Another man died at a health-care facility after a lack of water pressure made medical treatment impossible. ___OKLAHOMA CITY -- Oklahoma City Mayor David Holt pleaded with residents Thursday to limit water usage after city officials said some hospitals faced what Holt called a crisis because of a sharp drop in water pressure. Integris Baptist lost water pressure at two of its hospitals, according to city utilities director Chris Browning. The drop in water pressure was due largely to customers running faucets to prevent frozen and burst water lines, and nearly tripling the amount of water used, according to city utilities director Chris Browning. She says “‘Frozen’ is always a good choice.”Ad___AUSTIN, Texas -- Texas Gov.
