 A plumbing emergency at the state legislature. And no, the building's not flooding. Lawmakers are the ones who caused this emergency in the plumbing industry.

People in the business say the results could cause job loss and the costs could explode. Water shutoffs are even possible and potentially dangerous stuff getting into your drinking water.
