A combination city/gravity water-fill panel provides two separate connections: the pressurized city-water inlet and the gravity-fill spout for the RV's onboard fresh-water tank. B&B Molders makes several look-alike assemblies that differ by check-valve material and wall opening. Identifying the complete panel and its service pieces helps avoid replacing the whole hatch for a missing cap.
Which B&B water-fill panel fits your opening?
| Panel | City-water valve | Wall opening | Outside trim |
|---|---|---|---|
| 94253 | Brass | 4¾ × 5⅞ in | 6⅞ × 7⅝ in |
| 94254 | Plastic | 4¾ × 5⅞ in | 6⅞ × 7⅝ in |
| 94224 | Brass | 3¾ × 6 in | 5⁵⁄₁₆ × 7⁹⁄₁₆ in |
The larger lockable 94253/94254 centers have a 1½-inch collar and approximately 3¼-inch total depth. The smaller 94224 is a different recessed design; its listed total depth is 2½ inches. The wall openings are not interchangeable.
Identify the separate water connections
Connection identification — simplified, not to scale
City-water side
Hose inlet → check valve → ½-inch male pipe-thread plumbing connection
Gravity-fill side
Fill cap → water-fill spout → 1¼- or 1⅜-inch tank fill hose
Vent line
Separate ⅜-inch tank vent connection on the specified water center
Find the correct service piece
| Original component | Replacement number | Use |
|---|---|---|
| White hatch door | 94182 | Outer keyed-hatch door for the specified lockable centers |
| City-water inlet plug | 94206 | White rubber cap for a compatible pressurized inlet |
| Gravity fill cap | 94243 | White plastic bayonet cap and retaining lanyard |
| Gravity spout, strap and cap | 94245 | Replacement white fill-spout component set |
| White plastic check valve | 94210 | Matching plastic city-water valve used in 94254 |
For 94253 and 94224, the manufacturer specifies a brass city-water check valve. Do not substitute the white plastic check-valve component solely because the exterior panel is white. Match the original fitting type and connections.

View 94210 productBefore replacing or repairing a water-fill center
- Measure the exterior opening through the wall and the overall trim size.
- Identify whether the city-water side uses brass or plastic check-valve construction.
- Match the city-water thread, tank fill hose diameter and vent connection to the existing plumbing.
- If only a cap is damaged, confirm its type before ordering a complete assembly.
- Follow the RV manufacturer's water-system service and sealing instructions, then inspect the connections for leaks.
Manufacturer component reference
The B&B Molders official parts catalog (PDF) shows the matching hatch or water-inlet assemblies and factory replacement part numbers on printed pages 4–5. The PDF may open in a separate viewer on mobile.
For other freshwater connection shapes, compare the Valterra fill-hatch reference. These are different manufacturer part families, not interchangeability claims.
