b. Testing of Drainage System
After the electrical installation is completed, carry out the testing of the drainage system.
During the test, check if the water correctly flows through the pipelines. Carefully observe the joints
to ensure that there is no leakage. If the unit is to be installed in a new house, carry out testing before
decorating the ceiling.
