The domestic water system is chlorinated by the local utility and contains some microbiological matter that is known to attack metallic piping components. Both the brass fittings and the stainless steel clamp bands failed. The failure mechanisms were determined to include problems with the design and metallurgy of the components, installation deficiencies and the corrosive nature of the water supply.
