My house is fairly new just built I close in two days nand now mmy toilet has a hairline crack on the tank that's leaking,what do I do?

I think you should take that problem up with the builder before for you close. The toilet needs to be replaced, but not at your expense after you move in.

I agree with Tickle, builders problem. As far as I know there is no acceptable method of repairing a cracked toilet. Even if the leak is stopped, there is both a sanitation and appearance problem.

Bofore you close have the seller replace the tank. Good luvk in your new home. Tom
