If we had the opportunity to buy another Pulte home, we would pass. Our house is only 12 years old and we saw that some ceilings had been redone obviously to fix water leaks. We made the mistaken assumption that the leaks were all fixed by the previous owner. After living here only three years, we've had open three walls and ceilings to fix leaking plumbing. That does not count the leaky house-bibs we had to replace outside.
The worst part is the noise the water makes. The study on the main floor is located directly below the master bath. When anyone runs water or flushes the toilet upstairs, we can't hold a normal conversation on the phone because the water noise in the pipses is so loud.
