Why does my sink separate?
For example, a new disposer could have been installed and the angles of the pipes are such that the weight of the disposer and the angles of the pipes stress the sink/counter joint. When installing disposer, especially when changing from a 1/3 hp to a full hp, the weight is quite a bit more and usually larger. Because it is larger, the pipes will likely not fit without changing the angles. If installed by stressing the pipes, it will in turn, stress the sink which might be why it continues to separate. Glued pipe fixtures require replacement to get the right angles. Hope this helps.
