Why You Should Never Pour Cooking Fat Down the Drain

As convenient as it may seem to pour leftover cooking fat down the drain, this common habit can cause serious plumbing issues over time. At Response Plumbing, we've seen firsthand how seemingly harmless actions can lead to a major blocked drain problem.

How Cooking Fat Clogs Your Drains

Cooking fats, oils, and grease (FOG) are notorious for causing severe blockages. When you pour hot fat down the sink, it may flow away easily. But as it cools in your pipes, it solidifies, sticking to the walls of your drain. Over time, this builds up into thick, stubborn clogs that can completely block your pipes. Once congealed, regular supermarket drain cleaners are often not enough.

The Impact of Fatbergs

Fat and grease don't just block your home's plumbing — they can create fatbergs in the public sewer system. These large masses of congealed fat, oil, and other non-biodegradable materials cause significant damage to Auckland's sewage networks.

Proper Disposal Methods

Cool and dispose in the bin: Allow the fat to cool and solidify, then scrape it into a container and bin it. Use absorbent materials: Pour liquid fat onto paper towel and bin it. Recycle where possible: Some Auckland facilities accept used cooking oil for recycling.

Signs You May Have a Blocked Drain

Slow-draining water, foul odours, and gurgling sounds are all early warning signs. When these issues arise, call a professional drain unblocker before it escalates.

If you're experiencing a blocked drain in Auckland, Response Plumbing provides fast, efficient drain unblocking services for residential and commercial properties.
