Customer reviews for 25mm Flat Out Sullage Hose: 6m on Compact Multi-Reel

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 industrial elastomer, our hoses roll flat onto our Multi-Reels and automatically expand when unspooled and water is fed through them, offering tidy 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 more hygienic than any other 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. 

Our new Matte Black Multi-Reels are made from at least 95% recycled industrial polypropylene, without compromise on toughness. As the hose is designed to last, you can have the one product last you many many years rather than the constant replacement cycle that is needed for brittle or low hygiene sullage hoses. This makes Flat Out Sullage Hoses also the most environmentally responsible choice available.
