ABSTRACT:
An improved water hammer suppressor which is generally in the form of a first vertical tube closed at its upper end connected into a water distribution piping system at its reduced lower end portion and which in normal operation eventually becomes water logged and must be drained. To facilitate efficient draining of the device when the piping system is drained, a second smaller diameter tube is attached to the tube wall in the reduced diameter portion which extends from the outer end thereof into the main larger diameter portion thereof so as to enter the liquid held therein and cause draining thereof from the suppressor.
