Valterra RV Fresh-Water Tank Fillers: Quick Fill vs Secure-Fill

When filling an RV's fresh-water tank through its exterior gravity-fill hatch, a loose garden hose can be awkward to hold and may splash or back up at the opening. Valterra offers two different tank-filling attachments: a slip-in Quick Fill pigtail without a shut-off and a locking Secure-Fill tool with its own valve. They are accessories for filling the tank, not replacements for the hatch or a pressurized city-water inlet.

Which filling style works for your RV?

A01-0030VP: easy slip-in pigtail

Choose this style when you want a removable tube that goes into an existing gravity-fill opening. Valterra designed it to reduce water backing up as you fill the tank. Since this model does not have a shut-off valve, you control the water at the hose supply. Confirm the filler tube can seat properly in your particular hatch opening.

A01-0035VP: Secure-Fill with locking attachment

This version attaches to a garden hose and twists into a compatible fresh-water fill spout. The lock-on design holds the tool in place, and the built-in on/off valve controls the flow at the connection. Valterra describes the tool as hands-free, but it must not be left filling unattended. Turn the water off as soon as the tank is full, then remove the tool.

Before filling the tank

1. Find the RV's gravity-fill opening, not its separate pressurized city-water connection.
2. Check that the filler matches the fill-spout geometry and the garden-hose connection.
3. Start the supply carefully, monitor the tank level and keep the vent path unobstructed.
4. Turn off the water promptly when full; do not rely on a hands-free holder to stop an overflow.

If the exterior opening itself is damaged, see the Valterra gravity-fill and city-water hatch guide to compare complete inlet assemblies.
