​​​Work with water pipes and connected equipment

No work may be performed on equipment or piping connected to the water.

You may (by an agreement with your immediate superior) replace exterior water tap if you easily see it (when you are in the area) and if any leakage do not create damage to the material around.

​​​​​​​Installation of dishwashers and washing machines should not be done, if a plumber has not trained you. Training must be documented. Dishwasher or washing machine must never be connected if the machine is not in a room with a drain, consult a plumber.
