The possibilities of leaks are much less than inmany of the types now in use.

To renew the gasket G, the cockis closed tight. When in the closed position all parts exceptthe spindle and body may be removed and cleaned or renewedas occasion may demand. Any lime in the outlets for steamand water in the spindle may be loosened and readily blown outas soon as the reassembling is completed.
