The Flat Out Sullage Hose (Grey Water Hose for Caravan & RV)
Especially designed for caravans, campers and motorhomes—suffer your sullage sulks no more!
Sullage hoses are usually large, smelly, brittle in cold weather and difficult to store tidily. We’ve heard storage stories (of other brand hoses) ranging from coiling in a garbage bin in the van shower, to winding around the gas bottle on the draw bar. Our sullage solution is the most compact and easiest to use available in today's market.
Made from heavy duty elastomer, our hoses roll flat onto our Multi-Reels and automatically expand when unspooled to offer high flow grey water disposal. With a flexible smooth finish, they are durable in harsh conditions and collection of debris inside the hose is inhibited. End plugs ensure no leakage or smell when stored.
As the hose is stored without air inside, any microbes remaining will go to sleep rather than reproduce through storage periods, making it the most hygienic sullage hose solution.
Working with a flat hose that is gravity fed, it is important to connect to drain point with the shortest length of hose you have if you wish to achieve maximum flow. All our sullage hoses come in cut lengths with a joiner provided for when the full distance is needed.

A 3m length of Flat Out sullage hose in 25mm or 32mm to be used as an extension of your existing hose or a replacement of a lost or damaged length.
If adding this item as an extension, also add a straight joiner (S5/S12). If this is a replacement you won't need the additional joiner.
This ratchet clamp can be used to hold your flexible sullage hose onto fittings in a tighter manner. The hose itself will slide over fittings and grip, however if you are finding you wish for a tighter connection, add a clamp such as this one.
Place the clamp around the hose and pipe and press the sides of the clamp together to hold the ring in place. When you wish to release the clamp push one tab away while pulling the other towards you (in the direction of the pipe) and the grooves will slide off one-another.

If you have a horizontal sullage outlet you can cut a short length of hose and use it to attach this elbow to your outlet creating a downward flow to attach your main hose. You will probably find better right angled parts from an irrigation store for attaching to your van (threaded so you can screw them on), but the option is here as a back-up if needed.
PVC joiner barbed at both ends used to connect 2 lengths of Flat Out sullage hose togehter.
One is provided with your purchase of any Sullage Hose on Multi-Reel product to achieve the full 6m or 9m length of hose. If you wish to cut your hose into shorter lengths or carry an extension hose, you will need an extra joiner to achieve full length.
These are standard irrigation fittings, so they are interchangeable if you wish to collect them from your local hardware/irrigation store.
Used to hook your 25mm or 32mm Flat Out sullage hose into a drain pipe. One end is barbed for you to insert into the end of your sullage hose, the other end is elongated so that it hooks into the drain better.
The reason you need a drain adaptor is if you were to poke your flat hose into a pipe, you would force a kink, and that will restrict flow. This drain adaptor allows the water to freely change direction.
One of these units is supplied with with Flat Out Sullage Hose on Multi-Reel units, this is offered here as a spare or replacement.
Barbed adaptor: one end 25mm the other 32mm. Contains short length of 32mm hose to allow easy connection to a 32mm waste outlet for a 25mm hose.
This item would be useful if you are interested in our most compact sullage model C3 (6m 25mm hose) yet your outlet is 32mm OD. We only recommend downscaling to a 25mm hose if you have a holding tank to buffer high flow times. Otherwise we suggest you matcvh your hose to your outlet and use the M4 allowing maximum flow rates.

Black Vs Grey Multi-Reels
In 2023 we introduced a new range of Sullage hoses on Matte Black Multi-reels. These new Multi-reels are made from over 95% recycled industrial plastics, with no compromise on structural integrity. There is no difference in the hoses for each unit. We have now discontinued production of Flat Out Sullage hoses on Grey Multi-Reels, the lower price for those units is available until sold out.
How to choose the right sullage hose for you
"Which one should I get?" is a question we are often asked. Firstly, you do not need to select a hose based on the outlet on your van.
There is no standard sullage outlet size for Caravans/RVs in Australia. However this is no cause for concern, as fittings and conversion parts are easy to come-by.
We suggest you select a hose based on your space, length and flow requirements and then acquire fittings accordingly. See the decision quiz that follows for how we help people choose.
Regarding fittings, we stock a few helpful attachments yet if none of those qualify, we suggest you talk to your local pumps/irrigation or caravan parts specialist. They will carry a significantly wider range, you simply need to ensure your outlet finishes on a downward pointing barbed fitting of the same size as the hose you choose (ie 25mm or 32mm).

Important Downward Connection
Please ensure that you connect our hose to a downward outlet, or the hose will fold before water flows into it and fail. If you have a horizontal outlet on your camper, you can add a second ‘drain adaptor’ to your purchase that will act as a downward connection adaptor.

When Zoe was at a caravan show in canberra last year she met Rob as he came across our stand. He sang praises of his sullage hose and we asked if he wouldn't mind telling you about it. The result is the video you see here.
Glen is a Flat Out International fan and shares his tips with fellow travellers for an easy grey water collection tank. He uses the same fitting (that he made himself) to easily connect his flat sullage hose at the correct angle.
