Valterra RV Drinking-Water Hoses: 25 & 50 ft, 1/2 vs 5/8 Inch

For an RV drinking-water hookup, choose a hose by the distance to the water supply, its inside diameter and the pressure it is rated to withstand. Valterra offers these non-heated AquaFRESH hoses in white and blue, with 25- and 50-foot lengths and 1/2-inch or 5/8-inch inside diameters. The working-pressure rating changes with the diameter, so the exact part number is worth checking.

Valterra drinking-water hose comparison

What the diameter and PSI ratings mean

The 1/2-inch hoses in this range are rated at 160 PSI working pressure, while the 5/8-inch versions are rated at 120 PSI. A 5/8-inch hose has a larger internal passage, which can help reduce restriction in some setups, but actual flow depends on the supply, hose length, regulator and plumbing. The hose's working-pressure rating is not the pressure you should supply to the RV. Always follow the RV manufacturer's maximum inlet-pressure limit and use an appropriate regulator.

25-foot or 50-foot hose?

Choose a 25-foot hose if it reaches the campground supply with adequate slack and without straining the fittings. A 50-foot hose offers more reach but takes additional storage space and can introduce more restriction. Measure the real path from the water tap to the RV's city-water inlet, including the regulator, filter and any bends.

White and blue versions

Both colour groups are intended for drinking-water use and Valterra lists NSF materials and an easy-to-use hose gripper. The blue versions listed here include pre-installed hose savers at both ends. Choose colour, diameter and length by the exact part number rather than assuming the same colour always means the same specifications.

Typical RV city-water connection

The following describes the functions of a typical campground hookup; it is not a plumbing diagram for any particular RV.

Before ordering and connecting

1. Measure the distance and routing from the water tap to the RV, allowing for the inlet location and any accessories.
2. Choose a 1/2-inch or 5/8-inch inside diameter, then match the exact length and MPN.
3. Confirm the hose-end fittings, seals and available clearance for a filter or pressure regulator.
4. Never treat the hose's 120- or 160-PSI rating as a recommended operating pressure for the RV.
5. Flush and care for the potable-water hose according to its instructions, keep its fittings clean and store it away from sanitation-rinsing equipment.
