Leaking when flushed

It’s only leaking when it’s flushed

If the toilet only leaks when it's flushed, there are a couple of places that you can check to find the source of the leak. Sometimes, it might seem as if the soil pipe is leaking from the back (the bottom thick pipe running to outside), but this may not be the case as water sometimes runs from above onto the lower pipe.

There are 2 types of toilets in our homes. Which one do you have?
