Don't go out and buy a new toilet or pay an arm-and-a-leg to change the seal!
Installation instructions:
1.) Turn off water supply.
2.) Hold the flush ball open by depressing the flush pedal.
3.) Grasp the underside of the old seal and pull towards you to remove.
4.) Clean the rim and bowl area where the old gasket previously sat.
5.) Release flush pedal and allow the flush ball to close.
6.) Clean the flush ball.
7.) With the flush ball closed, put the new seal in and press outwards
to ensure that it is firmly in place.
8.) Reopen the flush ball and spread a lubricant in the areas where the gasket
will contact the flush ball.
9.) Open and close the flush ball several times, then press down on the gasket
to ensure it is properly positioned.
10.) Turn on the water supply, add water to the bowl and ensure that there are
no leaks.
