What Causes Blocked Drains — And How to Prevent Them

Blocked drains are one of the most common plumbing issues homeowners face.

Understanding the causes can help prevent unexpected plumbing emergencies.

Common Causes of Blocked Drains

Tree Roots
Roots naturally seek moisture and can enter pipes through small cracks.

Fat, Oil and Grease
When washed down sinks, these substances solidify inside pipes.

Wet Wipes and Hygiene Products
Even “flushable” wipes often cause blockages.

Old or Damaged Pipes
Older pipe materials are more prone to collapse or restriction.

How to Reduce Your Risk

• Avoid pouring grease down the sink

• Use drain strainers

• Schedule periodic inspections

• Address slow drains early

Regular maintenance can prevent costly emergency callouts.
