A blocked drain refers to a situation where water fails to drain away from your sink, toilet, shower, or any other water system. The blockage can occur due to various reasons such as:

• Accumulation of fats, oils, and grease that solidify in the pipes.
• Build-up of hair, soap, and other debris in the pipes.
• Intrusion of tree roots into underground pipes.
• Misuse of toilets, where non-degradable materials like wipes are disposed of through the sewer system.

A blocked drain can cause several issues like unpleasant odours, slow draining, and overflowing water. If not handled promptly, it can also cause damage to your property and pose health hazards.
