While RV sewer accessories might not get you pumped for RVing, they are absolutely necessary to avoid smells, accidents, and cleanliness. Personally, I was really grossed out about the idea of RV sewer when we were thinking about jumping into RV life, but now I’m weirdly obsessed with it. Ensuring our tanks are clean, smell-free, and thoroughly rinsed is oddly satisfying.

To make sure that your tanks are squeaky clean and the dumping process is a breeze, I’ve compiled the below list of my favorite RV sewer accessories. All of these tools and products will make sure you don’t have any nasty accidents while dumping and your black tank stays clean and smell free!

Sound good? Let’s dive in.

RV Sewer Accessories for Easy Dumping

Sewer Hose

Obviously, you will need a hose to connect to your RV so you can dump your tanks. The hose below is from a company called Camco. They create tons of RV supplies that hold up well over time. We’ve had our hose since we hit the road in 2017 and it’s been great.

Camco RhinoFLEX 20' Camper/RV Sewer Hose Kit - Includes 4-in-1 Adapter, Clear Elbow, & Caps - Connects to 3″ Slip & 3″, 3 1/2″, 4″ NPT Threaded Sewer Connections (39742)

Sewer Hose Support

While this RV sewer accessory isn’t necessary, it’s very convenient. It is higher on one end than the other so when you place your sewer hose in it, there is now a natural flow with the help of gravity. We wouldn’t RV without ours!

  • PROTECTS & SUPPORTS YOUR RV SEWER HOSE: This sewer hose support for RV campers lifts and guides your sewer hose to help...
  • COMPATIBILITY: It fits up to a 20-foot RV waste hose and works with all 3-inch diameter hoses.

Sewer Hose Extension

Trust me when I say you will end up needing a sewer hose extension at some point! Every RV park is different when it comes to the placement of their sewer connection and boy is it not fun to find out your hose doesn’t reach. We actually have our main hose and then three additional extension. And yes, we’ve used them all at once a handful of times.

Camco RhinoFLEX Heavy Duty 10ft RV Sewer Hose Extension Kit with Swivel Fitting - Extends Your Sewer Hose to Fit Your Needs (39764)
  • Kit Includes: 10-foot Rhino FLEX extension with (1) pre-attached lug and bayonet fitting
  • Compatibility: Compatible with any sewer hose that has a bayonet fitting

Sewer Hose Storage Caps

These caps are great for keeping things dry between camping trips. They attach to each end of your sewer hose and create an odor tight connection. We love them because they prevent any dripping from our sewer hose into our storage pipe.

  • RV Sewer Hose Storage Caps (Eng/Fr) (1 Bayonet, 4N1 Cap)2Pk
  • RV Sewer Hose Storage Caps (Eng/Fr) (1 Bayonet, 4N1 Cap)2Pk

Sewer Hose Replacement Gasket

It’s always a good idea to have a few of these gaskets around! If by chance you notice your sewer hose leaking at the connections, you can quickly replace the gasket and be good to go. You’ll want to have a few of these in your RV sewer accessory arsenal.

Sewer Hose Seal

While it would be awesome if all RV parks used the same standard sizing for their sewer connections, they don’t. There are typically three sizes for sewer hose connections, however, you will still find a weird one here and there. That’s when this RV sewer accessory comes in to play. It’s great to have so there isn’t any leakage if your connection is the wrong size.

Camco 39312 Sewer Hose Seal - 4" x 3"
  • Connects directly on RV sewer hose for an odor proof connection to dump station
  • Made in the USA

Clear Extension

This RV sewer accessory looks pretty boring but it has saved us from frustration a few times. This accessory adds three inches of height to your sewer connection. This is important because some RV parks have really recessed sewer connections and even though you might be able to screw your 4-in-1 adapter in, your hose won’t make the connection. This tool fixes that problem and allows for a secure connection.

Camco 39735 4-n-1 Sewer Extension for Recessed Dump Station
  • Extends the attachment height of your 4-in-1 adapter 3" for recessed dump stations
  • Fits in between Camco's 4-in-1 adapter and elbow

Clear Elbow Fitting

Now, you might think it gross to have a clear fitting but seriously, you want to see what’s coming out of your tank. More specifically, you want to see when your flushes are running clear water; that’s how you know your tanks are clean. If you can’t see what’s coming out of your tanks, you can’t guarantee you’re getting a good cleaning. While it might not be the most glamorous RV sewer accessory, it’s absolutely necessary.

Camco 39736, RhinoFlex Clear RV Sewer Hose Elbow with 4-in-1 Adapter | Features a 360-Degree Fitting Rotation and Built-in Gasket for Odor-Tight Protection | Fits 4 Sizes of Dump Station Inlets
  • Securely Connects: RV sewer elbow adapter fits securely into dump station connection
  • Fits Four sizes of Dump Station Inlets: fits securely into four sizes of dump station inlets— 4-inch NPT, 3. 5-inch...

Twist On Waste Valve

This is one of our favorite RV sewer accessories. You can permanently place this at the end of the sewer connection on your RV. It helps prevent any leakage that might happen after you’re done dumping your tanks. Trust me, there is nothing more disgusting than opening your sewer connection to hook up your hose and have liquid come out. This accessory stops that!

  • No more mess with an old valve problem.Fit Type: Universal Fit
  • Twists onto your current waste valve

Sewer Tank Rinser

This is the perfect tool for those rigs where the RV sewer connection is a straight shot to their black tank. You can use this connection to not only dump your tanks, but then spray water back up it to rinse your tank as well.

Waste Master Sewer Hose

If you want to step your sewer game up, the Waste Master is for you. This sewer hose connects permanently to your RV (so there is an installation process) and features a 90-degree discharge port that is easy to fit and secure into any sewage inlet. The nozzle has an easy-grip handle, an integrated shut-off valve, and a clear viewport that allows you to see when the tanks are empty or water is running clear.

Black Tank Rinsing Hose

For those of you that have a black tank rinse built into your RV, you need to have a separate hose for that. In other words, do not use your fresh water hose to rinse your black tank! While it might just seem like only water goes in both of those connections, there is a risk of backflow, which would contaminate your fresh water hose. Just imagine if you rinsed your black water tank, unknowingly had backflow, then the next time you used the same hose for your freshwater connection you would be getting poo particles in there! Barf! So I repeat, do not use your fresh water hose to rinse your black tank!

Sewer Wrench

This tool is so handy! Eventually, you will run into a sewer cap at a campground that is impossible to open. We’ve also found ourselves in situations where we are packing up camp and cannot unscrew our adapter. Both of these circumstances are irritating and time-wasting. This accessory not only helps unscrew caps but can be flipped over to help unscrew a stuck adapter. It’s a great little tool to have in your arsenal!

360 Siphon Roof Vent

We had issues with smells about a year into RVing and could not figure out where it was coming from. We changed our air admittance valves under all the sinks, deep cleaned our tanks multiple times, and even checked our ACs for possible dead critters. Nothing helped! Finally, we were told to change our roof vent for the black and grey tanks to the 360 Siphon Roof Vent, and voilà, no more smells since!

  1. Hi Rae,
    If you really want to simplify the process of dumping stop by our shop in Hollister Ca meet the gang and talk Waste Management! Dumping holding tanks can(and is with our system) be as simple as putting gas in your vehicle. You get what you pay for and we are more expensive than the industry average but worth every penny!

  2. Rae, I have used the Waste Master Sewer Hose for years. It’s expensive but well worth it.
