Buyers Guide For RV Sewer Hose

RV sewer hose is one of the most necessary accessories you can have for your RV. It allows you to connect your RV sewage system to portable toilet facilities and shower units, among other things. Without a proper sewer hose connecting these components, you’ll risk having an expensive mess on your hands.This guide will offer you information and tips on choosing the best RV sewer hose.

What To Consider When Choosing

In spite of the fact that they all serve the same function, not all RV sewer hoses are created equally. We’ve compiled a list of tips to help you choose the right RV sewer hose.


There are two primary considerations when settling on an appropriate length. Make sure the drain hose is long enough to reach the waste disposal unit. Distances of 15 to 20 feet are usually sufficient at most camping sites. A hose extension might be necessary on the off chance that the sewer connection is situated some distance from the pad.

Sewer hose length decisions should also take storage options into account. The RV’s square bumper is typically used for this, but if the hose is too long, you might have trouble stowing it. Some hoses can have their length cut down to facilitate more convenient storage. You can use a tote instead of a bumper.

Thickness and Durability

It’s important for an RV sewer hose to be flexible enough to reach the water source, strong enough to be pulled across the room, and resilient enough to be compressed for storage. The hose needs to be made of a durable material that can withstand being bent and twisted frequently. Rv sewer hoses thickness can range from 15 to 26 ml. A 26-ml hose, which is much less likely to burst open during use, can be purchased for the same price as a 15-ml hose, but it will be much larger and bulkier.


If you want to hook up your RV to a sewer system, the hose must be flexible enough to reach the connection no matter where you park. This is why a sewer hose that is too rigid is useless. Consider a hose that is thick enough to withstand repeated bending without snapping in half but still has enough elasticity to curve around an obstacle. A sewer connection, no matter how inconveniently positioned (under the RV, for example), can be reached with this.

Ease of Use

RV hoses have a connection like that of a bayonetn and fold up like an accordion for convenience. When not in use, the drainpipe can be folded up into a minimal size and stored in the RV’s rear bumper, thanks to its accordion-style design. No additional equipment is required to connect or disconnect the hose from the drain pipe due to the twist-and-lock fitting connections. Dropping the end of the sewer adapter into the drainpipe is usually all that’s required to connect it to the local dump.

In the event of an emergency, the user can quickly and easily stop the flow of sewage by closing the shut off valve on some models of sewer adapters, which also feature convenient handles for handling the fitting.


If you want to keep your sewer hose from getting clogged, you need to know how fast the water moves through it. How quickly water can move through the hose is dependent on the size of the hole. This means you need to find a product with a sizable enough opening that trash won’t get stuck and cause obstructions.

A 4 by 4 inch opening is a reasonable minimum size to seek out. It is expected that this sewer hose will maintain a very steady flow and cause no problems in its intended application. However, if you anticipate heavy flow, you should look for a larger version.


The accordion-style design of an RV sewer hose not only makes it malleable and adaptable to different distances, but also makes it easier to store. In most cases, a 10-foot section of sewer hose can be compressed to a 3- or 4-foot section. Because of its small profile, the RV hose can be conveniently stored in the vehicle’s bumper, a common location for such items. Drip caps, found on both ends of every sewer hose, allow the user to completely seal off the hose, preventing any odors or leaks from escaping while the hose is in use.


RV sewer hoses have fittings at both ends that allow them to be connected to the sewer drains at dump stations and the drainpipes in RVs. The RV drain is fitted with a twist-and-lock bayonet hook fitting that has four long hooklike prongs that latch onto the drainpipe to prevent leaks and loss of connection. Both a threaded screw-on and a bayonet connection are available for attaching the hose to the sewer outlet adapter.

Tank Outlet Size

Most RVs have 3-inch drainpipes. However, the drainpipe sizes on some older RVs can vary greatly. Since most newer RVs have 3-inch drainpipes, you may need an adapter to use a sewer hose with yours.


You shouldn’t skimp on a high-quality RV sewer hose. There is a risk that if you do this, the cheap models will rust or leak to the point where they are useless. You don’t want to buy one that is too cheap and ends up being a waste of money. The better option is to create and stick to a budget. Ideally, you’d be able to spend somewhere between $40 and $150. You can find high-quality RV sewer hoses for around $40, but of course, your spending should reflect your personal preferences.

Types of RV Sewer Hoses

Unlike many RV products, these do not fall into distinct categories. Because RV sewer hoses are all essentially the same, there isn’t much material for parody. Consequently, deciding on one can be a frustrating ordeal.

RV sewer hoses vary in many ways, but length is a common denominator. The standard length for a recreational vehicle sewer hose is 15 or 20 feet. If you find yourself in need of extra reach, an extension hose is available for purchase. They usually come in 10-foot increments.

For this reason, it’s important to prioritize hose length when listing requirements for your next one. It will narrow your choices considerably and make the market more manageable.

How We Chose Our Top Picks

When compiling this guide in finding the best RV waste hoses, we considered a number of factors. Important factors included adaptability and simplicity of use. Hoses that require little effort from the user during setup and breakdown to cut down on trips to the dump are the best options. Because there is a wide variety in dump station design, we prioritized models with extended reach and the ability to navigate different types of drains.

For a kit to make the cut, its fittings had to snap on and off without any additional hardware. Translucent elbow adapters were also required so that the user could see the wastewater flowing through the system. The sewer hoses we selected were thicker and made of more robust materials because of the abuse they endure. We only went with collapsible hoses because portability is essential.


What is the standard length of an RV sewer hose?

This is determined by where the RV’s drainpipe is situated. RVs and trailers with side-mounted drain pipes only need a 15-foot connection. You’ll need a 20-foot hose if your RV’s drains are located in the middle of the vehicle’s rear.

Are all RV sewer hoses universal?

Generally speaking, that is the case. All modern RVs and motor homes use drainpipes that are 3 inches in diameter, and thus require RV sewer hoses with the same diameter. An adapter is needed to connect a 3-inch RV waste hose to the drainpipe found in some older RVs.

What’s the proper way of cleaning an RV sewer hose?

A freshwater spigot can be found at the majority of RV dump stations. The hose can be flushed out by connecting it to a spigot and running clean water through it. In general, it’s best to empty the black tank first, followed by the gray. As soon as the black water tank is empty, you can use the gray water tank to flush the hose with soap and water.

How do I store my sewer hose?

If your rig does not have a dedicated tube for storing the wastewater hose, you may find it difficult to keep it on hand. It’s important to separate the filthy waste hose from the rest of the belongings in your RV. The good news is that RV sewer hose storage options are not only accessible, but also low-cost.

Most people use a large plastic container with a lid to store their black and gray water drain hose. Place this box in a secure outdoor storage area or the back of your truck.

How frequently must I replace my RV sewer hose?

It’s recommended to replace a sewer hose every three years to prevent leaks and tears. Replacement every two years is recommended for full-time RVers.

How many sewer hoses do I need for my RV?

In reality, the amount of available storage can affect this answer. Most RVs only require a single sewer hose, but there are hoses that can simultaneously drain both the black and gray water tanks. In addition, if your sewer hose breaks while you’re boondocking, you’ll be glad you brought a spare.

Can I connect two RV drain hoses?

Yes. This is the intended application for some toolkits. For safety reasons, a bayonet fitting should be used to connect both hoses.

How big is the typical RV sewer hose?

Generally, a 3-inch hose is used as a drain in a recreational vehicle.

Final Thoughts

Dumping waste tanks is one of the dirtiest tasks of RVing. There is nothing worse than cleaning up a spill of black water because your waste hose broke. If you want to avoid an unpleasant smell at the dump station, make sure your RV is equipped with a high-quality sewer hose kit.

The best RV black water hose has sturdy build quality and leak-resistant connections, making a rather unpleasant job a little more bearable. You can eliminate, or at least significantly lessen, the likelihood of a dumping accident caused by shoddy building or materials. When shopping for a sewer hose for your RV, don’t skimp. Your future self will appreciate it.
