View W01-5315Valterra Heated RV Water Hoses: 15, 25 & 50 ft Freeze Protection
A heated RV drinking-water hose helps prevent water inside the supply hose from freezing during cold-weather camping. Valterra offers several blue heated hoses with different lengths, inside diameters and temperature ratings. The hose heater protects the hose—not the campground faucet or RV plumbing beyond its ends. Compare the exact models below before choosing one.

Which hose is right for your campsite?
The W01-5315, W01-5325 and W01-5350 use 1/2-inch hose, with a listed freeze-protection rating down to -5°F (-21°C). Their respective lengths are 15, 25 and 50 feet. The W01-6325 and W01-6350 use 5/8-inch hose and are rated down to -20°F (-29°C), in 25- and 50-foot versions. These are manufacturer ratings, not guarantees that every installation will remain unfrozen: end connections and upstream/downstream pipes require their own protection.
Measure the route from the water tap to the RV's city-water inlet, including room for a pressure regulator, filter and bends. Avoid stretching the hose or routing it where a vehicle, step or door may pinch it.

View W01-6350How the heated hose fits into your hookup
Campground tap
A separate freeze-protection plan is needed for the exposed supply fixture.
Heated hose
Self-regulating heat runs along the hose and is powered from a suitable outlet.
RV inlet
Use the insulated cuff and protect any exposed inlet fittings separately.
Interior plumbing
The RV's own freshwater system still needs suitable winter protection.
This is an installation overview, not a vehicle-specific plumbing diagram. The self-regulating heating system operates without a separate thermostat. The 1/2-inch models list a six-foot cord with a lighted plug and zippered insulation cuffs; the 5/8-inch models also use insulated end cuffs.
Safe setup and care
- Confirm water and electrical connections. Use a potable-water source, matching hose fittings and an outdoor GFCI-protected 120V outlet. Keep electrical connections dry.
- Connect and flush the hose before applying power. Follow the Valterra instructions, confirm flow and check all fittings for leaks.
- Do not use an extension cord. Use the heater's own supplied power cord, with its outlet and connection protected from water.
- Protect the ends separately. Use the zippered insulation cuffs but remember the heating system does not keep a campground tap, regulator, RV inlet or exposed internal line from freezing.
- Keep the hose unpinched. Avoid sharp bends, kinks, traffic areas and mechanical strain on the end connections.
- Unplug, drain and coil when storing. Follow the manufacturer's maintenance and storage instructions.
Manufacturer installation reference
Valterra's product manuals and instructions provide directions for powered freshwater hoses. Check the manual included with the exact hose before winter use, especially the electrical connection requirements and precautions for end fittings.
