Nowadays, in home decoration, tiles are used to cover the floors and walls of kitchens and bathrooms. Although leak-proofing is done before laying tiles, it cannot be guaranteed that the leak-proofing will be foolproof. Moreover, you cannot guarantee that there will be no leakage at the interface between the faucet and the cold and hot water pipes when installing the faucet.

　　No matter which way is used to lay wall tiles, there must be a certain distance from the wall. The reserved lengths for the water outlet pipes under the washbasin and the shower room in home decoration are different. Generally, the Angle valve under the washbasin does not need a decorative cover. The cold and hot water pipe joints here can be left longer. Later, it can be observed more intuitively whether there is any leakage at the joints. Even if there is leakage, it is unlikely to seep between the tiles and the wall. However, the interfaces of shower enclosures are usually left relatively short, and when combined with decorative covers, they can serve an aesthetic purpose. In this way, it becomes very difficult to check whether there is any leakage, and this leakage must be going into the tiles.

　　Over time, water may drip from downstairs.

　　If the decorative cover can be disassembled without the need to remove the faucet as a whole, then it is possible to check whether there is any leakage at the interface. It has greatly increased the convenience for the inspection of water leakage.
