When it comes to choosing between key seal and pan cone rubbers, we highly recommend going for the pan cone. In our experience, they tend to last longer and are less likely to cause any leaks. So let’s get started and fix that annoying problem once and for all.

Replacing the rubber seal at the back of the toilet is not a difficult task, but there is a little trick to it. This rubber seal, known as the pan cone rubber, is located where the pipe connects from the toilet cistern to the pan.
