Wall-mounted faucet installation – Mounting a wall-mounted tap requires the exact spacing of the connection stubs mounted on a concealed installation. For this purpose, special eccentric connectors are used. Their use does not require a very precise arrangement of hot and cold water pipes. Rotating both fasteners around their axis will decrease or increase the spacing, and thus the exact matching to a specific type of battery, even from different manufacturers. The connectors must be selected with the dimensions of the threads for the tap and nozzles.
