Pouring hot water down the sink might seem like a harmless act, but it can actually cause significant damage to pipes and drainage systems. This impact is not only economically detrimental but also harmful to the environment.

Understanding the Risks of Hot Water in Your Sink
Premature Aging of Drainage Pipes
In the past, sink drain pipes were commonly made of metal. Nowadays, plastic pipes that are more heat tolerant are often used. However, repeatedly pouring hot water can still accelerate the aging of these pipes, which eventually shortens their lifespan. Consequently, you might find yourself spending more on pipe repairs and replacements.

Deformation and Cracking of Drain Pipes
The heat resistance of drain pipes varies by the materials they are made from. For example, PVC drainage pipes are widely used, but they may be unable to withstand temperatures above 60 degrees. If hot liquids like soup or blanching water around 90 degrees are poured into them, it can cause the pipes to deform, crack, or even burst due to the heat.

Simple Strategies to Protect Your Kitchen Sink Drainage
Here are some straightforward tips provided by experts to help maintain your sink’s drainage system:
Invest in More Effective Trash Filters
While most kitchen sinks already have filters to stop large food particles or grease from entering the pipes, upgrading to a larger filter can significantly reduce the likelihood of blockages.

Dispose of Leftover Food Properly
Rinsing small amounts of food residue left on plates directly down the sink may seem convenient, but even small particles can accumulate over time, leading to serious blockages. Always scrape leftover food from plates into the trash before washing.

Regularly Clean Your Sink and Drains
If you notice any changes in your drainage system, it might be time to give your sink and drains a thorough cleaning using a safe cleaner. Regular maintenance can prevent blockages and keep everything flowing smoothly.
