How to check the quality of modern toilets
Hello guys！Now I'll show you how to check the quality of toilets in factory.
First, the toilets should be filled with water and stay for 24 hours. We need to check if any leakage.
Second, we need to use more than 100 balls to check the flush power of toilet.
Then, we'll flush the red ink to check if the flushing hole is blocked.
If the toilet pass all the steps, it's good quality.
