Should I inform the property if the toilet is closed?

Do a closed water test, mainly to check the waterproof, which needs to be confirmed by the downstairs residents. It's no use looking at the property because there is a leak downstairs. The actual use is the residents downstairs. Therefore, to do the closed water test at ordinary times, we should contact the downstairs through the property. The purpose of closed water test is to prevent water leakage.

Independent toilets are particularly popular. The advantage is that each room can be used at the same time, especially during peak hours, which can reduce mutual interference. Each room has clear functions and is convenient and comfortable to use. Disadvantages are large space occupation and high construction cost.
