Let me start with the conclusion: I used it right, of course it worked.
1. What is an in-wall faucet?
The in-wall faucet is to bury the water supply pipe in the wall. The in-wall faucet directly guides the water to the wash basin/sink located below on the wall. The faucet is independent, and the wash basin/sink is also independent. The washbasin/sink does not need to consider the internal integration of the faucet, so there are more free choices in the shape, so that different spaces and environments have more diversified choices.
The location where the washbasin/sink and the faucet meet is usually the place where rust and bacteria breed the most. With separate faucets and washbasins/sinks, you don’t have to worry about cleaning these locations.
Two forms of wall-mounted faucets.
1. Single control form.
(Single switch rotates left and right to control hot and cold water, and flips up and down to control water output, water will be relatively saved)
(1) One-piece concealed faucet with single control mixing valve.
(2) Separate hidden faucet with single control mixing valve.
(3) Hidden faucet with embedded box for single control mixing valve.
This kind of built-in box not only has an extra cover on the appearance, but also has a different internal structure. The built-in box will come with a level, and the yellow box must be embedded in the wall when it is embedded.
2. Sub-control form.
The sub-control water valve hides the faucet, which means that the hot and cold water are controlled separately, the left is hot and the right is cold, and the middle is the water outlet.
(Double switch, the hot and cold water should be adjusted separately. The water flow is large when the water temperature is adjusted to the appropriate temperature, which is not very water-saving. If only hot water is used, it is easy to burn. It is not suitable for the elderly and children. More decorative)
