Blocked drains can be caused by many reasons and, if left untreated, can cause costly damage to your home or business. These are the most common reasons for blocked drains, and how you can prevent them.

Foreign objects such as food particles, hair, soap residue, and paper products can cause blocked drains. These substances stick to pipes and block water flow.

To prevent these blockages from occurring:

Cooking oil should be disposed of in the trash, not the sink
Avoid pouring leftover food debris or coffee grounds into the sink
To prevent hair accumulation, install drain covers in bathtubs, sinks, and shower stalls
Use minimal toilet paper when flushing

Tree roots often grow toward water sources such as cracked pipes or pipe joints where they can infiltrate and eventually cause a complete blockage within the pipe.

Blockages can be caused by grease buildup. Many people pour hot grease down their kitchen sink since it’s liquid form making it easily escapes from dishes but congeals quickly once it cools off deep inside your pipes causing stubborn clogs.

Slowly draining water
Multiple blocked fixtures
Mold growth
Foundation cracks

Regular inspections of your sewer lines with CCTV inspections are recommended so that professional repair companies can detect and correct any problems.

Bad pipe design or incorrect installation can cause blocked drains. It is possible for large debris to build up in unreliable areas, causing blockages.

Hire professionals to install pipes correctly and make sure they meet all standards.
