Regular cleaning with appropriate cleaning agents can help prevent the buildup of grime, mildew, and bacteria. Secondly, check for leaks around the base and tank and fix them immediately to prevent further damage. Thirdly, check the fill valve and flapper for wear and tear, and replace them if necessary to prevent water wastage and running toilets. Fourthly, avoid flushing non-flushable items down the toilet to prevent clogs. Keep a plunger on hand to unclog the toilet in case of a blockage. Lastly, consider having a licensed plumber perform a regular inspection of your toilet to ensure it is functioning properly and to identify any potential issues before they become bigger problems. By following these tips, you can help keep your toilet in good working condition and avoid costly repairs.
