3 may need trench digging machine

excavator. 个体户( or dad son team) may be cheaper. Does it include landscape work after trench work?

所有跟帖： 

• 3需要凿开两处院子里的水泥地，把新水管放到旧水管里面去，连接到City line。是，寻找有执照的个体户水管工再估价看。 -Erin123- ♀ (0 bytes) () 08/22/2024 postreply 22:10:59

• Can people insert new pipe into old pipe from the end? -RomaVacation- ♂ (0 bytes) () 08/22/2024 postreply 23:14:38

• Maybe CIPP (Cure-in-place Pipe) lining? -yuanshangdu- ♂ (374 bytes) () 08/23/2024 postreply 00:10:12

• 读了你的pipe bursting，很有用的信息，感谢分享，pipe bursting是水管工建议的其中一个方案。 -Erin123- ♀ (0 bytes) () 08/23/2024 postreply 09:18:12
