Concealed shower and bathtub faucet After purchasing a concealed basin faucet, the valve core of the faucet should generally be pre-buried in the wall. Before pre-embedding, consider the thickness of the bathroom wall. If the wall is too thin, the valve core will not be able to be embedded. Do not remove the plastic protective cover of the valve core during pre-embedding, so as not to damage the valve core by cement and other chores during pre-embedding. In addition, when pre-embedding the valve core, you should also pay attention to the up and down, left and right directions of the valve core, so as to avoid the wrong valve core. The installation of the concealed basin faucet is due to the high frequency of use of the kitchen faucet, and it is easy to loosen when it is moved around. All requirements for stability are taken for granted, so the lock nut must be tightened. At present, there are a number of faucets in the building materials market which are screw pipes fixed by enlarged nuts, which have excellent stabilization effect. The obvious effect will become the trend of the generation trend.
