Blocked Drains New Zealand: Causes, Solutions & Costs
Blocked drains are one of the most common plumbing issues in New Zealand homes and businesses. Learn about causes, professional solutions, and how to prevent future blockages.
Common Causes of Blocked Drains in NZ
Tree Root Intrusion
New Zealand's mature trees often have roots that infiltrate drain pipes, especially in older properties with clay or concrete pipes.
Grease & Fat Buildup
Kitchen waste, cooking oils, and fats solidify in pipes, creating stubborn blockages that worsen over time.
Hair & Soap Scum
Bathroom drains commonly block due to hair, soap residue, and personal care products accumulating over time.
Foreign Objects
Items flushed down toilets or washed down sinks that shouldn't be there, including wet wipes, sanitary products, and toys.
Pipe Damage
Cracked, collapsed, or misaligned pipes due to ground movement, age, or poor installation can cause recurring blockages.
Storm Debris
Leaves, dirt, and debris from New Zealand's frequent storms can overwhelm drainage systems, especially in autumn.
