25mm X 20M Sullage HoseThe Nylex Sullage Hose has been specifically designed for use in caravans, pop tops and camper trailers. The Sullage Hose connects to your waste water outlet, with the internal smooth surface designed for greywater usage ensuring small food particles from the kitchen sink won't get stuck within the hose walls. The sullage hose is purple to indicate that water from this outlet is not safe to drink, especially useful when on holidays with the kids.
