How Do You Fix Flushing Problems With a Toilet?

Repair a toilet with flushing problems by cleaning out the holes under the rim. Use the end of a wire coathanger to ream out the holes, and then dissolve the scale using a toilet-bowl lime remover. The process takes about an hour.

  1. Remove the scale mechanically

    Straighten out a coathanger, and push one end into each hole under the rim of the toilet. This process breaks up the softer scale build-up so it dissolves and washes away.

  2. Use the limescale remover

    Turn off the water to the toilet, and flush so the tank empties. Lift the flapper valve, and tie it so it remains open. Pour 1 cup of the commercial lime remover into the opening the flapper normally covers. Allow the solution to work for at least an hour.

  3. Flush away the scale

    Mix 1/2 cup of the lime remover with 1/2 cup of water. Pour this mixture into the hole under the flapper, and close the valve. Turn on the water, and allow the tank to fill. Flush the toilet to rinse away the product.

  4. Test the flush

    Pour a bucket of water directly into the bowl, and observe the flush. If the toilet still flushes slowly, the problem is in the drain. Call a plumber for repair.
