Toilet bowl maintenance rules (1) The toilet cannot be used and stored in a water environment below 0°C. Otherwise, water ice expansion may break the porcelain. (2) Do not pour the overheated water into the toilet so that it does not burst. (3) To prevent damage and water leakage, do not hit the ceramic. (4) Please don't throw news items such as newsprint, paper diapers, and sanitary napkins into the toilet. (5) Do not clean with steel brush and strong organic solution, so as not to damage the glaze of the product and corrode the pipe. (6) In order to keep the toilet surface clean and the flushing function normal, use a long-handled nylon hair brush and soapy water or neutral detergent to clean the pipes and flushing holes. It is recommended to clean it at least once a week. (7) Please clean the filter at least once a month to prevent the filter from being clogged, causing the water tank to enter the water slowly or without water and affect normal use. (8) Do not use chlorine-containing cleaners in the water tank. This may damage the devices inside the tank and cause leakage or damage to the structure of the building.
