Valterra RV City-Water Inlets: Flush, Recessed & Thread Types

A standalone RV city-water inlet connects an exterior drinking-water hose to the RV's pressurized freshwater plumbing. When replacing one, check more than the exterior colour: flush versus recessed mounting, male versus female pipe threads, and the actual wall opening all matter. The Valterra inlets below are separate from larger hatches that combine city water with a gravity tank-fill port.

What changes between these versions?

Flush mounting versus recessed mounting

The flush-mount models use an inlet flange positioned at the RV exterior. The A01-0176LF and A01-0177LF use recessed arrangements. Do not assume the wall opening or depth is the same. The flush models listed with a 2¾-inch flange still require the original wall cutout and mounting points to be checked before ordering.

Male versus female threads

The ½-inch male pipe-thread fitting on A01-0170LF connects to a matching female plumbing fitting. A01-0171LF uses a female pipe-thread connection and requires a corresponding male fitting. These two white flush-mount inlets are therefore not interchangeable without confirming the plumbing behind the wall. The same check applies to black, aluminum-finish and recessed versions.

Finish and original part number

Several inlets have similar shapes and connection sizes but different finishes. A01-0172LF uses an aluminum finish rather than white; A01-0177LF is colonial white rather than the standard white A01-0176LF. Matching the exact existing manufacturer number is the best starting point when replacing a fitting.

A01-0171LF — White flush-mount female-thread inlet

White 2¾-inch flange with a ½-inch female pipe-thread connection. The internal connection differs from male-thread A01-0170LF.

A01-0172LF — Aluminum-finish flush inlet

A flush-mount aluminum-finish inlet with brass check valve and female pipe-thread connection. Match the finish, fitting and mounting location rather than choosing the white inlet by appearance.

A01-0176LF — White recessed inlet

Recessed white city-water inlet with a brass check valve and a female plumbing connection. Check recess depth and wall opening; a flush fitting is not automatically interchangeable.

A01-0177LF — Colonial-white recessed inlet

Colonial-white recessed city-water inlet with brass check valve and female pipe-thread connection. Its color differs from the standard white A01-0176LF; confirm the wall opening and depth.

How a city-water inlet fits into the system

This is a general connection overview, not a piping diagram for a specific RV. A city-water inlet is not the gravity-fill opening for the fresh-water storage tank. The inlet check valve does not replace any required backflow protection or water-pressure regulation.

Replacement checklist

1. Identify the existing part. Record the manufacturer number and check whether the current inlet is flush or recessed.
2. Inspect the RV-side connection. Verify whether the existing pipe fitting needs male or female ½-inch threads, and check available space behind the wall.
3. Measure the opening. Check the actual wall cutout, flange coverage, screw locations and recess depth. Do not cut the RV wall using a nominal flange diameter alone.
4. Match the finish. Choose black, white, colonial white or aluminum finish by the exact part variant.
5. Install and test carefully. Isolate the water supply, use the correct pipe sealing method and exterior wall sealant, then check for leaks under appropriate pressure.
