Can I get restitution on a plunmbing issue on new construction?

I just recently moved into new construction that is only 8 mths old and is under warranty. I recently had a water leak on a main pipe in a wall due to a broken seal. this water damage ruined a hardwood floor. the bulider said they will repair the wall the cut into but not replace the floor since i had the floors installed afetr i moved in. but my floor did not cause the problem thier plumbing did. what should i do. i am not going to run and clain it on my hoemowners right away when this was not my fault it was the builders. oh and by the way there are others in my bulding that have had plumbing issues.
