Main Reasons for Blocked Drains

Residue Buildup
Over time, grease, bits of food, hair, soap, and other debris can accumulate in your pipes. This buildup narrows the passage, slowing drainage and eventually causing a clog.

Lime and Mineral Buildup
In areas with hard water, minerals like calcium and magnesium can deposit inside pipes. These deposits gradually reduce water flow and contribute to stubborn blockages.

Foreign Objects
Sometimes small objects accidentally fall into drains—like jewelry, toys, or sanitary products—which can get stuck and block water flow.

Tree Roots
Roots can penetrate older pipes, causing partial or complete blockages in underground plumbing.

Pipe Damage or Misalignment
Broken, cracked, or misaligned pipes can trap debris and prevent proper drainage.
