ppr管在电气部分：
卫生间的开关尽量放在室外，若放在室内有淋浴的需加装防溅盒，使用不方便还会增加成本。
卫生间等电位联结线好利用近的柱筋引入（若有均压环更好）。
PPR tube in the electrical part:
The switch of toilet should be put outdoors to the full. If it is put indoors with shower， splash proof box should be added， which will increase the cost if it is inconvenient to use.
The equipotential bonding line in the toilet should be introduced by using the bar near the column (if there is a grading ring， it is better).
·安装完毕后的试压工作，试验压力为工作压力的1.5倍，且压力值不得小于0.6MPa，ppr管材，测试时间约20-30分钟。
·管材安装要遵循“水走天”原则，PPR管材，避免后期维护损害管道。
·安装过程中要及时封住管材开口处，避免杂物进入管道系统
Tips for PPR tube installation
·After installation， the test pressure is 1.5 times of the working pressure，ppr管材规格， and the pressure value shall not be less than 0.6MPa， and the test time is about 20-30 minutes.
·Pipe installation chould follow the principle of "water goes to the sky" to avoid damage to the pipe during later maintenance.
·In the process of installation， the opening of the pipe should be sealed in time to avoid impurities entering the pipe system
