Cut sheet rock in the ceiling and did not see any moister. The leak in in the corner wall where sewer stack drops. Can not cut wall from garage due to sheer wall. will need to access from the interior living room area but there are 4’ wood paneling on the wall that needs to get removed. 请问 1. 有没有什麽修理方法不用在房间里打洞？2. 一般情况下，修理费用大概范围？3. 要不要报保险公司？先谢谢了！
I can tell you exactly where the leak came from...
1. this is sewage leak, don't bother looking for other sources.
2. the leak is at the junction between horizontal 4 inch black pipe (shown in the top part of the last picture) and the vertical pipe , hidden behind the drywall underneath the cut ceiling. If I guess correctly this vertical pipe is
an older cast iron pipe. The horizontal section of the black pipe is the source of problem because it trapped a small amount of water to keep the top of the cast iron pipe wet and leads to rust in the long run.
房客发现出租房车库地面有漏水。我们同意 plumber在车库房顶开了洞。结果他说还需要再在房间里再开洞。这比较麻烦。房间墙上有wood panel. 下面是他写的：

我前不久有个很类似的情况
房子主排管位于房子中间贯穿上下。三楼有一个洗手间管子从二楼天花板上面横穿了很长距离然后T字与垂直的主管相交。
你读到这里应该看出问题。。长距离横的管子意味着不可能有足够的坡度，水流慢，容易积累东西，而腐烂的东西产生的化学成分加速金属的腐蚀。
同样的把二楼的天花板凿了一块可以够到这个接口。
这个令我很头痛，因为这个T形接口可没法换（不是不可以，是大麻烦因为得把主管子截断，那个铸铁的上半部有上百斤一直通到楼顶在墙里谁能举着）。我现在是用胶在整个外面抹一层，能管几年管几年。不过，这是流水，没有压力，问题不大。
你要知道那个黑管子向右方向通到哪里去。漏的地点离现在打开的地方不远。
其实车库这面垂直的墙可以敲个洞看看，是不是垂直的管子在后面。
或许你有这个房子管道走向的图。
你要是能告诉我这个房子二楼用水的地方都是怎么分布的画个图给我，和相对于照片里显示的位置，我大概可以说得更靠谱一些。
凿那个木板墙实在太不合适了，尽量避免。如果从现在的洞里手伸进去能摸到漏的地方你就安生了，抹把胶就可以了。
不知在哪里可以拿到房子管道走向的图？
要是漏点在WOOD PANEL 后，你连DRYWALL都不用修了，掀一片WOOD PANEL在放回去就好了。
