Ball valve drain assembly with PEX-lined nipple, hose adapter and brass cap

Ball valves have a lever handle that opens and shuts the valve. They are more reliable than gate valves, and more likely to actually be able to open and close after years in an installation serving a hard-water area. The picture above right comprises a drain assembly consisting of a brass hose adapter at left, the ball valve in the middle and a galvanized steel, plastic-lined dielectric nipple on the right.
