There are several reasons why a drain can become blocked.
Here are some of the most common ​causes of blocked drains:

• 
  Foreign objects: Items such as hair, soap residue, food particles, and small objects like toys or jewelry can become lodged in the drain and cause blockages.
• 
  Grease and Fat: Grease and fat can solidify in pipes and accumulate over time, narrowing the pipe diameter and resulting in blockages.
• 
  Root Intrusions: Tree roots can infiltrate pipes through cracks or joints in the pipes, causing blockages and damage to the plumbing system.
• 
  Buildup of Organic Material: Leaves, twigs, and other organic material can build up in exterior drains and gutters, eventually causing blockages.
• 
  Misaligned Pipes: Displaced or misaligned pipes can cause blockages, preventing water from flowing smoothly through the drainage system.
• 
  Broken Pipes: Damaged or broken pipes can cause blockages by impeding the flow of water or by allowing soil and debris to enter the system.
• 
  Sediment buildup: A buildup of sediment and minerals from hard water can accumulate in pipes over time, causing blockages and reducing the efficiency of the plumbing system.

These are just some of the common reasons why a drain can be blocked. It is important to take steps to prevent blockages, such as by carefully disposing of waste, avoiding flushing non-degradable items down the toilet, and ensuring that your pipes are well-maintained.
