以下是对卫生间水管安装及漏水问题处理的详细介绍。

一、卫生间水管安装注意事项

进水应设有室内总阀，安装前必须检查水管的连接配件是否有破损、砂眼、裂纹等现象。安装厨、卫管道时，管道在出墙的尺寸应考虑到墙的砖贴好后的最后尺寸，即预先的考虑墙砖的厚度。

墙体内、地面下，尽可能少用或不用连接配件，以减少渗漏隐患点。连接配件的安装要保证牢固，无渗漏。设计时应考虑洗衣机用水龙头位置，下 水布置，以及电源插座位置是否合适。

水路改造完毕要做压力实验，实验压力不小于0.6MPa，时间为20-30分钟。淋浴混流阀左右位置正确，一般装在浴缸中间（先确定浴缸尺寸），高度为浴缸上中150-200mm；连杆式淋浴器根据房高和业主需要来确定出水口位置。

坐便器进 水出口尽量安置在能被坐便器挡住视线的地方。一般要留在马桶下 水口正中左方200 mm处。

First, find the source of the leak. Leaks are usually at a specific point, such as water pipes embedded in walls that become damp but still visible on the wall surface.

Second, mark the leaking water pipe if it is inside the wall or outside with a marker.

Thirdly, apply waterproof tape around the leaking area before repairing it to prevent further damage and ensure safety during repairs.

Finally, after marking and applying waterproof tape, use foam sealant to cover any gaps between fittings and pipes for additional protection against leaks.
