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 hygenic 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. 

In this video, Zoe presents our Sullage Hose features and gives some setup tips. Special thanks to Buster and Maz for use of their motorhome as backdrop and the local cars and kookaburras for background sound effects (hehe).

Which Hose Diameter Do I need?

There is no standard sullage outlet size for Caravans/RVs in Australia. Many have a barbed fitting of 25mm or 32mm ready to go, others a clamp style fitting or simply an open/threaded pipe end waiting for your attachment. Even the drain pipes themselves have different diameters depending on make and model. 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. 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 as they will carry a significantly wider range. Our 25mm hose (refers to an internal diameter) fits standard 25mm barbed fittings (referring to external diameter) from other brands. This is the same for our 32mm hose.

Important Downward attachment:

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.

Flat Out Sullage Hose Usage Tips:

1. Remove outer plug, connect to van and walk away to unspool.

2. Connect your hose to camper/van with a downward outlet to maximise flow, as a horizontal outlet could create a fold in the hose as it drops to the ground

3. Run your hose to the drain in flowing curves rather than making tight corner bends, again this will assist flow

4. Your hose is cut into 2 lengths, use the shortest length required to meet the drain, or use the joiner provided to reach further if required

C3

M3 & M4

5. At the drain, connect the drain adaptor and hook in drain to direct flow downward and reduce chances of displacing the outlet.


To Pack Away:

1. Run clean water through camper sink to flush hose.

2. Detach from camper and insert one end plug

3.Slide this end into the centre of the reel after lining up the opening of the reel with the rubber guides

4.Wind the first length of hose walking along as you go, any excess water in the hose will be forced out naturally

5. At the junction, remove the joiner and slide about 1cm of the second hose inside the end of the hose you have already wound on

6. Carefully do your next wind to ensure it does not lose grip

7. Keep winding until you reach the end

8. Remove drain adaptor and place the second end cap on protruding end of hose
