The post does not relate to a maintenance report feedback to public flat house. The term "downpour" refers to a heavy rainstorm, and "Singapore" is a location, but there is no mention of any maintenance or housing-related issue. Therefore, the post does not meet the criteria for a maintenance report feedback to public flat house.
