RV Sewer Hoses

Select a hose length that reaches comfortably from your RV outlet to the dump station—common lengths are 10–20 feet; measure the run including climbs and turns. Most RVs use a 3- or 4-inch diameter fitting, so confirm your RV and dump station connection before buying or use an adapter if needed

Look for heavy-duty, flexible materials like reinforced PVC or multi-ply polyethylene with ribbed ends and secure bayonet or threaded fittings; reinforced designs resist kinking and crushing while remaining flexible in cold temperatures

Consider a sewer hose support to maintain downhill flow, a secure cap or elbow for the RV outlet, a storage bag or case to keep the hose clean, and adapters or extension couplers if your fittings differ or you need extra length

Rinse the hose with clear water after each dump, use a hose-cleaning nozzle and a biodegradable, enzyme-based cleaner periodically, and store the hose dry and sealed in a dedicated bag to limit odors and bacterial growth

Consider collapsible or segmented hoses for compact storage, as well as the weight and whether the hose fits your RV’s holding tank compartment or a separate storage tote; durable storage cases help prevent contamination of other gear

Prices typically range from budget options under $50 for basic hoses to (price varies)+ for heavy-duty kits and accessories, with many well-rated mid-range options around the category average

Universal adapters can reliably bridge different connection sizes and types if they are rated for sewage use and create a secure, leak-free seal; always verify compatibility and use hose clamps or lock rings when recommended
