Duplex plumbing issue not covered

[Daniel Ziner]

Good morning everyone.  Wanted to see what your thoughts are on this.  I closed on a duplex a few month ago and now there is a plumbing issue where the plumber says that they'll need to change both main lines to the house and reroute the piping since it's all leaking.  He said it will cost $12,335.  I got the house inspected and in the inspection report it never mentioned the standing water so it was for sure leaking prior to closing.  I am going through the warranty company that the inspector has, but they said they will only cover a small amount of the repair.  Any advice moving forward would be appreciated.  Thanks!

Well it took you several months for you to uncover the issue....how was it then supposed to be discovered in a couple hour time frame from the inspector? Youve got an hour or two with an inspector who is a generalist, not a specialist, to identify problems they can visually see at that moment in time. If they cant see it, they dont know. If there isnt evidence of a leak during that 2 hour period of time, they dont know.
