RV Gravity Water Filling Port 80mm White for Motorhome Caravan Water Tank Inlet

Keeping your recreational vehicle's fresh water tank topped up is essential for extended trips, but standard pressurised hook-ups are not always available. This gravity water filling port offers a simple, dedicated solution for manual refilling using a hose or a container. Designed to install flush into the side of your motorhome, caravan, campervan, trailer, or boat, it provides a neat and functional water inlet that keeps connections secure and accessible. The white finish helps it integrate smoothly with exterior panels, and the clearly defined 80mm hole size and 38mm inner pipe diameter make installation straightforward for standard RV plumbing.

Design and Construction Details

This filling port is built around a practical, no-fuss design philosophy. All dimensions are clearly specified to support accurate installation and reliable hose connections.

Material and Build

While the exact materials are not detailed in the source text, the unit is constructed as a functional gravity water inlet intended for external use on recreational vehicles. The white colour is a standard choice for RV accessories, helping the port blend with typical body panels.

Size and Installation Fit

The port requires an 80mm diameter hole for flush mounting. This precise specification ensures a neat, secure fit into the sidewall of your motorhome, caravan, or trailer. The external water pipe inner diameter is 38mm, which is a common size for standard RV water hoses and fittings.

Installation and Compatibility

This accessory is designed for easy integration into existing RV plumbing systems. Its specifications match commonly available components, so retrofitting or new builds are straightforward.

Mounting Process

Mount the port using an 80mm hole saw in a suitable location on the vehicle exterior. Secure the unit flush against the panel, ensuring a clean, water-resistant seal.

Hose Connection

The 38mm inner diameter of the external water pipe accommodates standard gravity-feed hoses or container spouts. Simply insert the hose and pour water into your tank. No pressurised system is required.

Practical Benefits for RV Owners

This gravity fill port solves the common problem of awkward tank refilling, especially in remote or unpowered campsites where a mains water connection is not available.

Convenient Gravity Refills

With this port, you can easily fill your fresh water tank using a collapsible water container or a standard garden hose. The gravity-feed design is simple and reliable, with no complicated valves or electronics.

Dedicated Water Inlet

Having a dedicated filling port keeps your main door or access hatch free for other uses. It provides a clean, organised look and reduces the risk of dirt or debris entering the water system.
