What Causes Blocked Drains?
Blocked drains can occur for a variety of reasons, including:
Fat, Oil & Grease Buildup
These substances solidify in pipes, leading to severe restrictions in water flow.
Hair & Soap Residue
Accumulated hair and soap scum can create blockages in bathroom sinks, showers and bathtubs.
Tree Root Intrusion
Roots can enter underground pipes, causing cracks and obstructions that require professional removal.
Foreign Objects & Wet Wipes
Items such as sanitary products, wet wipes and excessive toilet paper can quickly block waste pipes.
Collapsed or Misaligned Pipes
Structural issues in drainage systems can lead to persistent blockages that require repairs or pipe replacements.
Food Waste
Disposing of food scraps down the kitchen sink, even with a garbage disposal, can lead to blockages over time.
