Valterra Black Gravity Water Inlet Hatch A01-2004BK Fresh Water Fill

This Valterra gravity water inlet hatch is designed for fresh water holding tank fill applications. It combines a lockable hatch, UV-stabilized plastic construction, and vented gravity fill design in one replacement assembly.

Part Number: VAL2004BKBU Black Locking Hatch Gravity Fill + City Hookup

Overview

This Valterra gravity water inlet hatch is a practical replacement solution for RV and trailer fresh water systems using a gravity fill setup. It is designed for applications where the wall cutout, outer dimensions, and connection sizes match, and it features a lockable door, built-in venting, and a pressure-side connection with integrated check valve.

R&P Service Insight

Water inlet hatches often need replacement when the door cracks, the lock fails, or the original assembly no longer seals or fills correctly. The most important checks are the wall cutout, gravity fill hose size, and pressure connection style.

  • Security: Lockable hatch includes two keys for controlled access to the water fill point.
  • Fast Fill Venting: Built-in 1/2 inch vent supports faster gravity fill by helping tank air escape.
  • System Match: Confirm your application uses the same gravity fill and city hookup connection sizes before ordering.

R&P Knowledge Hub

Compatibility: Intended for fresh water tank fill applications where the mounting cutout, outside dimensions, and connection sizes match this inlet assembly.

Vehicle / System Fit: Commonly used on RV, camper, and trailer fresh water holding tank systems with gravity fill.

Installation Notes: Verify wall cutout size, overall outside dimensions, gravity fill hose size, vent size, and city hookup thread before installation.

Performance Insight: The integrated vent helps support smoother tank filling, while the built-in check valve serves the pressure-side hookup connection.

Brand & Fitment Note

Selling Brand: Valterra

Application Reference: Any RV or trailer references in this listing describe compatibility, fitment target, or application style only where supported by verified dimensions, mounting points, and connection details.

What This Means: This listing is for a Valterra gravity water inlet hatch, not a guaranteed OEM-branded assembly unless specifically stated and verified.

Before Ordering: Verify cutout opening, outside dimensions, gravity fill spout size, vent size, pressure-side thread style, and included components before installation.

R&P Repair Insight

Fresh water inlet replacements can look similar from the outside while using different backside plumbing. Before purchasing, double-check the cutout size, the gravity fill hose size, the vent hose size, and whether your pressure connection matches the stated 1/2 inch NPT hookup.

  • Cutout Check: Required wall opening is 5-7/8 inch wide x 4-3/4 inch tall.
  • Gravity Fill Check: Gravity fill spout is listed for 1-1/8 inch or 1-1/4 inch hookup applications.
  • Pressure Port Check: Confirm your application uses a 1/2 inch NPT city hookup connection.
