一般在给排水设计阶段会考虑到户内给水设施检修情况，因此会在卫生间及厨房

Generally, in the water supply and drainage design stage, the maintenance of indoor water supply facilities will be considered. Therefore, control valves will be installed on the upper part of the water supply pipes in the bathroom and kitchen. Once water leakage occurs during use, the valves can be closed in time to avoid serious consequences. Since the materials, corrosion resistance and pressure resistance of various valves used in the water supply piping system are not the same, the valve selection should be selected to meet the design specifications, and combined with the size of the pipe diameter, the pressure level and the temperature of the medium in the pipe, etc. Circumstances, choose all copper valves, all stainless steel valves, plastic valves or cast iron copper core valves, etc.

Generally in the water supply and drainage design stage will take into account the in-house water supply facilities maintenance situation, so in the bathroom and kitchen to add to the upper pipe control valve, in use once the water leakage situation can be closed valve in time to avoid serious consequences. Due to the various types of valves used in the water supply pipeline system material, corrosion resistance and pressure resistance are not the same, in the choice of valves should choose in line with the design specifications, and combined with the size of the tube diameter, the pressure level and the temperature of the media in the tube, choose the all-copper valve, all-stainless steel valve, plastic valve or cast iron copper core valve.

Generally, in the water supply and drainage design stage, the maintenance of indoor water supply facilities will be considered. Therefore, the control valve will be installed on the upper part of the water supply pipe in the toilet and kitchen. In case of water leakage, the valve can be closed in time to avoid serious consequences. Due to the different materials, corrosion resistance and pressure resistance of various valves used in the water supply pipeline system, the valve that meets the design specification should be selected when selecting the valve, and all copper valve, stainless steel valve, plastic valve or cast iron copper core valve should be selected according to the pipe diameter, pressure level and medium temperature in the pipe<br>
