RV Freshwater Hoses & Fittings

Choose a hose labeled food-grade or potable water safe, check diameter (typically 1/2" or 3/4") to match your RV fittings, and consider length, flexibility, and UV resistance based on hookup location and storage needs

Common materials are PVC, reinforced vinyl, and drinking-water-safe rubber; brass or stainless-steel threaded fittings resist corrosion better than plated zinc, and quick-connect or threaded garden-style fittings should match your RV inlet and spigot types

Rinse and flush a new hose before first use, store it clean and dry off the ground, avoid leaving hose sections in direct sunlight for long periods, and sanitize periodically with a diluted bleach solution or an RV-specific sanitizing product following manufacturer guidelines

Choose the correct inside diameter to maintain adequate flow; 3/4" provides higher flow than 1/2"; check the hose's working pressure rating for compatibility with campground water systems, and ensure fittings are rated for potable water

Hoses can degrade from UV exposure, kinking, freezing, and chemical exposure; lifespan varies widely by material and use but planning to replace hoses every few years or sooner if you see cracks, soft spots, or discoloration is prudent

Yes if the hose’s working pressure rating exceeds the system pressure; for onboard pumps, check fittings and diameter compatibility and use hoses rated for potable water to avoid contamination

Freshwater hoses and fittings commonly range from budget options under $50 to higher-end items over $100; pricier products typically offer thicker reinforcement, brass or stainless fittings, longer lengths, improved UV and temperature resistance, and food-grade certifications
