4. Fittings connect and change the directions of water line pipe runs. These fittings are identified by symbols.
a. Figure 1-9 shows water-pipe-fitting symbols.

5. Valves control the flow of water. Gate valves turn water flow on or off. Globe valves control flow of water. Faucets turn water on and off at a fixture such as lavatory or sink.
a. Figure 1-11 shows symbols used for valves.
