Whale Watermaster caravan water inlet (Whale Watermaster socket)
Where Whale Watermaster socket is used, its real dimensions, and how to connect it.
Used on: UK and European touring caravans and motorhomes with a Whale Watermaster external inlet socket.
The Whale Watermaster connector clips into both Whale Watermaster and Truma Ultraflow inlet sockets, so the two brands are cross-compatible at the socket. Older Truma Crystal II sockets need a separate adapter. Onboard, caravan plumbing is 3/4 inch BSP for the mains inlet.
Quick-connect click fittings from Hozelock, Gardena and Karcher are proprietary and do not interchange. They all sit on top of a standard thread underneath, so the reliable way to move between brands is to adapt at the threaded tap or hose-end fitting, then use each brand's own connector above it.
