It seems that the post does not mention anything related to maintenance report feedback for a public flat house in Singapore. The word "rained" does not provide any contextual clues that would suggest otherwise. Therefore, the answer is "False" for the question "Does the post relate to a maintenance report feedback to public flat house?"
