*Water Hammer: Sudden closure of a control valve or stopping of a pump produces excessive pressure surges in a
pipeline. These pressure surges can cause signicant damage to equipment and/or appliances directly attached to
the water line. Water hammer is usually noted due to the characteristic banging sounds when valves on the line are
suddenly closed. Water hammer conditions must be immediately remedied, and damage to systems as a result of this
condition are not covered under warranty.
