Preloc is a flexible and easy-to-install water trap for bathrooms. These water traps, equipped with both horizontal and vertical telescopic features, are extremely space saving as they can be mounted onto the back wall. That means more space for your drawers! Another great thing is, that two washbasins can be combined using only one outlet pipe. For bowl type wash basins, we recommend Preloc Top Mounted water traps. As with all Prevex products, Preloc water traps comply with the European standard EN-274.
