The Whale Watermaster White Inlet Socket with Integrated Pressure Switch provides a convenient external water connection for compatible caravan and motorhome water systems, featuring built-in pressure control, a protective socket cover and a choice of white or ivory finishes.
Designed for caravans and motorhomes using a pressure-switched water supply, this genuine Whale Watermaster socket combines an external water inlet connection with an integrated pressure switch, helping control the operation of a compatible 12V water pump.
The built-in pressure switch responds to changes in water system pressure. When a tap is opened and the pressure drops, the switch activates the connected pump to deliver water. Once the tap is closed and pressure is restored, the switch stops the pump. This provides convenient automatic water delivery without requiring individual microswitches in every tap.
The external Watermaster inlet connection allows a compatible Whale Watermaster pump assembly to connect to the vehicle’s onboard water system. This makes the socket suitable for replacing a damaged or worn existing inlet or for installation in an appropriate caravan water system.
A key advantage of the integrated design is that the pressure switch is incorporated into the inlet socket assembly. This provides a practical solution for compatible pressure-controlled systems, helping keep the water inlet and pump control components together.
The socket features a protective hinged cover, designed to help shield the external connection from rain, dust, dirt and other contaminants when not in use. This is particularly useful for touring caravans and motorhomes that spend extended periods outdoors.
Available in white and ivory colourways, the Whale Watermaster inlet socket can be selected to complement existing exterior fittings. The white version provides a clean, bright finish, while the ivory alternative is particularly useful when matching older caravan installations or cream-coloured external accessories.
The socket is designed for use with compatible Whale Watermaster water connections and suitable pressure-controlled 12V water systems. Its practical design makes it a useful replacement component when refurbishing a caravan, repairing an external water inlet or maintaining an existing water supply installation.
Before ordering, it is important to identify whether your vehicle uses a pressure-switched or microswitched water system, as these socket configurations are different.
