`Polybutylene pipe and fitting failures`

Eventually Hoechst Celanese paid a 900 million dollar class action trust fund to help fix these things. And DuPont did something larger but it was confidential. They probably paid a billion or a billion and a half to make it so people could take these things out of their house. A similar type of thing with polybutylene, for plastic fittings and things. So you've got to be careful when you introduce a brand new material into some commodity product to make sure you thought about all the important things.
