There are a number of factors that can lead to a blocked sink. The most common causes include oil and fat solidified on the walls of your pipe, an accumulation of hair or food waste, a buildup of soap scum (typically caused by soap combining with the excess minerals in hard water), and small items such as toys trapped in the drain.
Understanding how your sink can get clogged should enable you to take preventative action before a blockage occurs, such as installing drain stoppers to catch hair and not pouring oil or fat down the sink.
