What causes slow draining sinks?

What Causes Slow Draining Sinks?

Slow draining sinks are typically caused by:

• ✔ Hair buildup: In bathroom sinks and showers, hair is the most common cause of blockages, combining with soap scum to form stubborn clogs.
• ✔ Soap scum accumulation: Soap combines with minerals in water to create a sticky residue that gradually narrows drain pipes.
• ✔ Grease and food particles: In kitchen sinks, cooking oils, fats, and food waste can solidify and stick to pipe walls, restricting water flow.
• ✔ Foreign objects: Items accidentally washed down drains (jewelry, small toys, excessive toilet paper) can cause partial blockages.
• ✔ Mineral buildup: In areas with hard water, mineral deposits can accumulate inside pipes, gradually reducing their internal diameter.
• ✔ Tree root intrusion: For slow drainage affecting multiple fixtures, tree roots may have infiltrated your sewer line.
• ✔ Improper drain slope: Plumbing drains require proper downward slope; if incorrectly installed, gravity won't effectively move water.

Regular maintenance can prevent most clogs, but for persistent slow drains, our professional drain cleaning services can restore proper flow. We use methods ranging from cable machines (snakes) to high-pressure hydro-jetting depending on the severity and cause of the clog.
