Task D-12 Installs, tests and services potable water distribution systems
Task Descriptor
Plumbers install potable water distribution systems by connecting the piping from the water service to equipment and fixtures. Plumbers must select the appropriate materials and properly size the system to deliver adequate water supply. By installing cross-connection devices, the water supply is protected from contamination. In some jurisdictions plumbers may be required to attain additional training to install and certify cross-connection devices. For the purpose of this standard, service includes troubleshooting, diagnosing, maintenance and repairs.
