MaJoCompTec Watertwin - compact and durable water tank adapter with a connection that is compatible with the Gardena system. The connection features an integrated double coupling for convenient and hygienic filling of your fresh water tank. With this water filling aid, you can be sure that the filling hose stays where it should - on the tank connection! Easy to attach to the filling neck - no nasty surprises when the hose detaches itself from the cap and falls on the ground, taking on a life of its own. When the tank is full, the excess water will escape through the overflow on the refill adapter. There’s no need to worry about excess pressure being put on your water system. After filling the tank, the two water hose connections are attached to the integrated double coupling. This seals the hose - water won’t leak out and pests won’t get inside the vehicle. Suitable for many motor home and caravan models. Please check the pictures before ordering and select the Watertwin water tank adapter that matches your tank cap. Contains: 1 x MaJoCompTec Watertwin water tank adapter with a connection that is compatible with the Gardena system. The connection features an integrated double coupling and overflow function, 1 x short hose extension 16 x 20 (type and colour of your choice). The filling nozzles, tank caps, Gardena plugs and hoses shown in the pictures are not included in the delivery. Their only purpose is to show how the cap works and so you can compare it to the original sealing cap.
