RV Sewer Hoses Reviews
Camco 20′ RhinoFLEX
This model has 4 inches in diameter and it can withstand the load for a long period since it features 23 mils of polyolefin. In addition, it’s enhanced with steel wire. This RV drain hose is suitable for removing hot liquids allowing taking hot showers without worrying of damages or stagnations.
Each of its ends has the same RV sewer hose fittings on the edges to joint two of them together with a view to elongate the unit. Those fittings and the Camco 20′ RhinoFLEX itself make a tough bayonet joint between each other with 4 prongs for a secure fit. This model has Vaseline on the edges to facilitate sealing the connections to the unit.
The unit comes with the translucent elbow that’s why sometimes it is hard to see when the line is really clean. The product also has a removable 4-in-1 adapter to be stored in 4-inch square bumpers.
This unit stays tightly where it has been put without stretching and writhing. It collapses with a snap and stays that way until being pulled out to length again. It’s rigid and allows forming long radius bends to help keep everything flowing well. Its far tubing and all the connectors are sturdy enough to prevent leaks.
Pros
- It doesn’t slack so there is no need to support it.
- This sewer hoses disconnect from the coupler and adjusted very easy.
Cons
- Upon opening, there is a lot of mess that takes time to wipe it out before use.
Titan 20′ Thetford 17902
This RV sewer hose kit has a length that is enough for long connections and it’s completed with a revolved the 5-in-1 sewer adapter with exclusive handle and 2 caps for edges of the unit. The unit is very sturdy with the leak-proof bayonet connections and it’s rippled inside. Since the hose membrane and the internal structure are thick, it expands only about twice it’s length (the majority of other products are able to expand beyond 4 times). For the same reason, it might be compressed not enough to fit into some plastic hose holders.
This model is hooked up easily and doesn’t leak at all, even when connecting it to another hose to make it extend. The fittings on this hose might not fit in the rear bumper of the fifth wheel. In this case, a 5-in-1 adapter should be removed. Besides, it’s possible to cut the adapter to fit in the sewage line. If making this unit suitable for the 2-inch tent trailer, a more significant modification is required.
Pros
- The multi-purpose pipe-connection end covers all the standard pipe sizes and it has a solid build.
- The handle allows working with the connection without getting hands close to the nastiness.
Cons
- It doesn’t have screw-on bung caps so when stowing it in the bumper, it shoots the cap off and sprays a hand.
Valterra Black 20 Ft Kit D04-0275
This RV dump hose is remarkable for its UV stabilized poly construction design that successfully prevents springing any leak and spilling water out. The unit features 23-mil thickness that makes it more prone to holes and scratches since the thicker are the hose’s walls the more durable they are. It’s also noted for its incredible flexibility and the ability to hold shape even after installation.
The hose fits in a 4-inch bumper for storage but the flange won’t fit in it that’s why it’s necessary to get a 5-inch round cylinder to compensate for this shortcoming. To ensure full connection/disconnection and to make it super-easy, it’s better to add silicone lube to the rubber seal. Note that it’s impossible to remove fittings on either end in order to shorten the hose.
The kit contains two 10-inch sections of the sewer line. Each section has its own connections attached to use them separately or snapped together. It is even possible to connect more than two 10-feet sections together. However, the longer the hose is, the harder the draining is without picking up the hose.
Being 20-feet long, it stays in the exact position when it’s stretched and no wiggling are noted when dumping the tanks. Besides, it’s possible to see the liquid flowing through the clear elbow connector that’s attached to the PVC sewer pipe when dumping.
Pros
- It’s possible to attach the unit to a barker tote.
- As the manufacturer claims, it can be used all year round and withstands both frost and heat.
Cons
- It’s harder to rinse comparing to some other hoses.
Lippert 359724 Waste Master 20’
When wondering where to get the best sewer hose for RV, think of the Lippert 359724 Waste Master 20’ with a convenient nozzle that comes with a handle to facilitate the unit’s control. This model is also remarkable for its 90-degree discharge port to hook it up to any sewage inlet.
The system comes with caps to cover the ends. It prevents leaking out waste products into the bin if carrying the sewer hose in. The clear pipe next to the valve permits to see when clear water starts coming through.
The unit is designed to be compatible with the Waste Master CAM Lock system. It features a CAM lock male connector on the entry end while the RV has a permanently mounted CAM lock receiver for connection to the hose. Waste Master allows a back-to-bayonet fitting using this hose with the standard fittings on RVs or tote tanks.
The hose is rather massive that’s why even the 5-gallon bucket might be not enough to store it. However, a manufacturer produced dedicated Gen2 storage.
Pros
- The unit comes with smooth internal piping with the wire supported outside that makes flow through the pipe flawless.
- This product stretches and collapses easily.
Cons
- The rubber ring on the discharge side of the hose slides off easily and that’s why it’s necessary to pull the ring out separately when pulling the discharge end out of the dump station (gloves are highly recommended for that purpose).
Camco 39631-A 20′
The internal diameter of this RV sewer hose is 2.75 inches and it fits the standard RV sewer connections. It’s a basic product with the bayonet fitting that is only on one “female” side. The “male” one should be bought separately to put it on the other end.
The hose is made of 15-mils brown HTS vinyl and it’s designed only for the occasional or seasonal use – for summer weekend trips, for example. It features durable construction since it contains 25% more vinyl than other heavy-duty sewer products.
The unit can be used as the car A/C vent extender for babies in rear-facing car seats. Just hook it onto a canning funnel fastened to the vent. The plastic is easy to pierce (for the zip ties) but doesn’t easily rip. So, it will last in the car for a long time.
The unit has no connectors in the box. However, when buying them for the ends, they are put on hassle-free. Besides, if replacing an old hose with the Camco 39631-A 20′, it’s possible to use those old unit’s connectors. Note that this hose doesn’t screw down the pipe, but its’ a “reverse-threaded” model meaning the usage of the hose clamps that are rather sharp and stow back into its container not easily.
Pros
- The unit is easy to store since it compresses up to 32 inches and it fits even the 4-inch rear bumper storage.
Cons
- It requires many efforts to stretch it.
Prest-O-Fit 1-0067 10′

This model is lightweight enough to store and carry when needed without any efforts. It’s also easy to use – just extend it out as far as it’s necessary, hook it up, and remove it fast after the job is done.
This model is made of the long-lasting, heavy-duty polyolefin (that is able to protect items from ultraviolet rays) with 23-mils vinyl and it features steel-wire reinforcement, so, no leaks are ensured. One can store this unit in the RV bumper compartment. It’s a thick walled product and it retracts to about 40% of full length for storage.
Pros
- It’s compatible with the other manufacturers’ hoses (all the parameters still should be considered) that allows connecting it to an existing hose and escape spending money on 2 units.
- It retains its shape completely after its bending.
Cons
- Too short to be used in the singular.
Clean Dump (CDH-10) 10′
This heavy-duty and UV-resistant model is developed for the FloJet pump. The unit has a 1-inch ID and it is rigid enough. The hose allows emptying any black-water holding tank fast and the pump doesn’t stop in the process.
It’s recommended to get the dedicated adapter to increase the flow rate by 40% since its’ not in the box. Still, it comes with male and female ends for flawless connection and allows extending a macerator hose of any type. Besides, it’s possible to connect drip proof shut off valve. Such sewer cap rotates for a perfect connection to any sewer receptacle.

Pros
- It’s completely transparent to see what’s going through the hose and to prevent running the pump dry.
- It can pump uphill.
Cons
- More length would be great since it’s necessary to get one more 10-feet unit to make it reach the sewage equipment.
Buyer’s Guide
Sewer Hose Connection – How to Make It Correctly
How to hook up RV sewer hose to the main sewers and attach it to a camper? First, it should be mentioned that it’s highly recommended to put the gloves on since it’s about literally dirty work. Then, pull the hose out of the bumper compartment and take the best RV sewer hose support to prevent possible damages, owing to the friction with the ground.
- Take a hose and drop it down in the drain at your park.
- Remove the cap from the pipe of a trailer.
- Put a hose down inside the drain.
- Make sure that all the valves on the hose are closed.
Make a connection between the sewer hose, the dump station opening, and the tank. Take two little “ears”, slide the hose over and lock the “ears” to the coupling. The hose is already hooked up to a trailer.
- Open the black tank hose valve.
- Open the gray tank hose valve.
It’s crucial to let the clean water from shower rinse the hose after the dirty water from the toilet will pass through the hose. It’s also helpful to use clear sewer adapter to know the moment the tanks have finished emptying.
- Close the valves after draining.
- Disconnect the unit – just twist the lock, pull the hose off, and reinstall the cap.
Note that the cap should always cover the pipe when traveling down the road to prevent from acquiring foreign particles.
Then, it’s time for cleaning through flushing it out and backwashing the hose. It’s possible to use enzyme treatments to ensure perfect cleaning. Besides, it would be helpful to check the tank to remove waste completely. Otherwise, it might contaminate a hose. When everything is done, compress a unit and store it in a suitable compartment.
It is not recommended to empty the black tanks if they’re not full (less than 2/3 of their volume). However, if required, add water or ¼ cup of dishwashing detergent.
How to Save a Sewer Hose from Cold?
Since cold weather can damage even the most durable units, the question arises on “how to keep RV sewer hose from freezing?” Basically, there are two things one should do to protect a hose from low temperatures and avoid its cracking. The first thing to do is not leave a hose on the frost but hide it in the bumper compartment at once after it handles the job.
The second thing is also crucial. It’s necessary to heat and insulate a sewer hose. Water pipe heat cable is usually used to run it along the length of a sewer hose in order to heat it. To insulate the unit, the pipe wrap insulation made of foil-backed fiberglass is required. When a hose is wrapped, it necessary to fix insulation with duct tape to save its insulating properties.
The valves are at a huge risk and should be also freeze-proof. How to solve the issue? Take a heavy-duty aluminum foil to wrap the trailers pipe where the valve is attached. Then, use a heat cable as the second layer for wrapping it around a pipe and fix it with a PVC tape.
Consider making no more than 12 inches of space between each wrap. The next step is to cover a heat cable with fiberglass insulation. Don’t forget to leave the cable’s small control panel outside the insulation. The last thing to do is to wrap a foiled tape around the insulated pipe.
Everything is ready but if the pipe’s “design” looks too sparkly, it’s possible to wrap black duct tape around it in order to make a pipe not so flashy.
If neglecting the rules and allowing a sewer hose freezing, the water will accumulate slowly in the bottom of a hose and it will freeze. The next layer will come down and will freeze on top of the previous one.
Which Length to Choose When Buying a Sewer Hose?
There are 10, 15, and 20-feet units on the market. How long should RV sewer hose be to provide proper fulfillment of their functions? The 10-feet units are too short in the majority of cases since they can’t reach a sewage dump outlet. However, they come in handy when attaching it to another 10-feet hose as an addition to the existing hose or a replacement for an old one.
