This gate valve or ball valve might be installed above ground, often next to the shut-off for the house water, or it might be installed below ground, typically in a green plastic valve box. Emergency service is charged at a premium rate, usually 1-1/2 times the normal rate, so it is helpful to decide what is an emergency and what can be handled in the normal service mode. Any after-hours work or week-end work for the convenience of the customer is at emergency rates. When there is water running continuously at a high rate ? such as a section of sprinklers stuck on or a broken pipe running continuously ? this is a true emergency. Water oozing around one or two heads is not an emergency, and usually is not even urgent. This is a common malfunction that can usually be handled in normal service scheduling..
