Builder caused a water leak

[Konstantin Za]

Hello, I have a water leak at my property. Water damage is quite big. The root cause is a nail in the pipe. Nail get rusted after 3.5 years of house build and water started going outside the pipe, flooded floor, ceiling and walls. It there any way to get reimbursed by home builder (richmond american homes)? Any recommendations? I also have property on the market for sale now and missed a great offer die to property damage. I have all pictures and a piece of pipe with rusted nail in it.

thanks
