust design
- Can be used as both 10- and 20-foot hoses
- Can be crushed
- There may be issues with the end fittings coming loose
Most Affordable Sewer Hose
Valterra Dominator Sewer Hose Kit
The Valterra Dominator Sewer Hose Kit made our list for being a fantastic affordable option that will get the job done. If you’re a more casual RV user looking for a budget sewer hose, this Valterra model could be right for you. This 15-foot hose (also available in a 20-foot option) impresses for its ability to resist crushing and collapse down to 57 inches for storage.
We like how simple it is to use this hose. The sewer fittings come attached, which guarantees against leaks. The fittings also spin 360 degrees, which guards against kinks, and we can find the transparent elbow on the RhinoFLEX too, which makes it easy to see when the tank is empty. And the hose features UV stabilizing technology in its design that adds durability.
All in all, Valterra has created a product that will meet all your needs. Though if you’re a more serious RV user, we’d recommend a different one because some reviews mentioned that this hose’s lifespan was shorter than others. It’s also worth mentioning that you can’t replace damaged parts, as everything is permanently attached.
- Includes one-year warranty
- Collapses easily
- Connection is straightforward
- Doesn’t have as long a lifespan as other models
- No disassembly for damaged parts
Best Sewer Hose Support
Camco Sidewinder RV Sewer Support
The last product on our list isn’t an RV sewer hose, but it’s a product that will make using yours more effective: a handy sewer hose support. The Camco Sidewinder keeps your sewer hose off the ground and, in doing so, helps prevent punctures and extends the life of your hose. It also gives it a bit of lift so that waste can flow more easily.
Setting up the Sidewinder couldn’t be any more straightforward as it comes ready to use. All you have to do is clip it onto your hose, and you’re good to go. Plus, it’s weatherproof, rustproof, and corrosion-proof, so you know it’ll be with you for the long haul.
There are a couple of downsides to mention. It may be challenging to get the full benefits of this product in windy conditions, where it may blow over. And some users complained about the hinges breaking. Despite these problem areas, it’s worth investing in this product to get better use out of your hose and extend its lifetime.
- The product comes ready to use
- Helps facilitate drainage
- Gives your hose a longer lifespan
- Some users report problems with the hinges breaking
- May fall over in windy conditions

Buying a Sewer Hose: What to Look For
Before purchasing an RV sewer hose, there are some vital factors you should consider.
Length is a critical hose feature you must pay attention to when making your selection. Most RV sewer hoses range from 14 to 20 feet, and the length of your rig ultimately determines hose length. The recommended length for most RVs is 15 feet, but if you have a longer rig, you’ll likely need a hose that’s closer to the 20-foot range.
Some RV owners find that it’s helpful to carry varying lengths of sewer hose. This practice allows them to make up for any discrepancies.
Grey or Black Tank Outlet Size
Outlet size is something that most modern RV owners won’t have to worry about, as newer vehicles have standardized tank outlet sizes. If you’re driving an older rig, however, you’ll need to pay attention to this. Ensure that the RV sewer house you purchase will adapt to different outlet sizes. If it doesn’t, make sure to grab a sewer hose adapter that fits your motorhome. I had to learn this the hard way when refurbishing an old Winnebago.
How much storage space do you have for your hose? You will need a place for it when not in use. Because space is often at a premium in RVs, your hose should be easy to collapse and store. Some RVs have bumper storage spaces, which is an ideal area to store standard size hoses comfortably.
If you don’t have bumper storage and space is an issue, look for a hose that compresses down for stowage. You may also want to look for a smaller hose if you’re tight on space. Make sure to store it in an area that is separate from your main living area.
Flexibility is another vital consideration when deciding on an RV sewer hose. You’ll want to find a model that can bend and fit through your rig’s curves, as well as handle tight corners. In general, the more flexible the hose, the better, as it stands less chance of breaking. More flexible hoses also allow you to drain waste material from your rig more efficiently.
Thickness is an excellent indicator of hose durability. Thicker hoses will be sturdier and will stand up to more use than thinner models. The measurement for thickness in RV sewer hoses is typically in millimeters. For those that plan to use their RV extensively, consider buying a model that is at least 23 millimeters thick. Thickness is definitely something you should not compromise on, the last thing you want is the hose breaking and waste spilling all over your campground or other surrounding area.
A hose’s ability to provide continuous flow is another vital consideration. The hose should be wide enough to accommodate waste of all sizes, which will prevent undesirable blockages. The ideal hole size for adequate flow is 4×4 inches.
Easy to Handle
Using a sewer hose to empty your black and grey water tanks is a pretty tedious process. You should look for a sewer hose kit that is quick to set up and easy to handle. Features like adapters, macerators, and cradles help out a lot. Make sure you have the necessary equipment to do the dirty work too! Gloves are a must and you should have some good hose supports to help you out too.
There are three main types of fittings for RV black water hoses:
- Slip fitting
- Bayonet hook fitting
- CAM-lock connector
Slip fittings are a bit more old school, but arguably the simplest of the locking mechanisms.
Bayonet hook fittings are the most common locking mechanism you’ll find on sewer hoses these days and they fit well with a watertight seal.
CAM-lock connector fittings are the most expensive of the types of fittings, but are as close to leak-proof as you’re going to get.
How Often Are You Using It?
Finally, what kinds of strain will you put the hose under? Are you a frequent RV user? If you’re not, a standard RV sewer hose should do the job just fine. But if you plan to spend lots of time on your rig, you’ll want to invest in a heavy-duty sewer hose. Sure, it’ll cost you a bit more, but the higher price is worth the comfort of knowing you won’t have to deal with a nasty leak.
