WHAT CAUSES A CLOGGED DRAIN?
When a clump of debris or hair tries to pass through the pipe, It can become stuck and completely block the flow. The result is a clogged bathtub or sink drain.
You may think to yourself, what is causing my sewer to back-up?
A clogged drain is typically caused by the gradual buildup of organic matter like hair and grease on the inside walls of drain pipes.
There are many causes of a main sewer backup. The main three are clogging, tree roots and broken and/or collapsed sewer lines.
Clogging is most caused by root intrusion and grease buildup. Tree roots penetrating sewer lines are a common problem experienced by city residents.
Over the years the sewer lines develop cracks and fractures due to old age. Roots thrive most in warm, moist and nutrient dense environments.
