B&B 94249/94250 Compact RV Gravity-Fill Hatches & Caps

When an RV's gravity-fill water hatch breaks, the replacement must fit the wall opening and allow the correct tank-fill and vent hoses to connect behind it. B&B Molders 94249 and 94250 are compact keyed gravity-fill hatches. They connect to the onboard fresh-water tank; they are not pressurized city-water connections.

Choose the compact gravity-fill hatch

For this compact hatch the maker specifies 1-inch collar depth and 2¾-inch total depth. The fill spout accepts 1¼-inch or 1⅜-inch water-fill hose, and the tank-vent connection is ⅜ inch. Measure the original opening as well as the hoses.

Identify the gravity-fill components

Cap only or cap-and-spout assembly?

If the hose connection and spout are sound, a cap-only replacement may be all that is required. If the spout is cracked, identify the correct cap-and-spout version. A replacement door is a separate component and does not include the hatch housing.

Before replacing a gravity-fill hatch

1. Check the outside trim size and measure the actual cutout behind the original hatch.
2. Confirm the fill hose and vent hose sizes at the rear of the original assembly.
3. Match the door colour, hinge arrangement and 391/751 key configuration where relevant.
4. Ensure the filler and tank vent are connected properly and follow the RV manufacturer's weather-sealing and tank-filling instructions.
