Why should not you pour hot water into the sink?

Why You Should Never Pour Hot Water Down the Kitchen Sink?

Pouring hot water down the kitchen sink is a common habit in many households, especially when disposing of leftover boiling water from cooking. While this may seem convenient, it can actually cause serious damage over time. It is recommended that you reconsider this habit to maintain a clean and safe kitchen environment.

The Dangers of Pouring Hot Water Down the Sink

Most kitchen sinks are equipped with drainage pipes that filter wastewater. When hot water is poured directly into the sink, it flows into these pipes, which can lead to several long-term issues.

1. Reduces the Lifespan of Drain Pipes

Most kitchen drain pipes are made of plastic. Although some types can withstand moderate heat, continuous exposure to hot water will gradually weaken them and shorten their lifespan.

Generally, drain pipes can last between 30 to 50 years, but if exposed to hot water frequently, their durability will be compromised, leading to premature replacements.

2. Causes Pipe Deformation and Cracking

Some pipes, especially those made of PVC, cannot withstand temperatures above 60°C. Since boiling water from cooking can reach up to 90°C, pouring it directly into the drain can cause pipes to warp, soften, or even crack. This may lead to leaks, costly repairs, and potential damage to kitchen furniture and cabinetry.

How to Prevent Grease Buildup in Drain Pipes

During cooking, grease, food scraps, and leftover liquids can easily flow into the drain, causing blockages over time. Some people believe that pouring hot water down the drain can help clear grease buildup, but in reality, hot water does not effectively dissolve grease, making it an ineffective solution.

To prevent drain clogs caused by grease accumulation, consider the following two approaches:

1. Pre-Clean Grease from Dishes

To make dishwashing easier and prevent grease from accumulating in the pipes, wipe excess oil off dishes, pans, and utensils using a paper towel or kitchen cloth before washing them. This simple step helps remove most of the grease before it reaches the sink.

2. Use a Drain Cleaner Regularly

If you notice slow drainage or unpleasant odors coming from your sink, it may be a sign of grease and residue buildup inside the pipes. To keep the drainage system clear, use a drain cleaner periodically to dissolve accumulated grease and debris.

Using a drain cleaner is straightforward—simply pour it down the sink, and it will penetrate deep into the pipes, breaking down clogs without damaging the pipe material. In addition to clearing blockages, most drain cleaners contain antibacterial agents that eliminate bacteria and prevent foul odors, ensuring a clean and hygienic drainage system.
