Warning: Valves should be placed in a partially open position prior to working on a valve or removing
it from service to vent pressure or drain product that may be trapped in the body cavity. When remov-
ing threaded end valves from the line, apply wrenches in the same manner used for installation and
NOT to the valve body section or opposite tailpiece as this may result in breaking loose the threaded
tailpiece to body joint.
