Many owners who have been renovating for many years have an experience that after long-term use of the wash basin, dirt is likely to adhere to the basin sink, and the water does not go down in the sink. In fact, this is because the sink is not cleaned. This highlights a problem. When buying a basin drain, you must buy an easy-to-clean one, and install it in strict accordance with the installation steps and methods of the basin drain, otherwise it is easy to cause water in the basin. So how do you install the basin drain? The following example illustrates that the drain installed in the example is a bounce drain with overflow holes. The installation steps of other drains are similar to this.
The bouncing core of the drainer is the only way to enter the basin, so it is easy to hide dirt and dirt. The result is that the bouncing core can not bounce, or can not bounce. In fact, bounce cores are generally made of metal (usually made of copper), unlike some zinc alloys (such as some low-quality faucets), so they are generally not broken. They can’t bounce because they are dirty. Just clean them.
