In the bathroom glass vessel sinks, a gap of 2.5 cm is reserved between the side plate glass and the bottom plate glass. The side plate glass and the bottom plate glass are directly connected by glass glue. There is no other connection method between the side plate glass and the bottom plate glass. In the process of gluing, the glass glue is not uniform, and there will be air bubbles, glue shortage, interface and other easy to leak.
When the tank is filled with water, there will be a tension to the outside. When the water is empty, the glass will return to its original state. In this way, the glass glue needs to be stretched and contracted together with the glass, and the air bubbles, joints and glue-deficient places in the glass glue will appear leakage and water seepage after repeated several times.
