Is the quality of high-rise secondary water supply tested every year?

Tap water must be inspected all the time when it leaves the factory, but it will not be known at the terminal. It depends on whether your property is responsible for you. There is no mandatory annual inspection of terminal water, but you can suggest to the property that the water quality test report be posted on the bulletin board at some time every year.

At present, the secondary pollution in this society is very serious, so it is necessary to do this step.
